Application of Rare Earth Magnets HISTORY

(1) magnetic pin
(2) vacuum technology
(3) magnetic field of storage, such as bias.
�� �� rare earth permanent magnet as a permanent magnet material in the latest magnetic materials and the maximum principle can be applied to all these areas. Western NdFeB use of the world's largest area of computer disk drives in the voice coil motor (VCM), or a total of 57%. And China's largest area is the use of audio (27 per cent) and motor (25%), the Western world this two were 5 per cent and 17 per cent. Moreover, China's VCM magnets only: 1%.
�� �� This is because the production of NdFeB magnets in China for the majority of middle and low performance products for the electrical and audio in applications, a common market of the so-called speaker-magnet that is such applications. VCM use of magnets of high-performance requirements: (BH) max> 318.4kJ/m3 (40MG0e), the processing of high accuracy, product consistency, and quick replacement. Such products are mainly the United States and Japan, rare earth permanent magnet manufacturer controlled by the position of the living. Magnetic resonance imaging devices, applications and NdFeB is a big field, China has just started, the Western world is 11%. Only China, such as the Shenzhen and Zhangjiagang in research and Preparation units, but have not yet taken shape industry. Oilfield except December 22 per cent of China is the third largest application areas, the Western zero. This is our field of petroleum special component that is related to the high volume of December. In short in the rare earth permanent magnet, particularly the application of permanent magnet NdFeB China has its own characteristics.
