The Samarium Cobalt magnets are one type rare earth matrial permanent magnets. It is manufactured by using powder metallurgy techniques, and which offer the best performance value.
SmCo magnets are also named with SoCo magnetic steels, SmCo permanent magnet, SoCo permanent magnetic iron and rare earth cobalt permanent magnet.
1. It is a high performance, low temperature coefficient permanent magnet with its high working temperature-350 degree centigrade. When working above 180 degree centigrade,
2. it's maximum energy prodcut BH and steady temperature are superior than NdFeB magnetic material.
3. It needn't to be coated because it is difficult to be eroded and oxidized.
4. SmCo magnets widely used in transduces, instruments, etc.
