China's rare earth export volume and price rise in September

Customs statistics show that in September 2021, China's rare earth exports increased in volume and prices year-on-year; from January to September, China's rare earth exports increased in volume and prices. Due to the repeated pandemics of the major new crowns overseas and other reasons, the export volume in 2020 will decline, which contrasts with the significant year-on-year growth in the export volume in 2021. Export volume and price rose year-on-year in September Specifically, the export volume in September 2021 was 3920.2 tons, an increase of 95.7% year-on-year; the average export price was US$12.9/kg, a year-on-year increase of 37.1%. It is worth noting that the export volume in September 2020 was very small, mainly due to eventual reasons such as the new crown pandemic, which affected production and transportation. The monthly export volume from May to November 2020 was relatively low, reflecting the fact that 2021 The monthly export volume from May to November was relatively high year-on-year, making the export volume in 2021 exhibited a substantial increase. From January to September, the volume and price of exports rose year-on-year Data analysis shows that from January to September 2021, China's rare earth exports were 35,637.3 tons, and the export value was US$467.6 million, an increase of 35.1% and 84.4% year-on-year respectively. From January to September 2021, the average export price of rare earths was USD 13.1/kg, a sharp increase of 36.5% year-on-year. In addition, the export volume in September 2021 remained stable month-on-month, but the average export price declined slightly from the month-on-month period, down by US$0.5/kg from August.
Application of advanced soft magnetic materials in the motor industry

Application of advanced soft magnetic materials in the motor industry

In the last few decades, the demand for new magnetic materials in the automobile and other industries has surged. In the mid-1990s, the first parts made of soft magnetic composite materials were born. The use of these soft magnetic composite materials (SMC) The trend has continued to grow. The first soft magnetic material parts are ignition cores for automobiles, which are widely used in most general vehicles. They are compacted into a round shape, and no insulating tape is used to protect the primary winding from the coil. Today, powder metal and soft magnetic composite material technology has come a long way, and it provides technological changes that did not exist before. The correct soft magnetic material makes the motor flux transmission faster, consumes less energy, and the motor structure becomes more compact. The motor can use higher frequency, denser electromagnetic, high penetration, and greatly reduce the eddy current loss of the rotor/stator. Electric motors use direct current (DC) stored in batteries or alternating current (AC) from generators and power grids to convert electrical energy into mechanical energy. They can be used in electric vehicles, small household appliances, industrial fans and pumps, machine tools, and large ships and aircraft for propulsion. Continued research on soft magnetic composite materials (SMC) has shown that they have great potential in DC and AC applications, by allowing engineers to develop new innovative designs that improve the magnetic induction of core materials at low and medium frequencies. Soft magnetic materials are composed of electrically insulating ferromagnetic powders. When optimizing particle size, shape and microstructure, they have many valuable advantages, including magnetic and thermal isotropy, high permeability, low coercivity, and Curie High temperature and low total iron loss. "Soft" means that in the sense of magnetism, the term has nothing to do with the hardness of the material. Soft magnetic materials are easy to magnetize and demagnetize. Permanent, or "hard" magnets always maintain their magnetization. The soft magnetic composite material is made of iron powder particles with high purity and compressibility and thin and uniform laminates bonded together. The coating provides high resistivity, insulates the edges of each individual particle, and limits the generation of eddy currents. Soft magnetic composites are ferromagnetic powder particles ideally coated with a uniform electrically insulating film, just like any other powdered metal part. Soft magnetic composite materials are compacted using heated molds to promote higher density, permeability, and inductivity. The soft magnetic composite material depends on the final application, and the magnetic properties are affected by various corresponding parameters, including the alloy material used, the density of the final part (saturation sensitivity and permeability are affected by the density), the sintering temperature, the ...

