Description and Specification
Rare earth magnets are produced by powder metallurgical process. Nd2Fe14B is the main element in Neodymium and gives Neodymium strong magnetic power. 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 Zinc, Nickel, NiCuNi or Epoxy.
