Description
Neodymium block magnets are produced by powder metallurgical process. Nd2Fe14B 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.
Application
They are widely used in generator, circuit breaker, sensors, electro magnet.