Relevant analysis and countermeasures on the skyrocketing price of rare earths

The Chinese Society of Rare Earths recently visited rare earth application companies, mainly key NdFeB factories, to investigate the production and operation of each unit. Companies generally report that with the state’s policy support for corporate innovation, due to the importance of high-tech development opportunities and the benefits brought by the dual-carbon strategy, the rare earth permanent magnet industry has generally ushered in a new round of prosperity in recent years. Market demand has grown steadily, and both production and sales have been booming. At the same time, companies also expressed great concern about the current unfavorable factors, especially the soaring price of raw materials such as praseodymium and neodymium. Since the beginning of this year, the price of metals such as praseodymium and neodymium has been like a wild horse. From 327,000 yuan/t in October last year, it has soared to 740,000 yuan/t recently. For cobalt, which is also in short supply, the highest price from 2019 to now is only 390,000/t. (The abundance of cobalt is 25 and the abundance of neodymium is 41.5). Under this unbearable pattern of raw material supply, the following dilemmas have appeared: First, the production cost has risen sharply, and the efficiency of permanent magnet companies has decreased significantly or suffered serious losses, which has reduced local taxes and employment, and some companies are unsustainable; second, raw material procurement Difficulties, due to insufficient supply to further increase prices; third, companies cannot sign long-term orders; long-term orders that have already been signed have brought multiple leading companies due to the price difference (that is, the difference between the low price of raw materials at the time of signing and the high price of raw materials purchased) Hundreds of millions of real and potential losses have come; fourth, the consequent increase in the price of rare earth permanent magnet companies, is gradually transmitted to terminal application companies such as motors, increasing the operating difficulties of these companies; fifth, there are widespread accounts in the rare earth permanent magnet industry. The longer period, coupled with the high price of raw materials, has sharply increased the capital risk. These factors are very likely to lead to the reversal of the good situation of rare earth applications represented by rare earth permanent magnets. The above is a relatively intuitive negative effect on the business activities of the company. It will also have the following impacts on the rare earth permanent magnet industry and related downstream enterprises and the entire industry chain, as well as the high-tech industries involving rare earths. 1. Rare-earth raw material manufacturers have made huge profits, but this situation is unsustainable and does not conform to economic laws. The historical experience of various industries has proved this. The high price forces downstream ...

Carbon neutrality reshapes demand for rare earths

Rare earths: industrial vitamins, new materials and other downstream fields are widely used. Rare earths are the general name of 17 chemical elements, known as "vitamins of modern industry", and can be divided into light rare earths and heavy rare earths. The rare earth industry chain is mainly composed of upstream mining, midstream material preparation and downstream applications. Rare earths are widely used in metallurgy, military, petrochemical, glass ceramics, agriculture, new materials and other fields. Rare earth permanent magnet materials account for 42% of my country's rare earth consumption and are the most important track downstream of the rare earth industry chain. Rare earth permanent magnets are currently the most comprehensive permanent magnets. NdFeB has the advantages of strong magnetism, resistance to magnetic loss, and temperature stability. It is the most widely used rare earth magnet. High-performance NdFeB permanent magnets are used in energy-saving products such as wind power and new energy vehicles. Other NdFeB permanent magnets are mainly used in magnetic separators and electroacoustic applications. China has the most abundant rare earth resources, and it is difficult to provide more supply increments at home and abroad in the short term. China is the country with the richest rare earth resources in the world. The rare earth reserves are 44 million tons REO, accounting for 37% of the global reserves. The Bayan Obo mine reserves are as high as 35 million tons. The world's largest rare earth mine. In 2020, the global output of rare earth concentrates will reach 240,000 tons, and China's output will be 140,000 tons, accounting for 58%. It is the main supplier of rare earth concentrates. In the short term, it is difficult to provide more rare earth supply increments both at home and abroad. The domestic policy side "indicator control + industry integration" regulates rare earth production, and the increase mainly comes from the upward adjustment of indicators. The domestic rare earth output is controlled by the total index. In 2020, the mining index will be 140,000 tons and the smelting separation index will be 135,000 tons. The adjustment of aggregate indicators is related to the supply and demand side of the market, and demand growth may drive a certain increase in aggregate indicators. The increase in foreign production capacity is facing a bottleneck, and the project under construction is too early to start production. The main production capacity of foreign rare earth mines are concentrated in Mount Pass, Australia, and rare earth mines in Myanmar; Mountain Pass has a production capacity of 40,000 tons per year, which basically reaches the upper limit; Linus has a production capacity of 25,000 tons per year, and has a production capacity of 25,000 tons per year. Utilization rate is about 75%; Myanmar rare earth mines are an important source of domestic heavy rare earths. In 2020, the import volume will be about 20,000 ton...

