SmCo magnet
Samarium cobalt magnets are composed of samarium, cobalt and other rare earth materials by proportioning, and made by smelting, pressing and sintering, and which have high BH, corrosion resistance and oxidation resistance and extremely low reversible temperature coefficients. SmCo5 and Sm2Co17, (BH)max is in range of 16 to 32 MGOe. Maximum working temperature reaches 350 degree . SmCo has an extreme low temperature coefficient and perfect corrosion resistance.
Compared with NdFeB magnets, SmCo magnets have stronger corrosion resistance, higher temperature stability and suitable for high temperature environments.
SmCo magnet are applied in Aerospace, National defense and Military industry, Microwave Devices, Communication Equipment, Medical Device, Instrument, Sensor, Motor, Magnetic cranes, etc.
