Samarium Cobalt SmCo Magnets

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°C. 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.

Therefore, Samarium cobalt magnet are applied in Aerospace, National defense and Military industry, Microwave Devices, Communication Equipment, Medical Device, Instrument, Sensor, Motor, Magnetic cranes, etc.

The characteristics

1. Good coercivity

2. Good temperature stability

3. Corrosion protection, rust prevention and high temperature resistance are better than NdFeB