Current Status and Prospect Analysis of NdFeB Permanent Magnetic Materials

Rare earth permanent magnet materials refer to alloys formed by rare earth metals and transition metals. The permanent magnetic material made by a certain process has extremely strong magnetism and can be maintained for a long time. This material is now divided into the first generation (RECo5), the second generation (RE2TMl7) and the third generation of rare earth permanent magnet materials (NdFeB). The emergence of neodymium iron boron (NdFeB) rare earth materials and the rapid development of its application in the electronic field have set off a wave of neodymium iron boron electroplating in the electronic electroplating industry. This is because NdFeB material is one of the important basic materials in electronic information products and is closely related to many electronic information products. With the popularization of communication equipment such as computers, mobile phones, and car phones, and the rapid development of energy-saving automobiles, the world's demand for high-performance rare earth permanent magnet materials has grown rapidly. NdFeB permanent magnets are known as the "magnet king" and are one of the magnetic materials with better comprehensive performance in the current industrial production. It is the rare earth permanent magnet material with the highest output and the most widely used. NdFeB permanent magnet process technology and application fields have been developed rapidly in recent years, and have gradually developed into one of the mainstream magnetic materials in the market, and play an important role in promoting the upgrading of downstream products, energy saving and emission reduction, and sustainable development. . NdFeB permanent magnets have good mechanical properties and high energy density, which is conducive to the lighter, thinner, miniaturized or ultra-miniaturized magnetic components. The emergence of neodymium iron boron permanent magnets not only makes electro-acoustic motors, instrumentation, magnetic separation magnetization, medical equipment and other equipment develop in the direction of miniaturization, high frequency, high performance, low loss, and low noise, but also with the characteristics of energy saving and environmental protection. Its applications have expanded from traditional fields to emerging fields such as new energy vehicles, wind power generation, energy-saving appliances, and aerospace. For a long time, most of my country's sintered NdFeB manufacturers produce low-end products and face greater market competition pressure. In recent years, driven by the development of strategic emerging industries such as energy conservation and environmental protection, new energy vehicles, information technology and high-end equipment, some domestic companies have continuously introduced advanced production technology, equipment and management experience of foreign NdFeB permanent magnets, and invested funds to develop their own Research and development has promoted the rapid improvement of my...

China's rare earth exports increased significantly in July and prices rose slightly

The analysis of customs statistics shows that in July 2021, China's rare earth export volume was 3955.4 tons, a year-on-year increase of 144%; the average export price was US$16.5/kg, a year-on-year increase of 5%. July 2020 year 2021 year Year-on-year Export volume (tons) 1,620.30 3,955.40 144.1% Average price (USD/kg) 15.7  16.5  5.0% The outbreak of the overseas epidemic led to transportation obstructions and other reasons, which led to a small export volume in July 2020, and the demand broke out in 2021, so it contrasted with the larger increase in July 2021. In addition, the cumulative export volume from January to July was 27,781 tons, an increase of 22.2% year-on-year; the export value increased by 72.6% year-on-year to US$364.1 million.

