Current Status and Prospect Analysis of NdFeB Permanent Magnetic Materials
Aug 18,2021.

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 country's NdFeB manufacturing technology.
