Neodymium permanent magnet material available in the early 1980s, is now widely used in motor (motor), speakers (speaker), toys (toys) and some electrical appliances (electron), and other products. Components for ND2Fe14B. Have very high magnetic properties, the largest energy product (BHmax) higher than the ferrite (Ferrite) 10 times more. Its own mechanical properties is also very good, cutting different shapes and bored. High-performance products of the highest temperature of up to 200 degrees Celsius. Because of its material content easily lead to corrosion, according to different requirements of different surface coating. (Such as plating Zn, Ni, Au, Epoxy, etc. )