The domestic rare earth market rose sharply in July

Since the beginning of July, the prices of major rare earth products have risen rapidly, with praseodymium and neodymium oxide, terbium oxide, and dysprosium oxide rising by about 24%, 23%, and 11% respectively. The low season for rare earths this year is not weak, and it is strongly driven by downstream demand such as new energy vehicles. The pre-requisite effect of replenishment is obvious. Due to the advent of the rainy season and the aggravation of the epidemic, the supply of rare earths in Myanmar has been disturbed. Superimposed on the recent national environmental protection inspections, some smelting and separation plants have cut production and stopped production. Supply and demand basically form strong support in the face of rare earth prices. Rare earth permanent magnet materials (NdFeB) account for about 80% of the output value of the downstream of the rare earth industry chain, and are mainly used in traditional automobiles, new energy automobiles, wind power, energy-saving inverter air conditioners and other fields. The amount of NdFeB for new energy vehicles is about 3-5 kg, which is 3-5 times that of traditional cars. Assuming that the output of new energy vehicles will reach 18 million in 2025, the corresponding NdFeB demand will reach 54,000 to 90,000 tons in 2021. In 2025, the demand for neodymium-iron-boron in the new energy vehicle industry will grow at an average annual rate of about 40%. In 2025, new energy vehicles may become the largest downstream application of rare earths. The demand for new energy vehicles has begun to explode. The downstream demand for carbon-neutral wind power and energy-saving inverter air conditioners continues to pick up. The downstream demand for rare earths is expected to continue to improve; during the "14th Five-Year Plan" period, the domestic rare earth supply will still be restricted by the total mining index. Supply-side high-pressure policies such as crackdowns and environmental protection will continue. It is expected that the increase in overseas supply in the next five years will be relatively limited, and the global supply and demand of rare earths may be in a tight balance for a long time. Raise the forecast for the price of praseodymium and neodymium oxide in 2021 to 800,000 yuan/ton, and maintain the forecast for the high prices of dysprosium oxide and terbium oxide at 3 million yuan/ton and 15 million yuan/ton. The price of rare earths is expected to open up for a long time. In recent years, the supply-side structural reform of the domestic rare earth industry has continued to advance, and applications such as downstream magnetic materials have developed rapidly, and the fundamentals of supply and demand are expected to enter a virtuous cycle.

What is rare earth permanent magnet material? Why is it so important?

Talking about rare earths is inseparable from rare earth permanent magnet materials. What is rare earth permanent magnet material? Today we will come to popular science. First, let's understand what is a permanent magnet material? Refers to materials that can maintain constant magnetic properties once they are magnetized, and are widely used in high technology. Those who have studied high school physics know that magnetic energy generates electricity, commonly known as "electromagnetic induction" phenomenon, and the principle of modern generators is derived from this. Permanent magnet materials can provide constant magnetism and provide a constant energy basis for motor operation. Why are rare earth permanent magnets so precious? Rare earth permanent magnet, that is, the permanent magnet material contains rare earth metal elements. At present, the well-known rare earth permanent magnet materials are mainly rare earth cobalt permanent magnet materials and neodymium iron boron permanent magnet materials. Rare-earth permanent magnet materials are currently known as a permanent magnet material with the highest comprehensive performance. The magnetic energy product of cobalt permanent magnets can reach 150 times that of carbon steel, 3 to 5 times that of Alnico permanent magnets, and 8 to 10 times that of permanent magnet ferrites. Neodymium iron boron magnets have extremely high magnetic energy and are called the contemporary "king of permanent magnets". They are widely used in electronics, machinery and other industries with their excellent performance. Due to the use of rare earth permanent magnetic materials, not only has promoted the miniaturization of permanent magnetic devices and improved the performance of products, but also promoted the production of some special devices, which has the effect of becoming gold.

