SmCo Magnets
|
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---350 degree centigrade.It needn't to be coated because it is difficult to be eroded and oxidized.SmCo magnet is widely used in motors watch transducers instruments positional detector generators radar and etc.
