The Development and Huge Industrial Capacity of NdFeB Magnets in China

Update:28 Sep 2020

Neodymium magnet for sale can be divided into bonded neodymium iron boron and sintered neodymium iron boron. As the third generation of rare earth permanent magnet materials, neodymium iron boron magnets have high performance and are widely used in energy, transportation, machinery, and medical care. , IT, home appliances and other industries, especially with the development of knowledge economy represented by information technology, continue to bring new applications to the rare earth permanent magnet NdFeB industry and other functional materials, which will bring more broad areas to the NdFeB industry. Market prospects.

Neodymium iron boron magnets are tetragonal crystals formed by neodymium, iron and boron. The magnetic energy product of neodymium-iron-boron magnets is greater than that of samarium-cobalt magnets. It was the material with the largest magnetic energy product in the world at that time. It is the most magnetic permanent magnet today and the most commonly used rare earth magnet.

Its hard texture, stable performance, and good cost performance, so its application is extremely wide. But because of its strong chemical activity, it must be coated on the surface. Neodymium magnets exist in daily electronic products, such as hard drives, mobile phones, earphones, etc.

As one of the most important application fields of rare earth materials, NdFeB materials are one of the important basic materials supporting the modern electronic information industry and are closely related to people's lives. With the popularization of communication equipment such as computers, mobile phones, and car phones, and the rapid development of energy-saving vehicles, the world's demand for high-performance rare earth permanent magnet materials has grown rapidly. Neodymium magnet is indispensable as the "heart" of permanent magnet variable frequency air compressor. In the first decade of this century, China has completed the transition from a major producer of permanent magnet materials to a major producer of high-efficiency motors. A large number of rare earth permanent magnet motors produced in China are equipped with air compressors and have begun to be exported to European and American markets. The development and huge industrial capacity of China's rare earth Permanent Magnet Motor Assembly lead the trend of the world's frequency conversion air compressors.
