Description
Sintered NdFeB magnets are produced by powder metallurgical process. NdFe14B is the main element in Neodymium and gives Neodymium strong magnetic power. In fact its maximum RH is more than ten times that of Ferrite. Neodymium has good machinability properties and can work well at temperatures up to 200 degrees Celsius. Since sintered Neodymium easily rusts, usually coated with such metals as Zn, Ni, NiCuNi, Au, Sn, gold or epoxy.
Application
They are widely used in motors, speaker, sensors, toys, electronic products