China's rare earth exports fell 3.8% in June

China has a vast territory and contains precious and scarce rare earth resources. Rare earths play a core role in industrial metallurgy, chip manufacturing, and even aerospace. Statistics show that China's rare earth reserves account for 36% of the world's total reserves, and it is a veritable rare earth country. In addition, China also bears 90% of the world's rare earth exports. According to the latest data from Chinese officials on Tuesday (July 13), in June 2021, China exported a total of 4012.4 tons of rare earths, a decrease of 3.8% compared with the export volume of 4171 tons of rare earths in May. Since China currently holds a large global supply of rare earths in its hands, China is the source of rare earth resources in many countries. According to statistics from relevant U.S. agencies, in 2018, the U.S. rare earth supply was 100% dependent on foreign imports, and 80% of the rare earths came from China. Among the 35 rare earth elements recognized and used in the United States, 13 are imported from China. It can be seen that the United States cannot do without China's rare earth resource market. Rare earth permanent magnet materials have a wide range of applications, including traditional industries such as computers, automobiles, instrumentation, household appliances, and emerging industries such as wind power generation, new energy vehicles, and energy-saving elevators. China's rare earth permanent magnet material industry is showing a trend of stable development, with a compound annual growth rate of 11.4%. Thanks to the strong support of the Chinese government and the continued growth of market demand in downstream industrial motors, wind turbines, new energy vehicles, consumer electronics and other applications, the industry is expected to continue to grow in the future, and the consumption of rare earth permanent magnet materials is expected to further expand , The consumption is expected to reach 164,000 tons in 2023. As China has begun planning for the export of rare earth resources in recent years, official sources indicated that it will issue the "Rare Earth Regulations" as soon as possible to regulate the development of the industry.

Analysis of the factors and influences of the price fluctuation of magnetic materials

Since the second quarter of 2020, with the domestic economic recovery, domestic and foreign epidemics, economic and international relations, and factors such as China’s environmental protection and overcapacity at the front end of some related industrial chains, almost all relevant factors have been added to the magnetic material raw materials. The price of magnetic material raw materials is on the road. Many varieties have more than doubled, and individual varieties have increased by more than 3 times, and the supply of some varieties is tight. Here is a brief analysis of the reasons and effects of the sharp increase in the prices of magnetic materials and raw materials in the past year for the reference of industry enterprises. The main factors leading to the rise of raw materials in recent years 1. Environmental protection policy restrictions and strict management and control have led to abnormal production and suspension of raw material enterprises 2. Insufficient power supply in winter, and power cuts in many places, resulting in abnormal production of raw material enterprises 3. Production restrictions and process adjustments of domestic steel companies have led to a tightening of domestic iron red 4. The spread of the new crown epidemic abroad has caused some raw material companies to stop production, and exports to China have decreased and prices have risen sharply (such as upstream iron ore and related raw materials) 5. Foreign environmental protection management has caused the production line to stop production (for example, South Korea has stopped several desiliconization lines due to environmental protection reasons) 6. The growth of new energy vehicles stimulates the price of related raw materials (such as cobalt) to continue to rise 7. The domestic epidemic is effectively controlled, and the economic recovery is superimposed on the country's new infrastructure to stimulate the increase in domestic economic development demand 8. China's new energy application market continues to grow (solar energy, wind power, electric vehicles, etc.) 9. The domestic and international market demand for testing, epidemic prevention, control, and epidemic control products and the growth of demand for housing economy 10. The foreign epidemic has led to an increase in imports of Chinese products and dependence on a certain period of time 11. Some high-end raw materials have been restricted by the export of developed countries such as the United States 12. Unlimited loose stimulus of the US currency, using the dominant position of the US dollar to release water, increasing the risk of inflation, pushing up commodity prices 13. The global supply of new crown vaccines has increased, the epidemic situation in some countries has been gradually brought under control, and the resumption of production has increased the demand for bulk commodities 14. The impact of international political turmoil (such as the continuous turmoil of the military coup in Myanmar aff...

The universal application of rare earth metals promotes the accelerated development of the global market

