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

    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

    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 ...
