1. SmCo magnet is also named with SmCo magnetic steel, SmCo permanent magnet, SmCo permanent magnetic iron and rare earth cobalt permanent magnet.
It was found at 1970's, and it is belong to second generation rare earth permanent magnet.
2. It was applied to many different fields.
3. It is a high performance, low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade, its maximum energy prodcut BH and steady temperature are superior than NdFeB magnetic material. It needn't to be coated because it is difficult to be eroded and oxidized.