The latest report from Fairfield Market Research pointed out that the global rare earth (REE) market is witnessing a boom, and its end users are at the forefront of revolutionary changes. Generally understood as neodymium, cerium, praseodymium, lanthanum, yttrium, and dysprosium, rare earth elements or metals are essential for the automotive and consumer electronics industries. These elements are used in the production of hybrid and electric vehicles, computers, superconductors and batteries. As the world gets closer and closer to digital reality, their applications are becoming wider and wider. With the increase in sales of electric vehicles, the output of rare earth elements is also increasing Global demand for rare earth elements is expected to be driven by the shift to electric vehicles. Fairfield Market Research pointed out that by 2040, approximately 50% of traditional cars will be replaced by electric or hybrid cars. The urgent need to reduce automobile pollution and suppress carbon dioxide pollution is expected to benefit the sales of electric vehicles, which use neodymium and praseodymium in battery production. Government subsidies for the production and purchase of electric vehicles and better charging infrastructure are expected to prompt users to make conscious travel choices, thereby supporting the growth of the rare earth market throughout the forecast period. Increasing use of ceramic tiles to promote the application of rare earth elements in polishing After a slowdown in 2020, the recovery of construction activity is expected to promote the application of rare earth elements such as lanthanum, yttrium, cerium, neodymium and praseodymium. These are used in the ceramic industry to produce tiles. Cerium oxide increases the glaze effect of the tiles. The government's regulations to encourage new home buyers and ongoing renovation and renovation activities are also expected to boost this sector and increase the demand for rare earth elements. Fiber optic networks and consumer electronics expand the global rare earth element market The report also predicts that the exponential growth in sales of consumer electronics products (such as smartphones, tablets, laptops and other devices that require higher bandwidth and high processing speed) may drive the demand for better fiber optic cables. Initiatives to promote the digitalization of rural areas in developing economies, as well as projects to create large-scale fiber optic cable networks, are expected to boost the global rare earth element market. Holmium, neodymium, and erbium are widely used to produce high-efficiency active fibers. As we all know, these metals have heat resistance, high conductivity and magnetism, which makes them ideal for electronic products. China will pave the way for its booming electronics industry Geographically, the Asia-Pacific region will lead the global rare earth market, and China will pave the way for the global rare earth market.

The current situation of rare earth market and its mid- to long-term forecast

After experiencing the prosperous scene of rising volume and prices in the first quarter, the price of rare earth products in the second quarter continued to decline, and the domestic rare earth market was no longer good. However, since June, the rare earth permanent magnets sector has oscillated. On June 3, stimulated by the news, there was a short-term daily limit wave, but then it immediately entered an adjustment period. Regarding the later trend of the rare earth market, the analysis believes that the domestic rare earth product demand is not good in the short term, and the market outlook will maintain an overall weak operation. However, in the medium and long term, the structural inflection point of the supply and demand of the rare earth market has come, and it will enter a medium and long-term steady upward cycle. In the future, rare earth prices will increase steadily and may even start a new round of market doubling. Short-term: poor demand or difficult to change the weak market Since the second quarter of this year, the price index trend of the domestic rare earth market has continued to fall, the price of domestic praseodymium and neodymium rare earths has continued to fall, the price of heavy rare earths has fallen, and the weak rare earth market is difficult to change. In terms of prices, domestic mainstream products such as neodymium oxide, metal neodymium, neodymium praseodymium oxide, neodymium praseodymium alloy, and praseodymium metal have continued to decline, and the downward trend is obvious. As of June 7, the domestic rare earth prices of neodymium oxide, metallic neodymium, neodymium praseodymium oxide, and neodymium praseodymium alloys have all fallen by about 20% from the beginning of April. The continued decline in domestic rare earth product prices is closely related to poor demand. First, downstream permanent magnet manufacturers are actively stocking up in the early stage, increasing on-site inventory, and generally not being enthusiasm for restocking, resulting in limited transactions in the domestic rare earth market. The upper, middle and lower reaches are mainly wait-and-see. Traders have serious resistance to high prices and tend to purchase at low prices. Second, the sales of downstream new energy vehicles have slowed down, and the rare earth industry has cooled down due to this impact. Data show that in May, the sales volume of my country's auto industry is estimated to be 2.204 million vehicles, down 2.1% from the previous month. At the same time, affected by factors such as chip shortages, soaring commodity prices, and the appreciation of the renminbi, the performance of the new energy automobile industry and air-conditioners this year may have fallen short of expectations. Affected by the decline in the market, since April, relevant rare earth companies have continued to lower the listed prices of rare earth products, and the market's negative sentiment has gradually increased. On June 7, Southern Rare Eart...

