Rare Earth SmCo magnet

Characteristics

SmCo magnet is a high performance low temperature coefficent permanent magnet, made of samarium and cobalt and other rare-earth elements.Its biggest advantage is its high working temperature---500 degree centigrade.It need not to be coated because it is difficult to be eroded and oxidized.

Applications

SmCo magnet is widely used in motors watch transducers instruments positional detector generators radar and etc.