What are the ways to avoid corrosion on the surface of neodymium magnets?

Compared with permanent magnet materials such as ferrite, neodymium magnets (NdFeB magnets) have excellent magnetic force and are also the most commonly used rare earth magnets. They are widely used in electronics, machinery, medical equipment, toys, smart homes, hardware machinery, aerospace And other areas. However, neodymium magnets (NdFeB magnets) are very susceptible to corrosion, so how to avoid the corrosion of neodymium magnets? In this article, we will introduce several conventional methods to avoid corrosion of neodymium magnets. 1). Phosphating Phosphating is a process of forming a phosphate chemical conversion film by chemical and electrochemical reactions. Phosphating has the following purposes: 1. Protect the base material from corrosion to a certain extent. 2. Used as a primer before painting to improve the adhesion and corrosion resistance of the film. 3. It plays a role of reducing friction and lubricating in the process of metal cold working. 2). Electroplating Electroplating is the process of plating a thin layer of other metals or alloys on the surface of other metals through electrolysis. The electroplating process is the process of using electrolysis to attach the surface of the metal or other materials to a layer of metal film, thereby preventing metal oxidation (such as corrosion). Improve wear resistance, conductivity, reflectivity, corrosion resistance and enhance aesthetics. Except for neodymium magnets, the outer layers of many coins are electroplated. 3), Electrophoresis Under the action of an electric field, the charged particles move towards the opposite electrode, which is called electrophoresis. The technique of separating charged particles by different speeds of charged particles in an electric field is called electrophoresis technology. Electrophoresis is one of the anti-corrosion surface treatment technologies widely used in sintered NdFeB and bonded NdFeB permanent magnets. The electrophoretic coating not only has good adhesion to the surface of the porous magnet, but also has the characteristics of resistance to salt spray, acid and alkali corrosion.
  • China's rare earth export volume and price rise in September

    Customs statistics show that in September 2021, China's rare earth exports increased in volume and prices year-on-year; from January to September, China's rare earth exports increased in volume and prices. Due to the repeated pandemics of the major new crowns overseas and other reasons, the export volume in 2020 will decline, which contrasts with the significant year-on-year growth in the export volume in 2021. Export volume and price rose year-on-year in September Specifically, the export volume in September 2021 was 3920.2 tons, an increase of 95.7% year-on-year; the average export price was US$12.9/kg, a year-on-year increase of 37.1%. It is worth noting that the export volume in September 2020 was very small, mainly due to eventual reasons such as the new crown pandemic, which affected production and transportation. The monthly export volume from May to November 2020 was relatively low, reflecting the fact that 2021 The monthly export volume from May to November was relatively high year-on-year, making the export volume in 2021 exhibited a substantial increase. From January to September, the volume and price of exports rose year-on-year Data analysis shows that from January to September 2021, China's rare earth exports were 35,637.3 tons, and the export value was US$467.6 million, an increase of 35.1% and 84.4% year-on-year respectively. From January to September 2021, the average export price of rare earths was USD 13.1/kg, a sharp increase of 36.5% year-on-year. In addition, the export volume in September 2021 remained stable month-on-month, but the average export price declined slightly from the month-on-month period, down by US$0.5/kg from August.

  • Application of advanced soft magnetic materials in the motor industry

    In the last few decades, the demand for new magnetic materials in the automobile and other industries has surged. In the mid-1990s, the first parts made of soft magnetic composite materials were born. The use of these soft magnetic composite materials (SMC) The trend has continued to grow. The first soft magnetic material parts are ignition cores for automobiles, which are widely used in most general vehicles. They are compacted into a round shape, and no insulating tape is used to protect the primary winding from the coil. Today, powder metal and soft magnetic composite material technology has come a long way, and it provides technological changes that did not exist before. The correct soft magnetic material makes the motor flux transmission faster, consumes less energy, and the motor structure becomes more compact. The motor can use higher frequency, denser electromagnetic, high penetration, and greatly reduce the eddy current loss of the rotor/stator. Electric motors use direct current (DC) stored in batteries or alternating current (AC) from generators and power grids to convert electrical energy into mechanical energy. They can be used in electric vehicles, small household appliances, industrial fans and pumps, machine tools, and large ships and aircraft for propulsion. Continued research on soft magnetic composite materials (SMC) has shown that they have great potential in DC and AC applications, by allowing engineers to develop new innovative designs that improve the magnetic induction of core materials at low and medium frequencies. Soft magnetic materials are composed of electrically insulating ferromagnetic powders. When optimizing particle size, shape and microstructure, they have many valuable advantages, including magnetic and thermal isotropy, high permeability, low coercivity, and Curie High temperature and low total iron loss. "Soft" means that in the sense of magnetism, the term has nothing to do with the hardness of the material. Soft magnetic materials are easy to magnetize and demagnetize. Permanent, or "hard" magnets always maintain their magnetization. The soft magnetic composite material is made of iron powder particles with high purity and compressibility and thin and uniform laminates bonded together. The coating provides high resistivity, insulates the edges of each individual particle, and limits the generation of eddy currents. Soft magnetic composites are ferromagnetic powder particles ideally coated with a uniform electrically insulating film, just like any other powdered metal part. Soft magnetic composite materials are compacted using heated molds to promote higher density, permeability, and inductivity. The soft magnetic composite material depends on the final application, and the magnetic properties are affected by various corresponding parameters, including the alloy material used, the density of the final part (saturation sensitivity and permeability are affected by the density), the sintering temperature, the ...

  • Relevant analysis and countermeasures on the skyrocketing price of rare earths

    The Chinese Society of Rare Earths recently visited rare earth application companies, mainly key NdFeB factories, to investigate the production and operation of each unit. Companies generally report that with the state’s policy support for corporate innovation, due to the importance of high-tech development opportunities and the benefits brought by the dual-carbon strategy, the rare earth permanent magnet industry has generally ushered in a new round of prosperity in recent years. Market demand has grown steadily, and both production and sales have been booming. At the same time, companies also expressed great concern about the current unfavorable factors, especially the soaring price of raw materials such as praseodymium and neodymium. Since the beginning of this year, the price of metals such as praseodymium and neodymium has been like a wild horse. From 327,000 yuan/t in October last year, it has soared to 740,000 yuan/t recently. For cobalt, which is also in short supply, the highest price from 2019 to now is only 390,000/t. (The abundance of cobalt is 25 and the abundance of neodymium is 41.5). Under this unbearable pattern of raw material supply, the following dilemmas have appeared: First, the production cost has risen sharply, and the efficiency of permanent magnet companies has decreased significantly or suffered serious losses, which has reduced local taxes and employment, and some companies are unsustainable; second, raw material procurement Difficulties, due to insufficient supply to further increase prices; third, companies cannot sign long-term orders; long-term orders that have already been signed have brought multiple leading companies due to the price difference (that is, the difference between the low price of raw materials at the time of signing and the high price of raw materials purchased) Hundreds of millions of real and potential losses have come; fourth, the consequent increase in the price of rare earth permanent magnet companies, is gradually transmitted to terminal application companies such as motors, increasing the operating difficulties of these companies; fifth, there are widespread accounts in the rare earth permanent magnet industry. The longer period, coupled with the high price of raw materials, has sharply increased the capital risk. These factors are very likely to lead to the reversal of the good situation of rare earth applications represented by rare earth permanent magnets. The above is a relatively intuitive negative effect on the business activities of the company. It will also have the following impacts on the rare earth permanent magnet industry and related downstream enterprises and the entire industry chain, as well as the high-tech industries involving rare earths. 1. Rare-earth raw material manufacturers have made huge profits, but this situation is unsustainable and does not conform to economic laws. The historical experience of various industries has proved this. The high price forces downstream ...
