SmCo permanent magnets include Sm1Co5 and Sm2Co17. They have three principal characteristics: magnetic stability, temperature stability and good corrosion resistance. They can work up to 350 degrees C are suitable for making high performance permanent magnet motors and some special environment products.

Main features: 
1. An alloy composed of SmCo5/Sm2Co17
2. Extremely hard & brittle 
3. High demagnetization resistance 
4. Limited raw material supply result high in cost 
5. Outstanding thermal stability 
6. Excellent anti-corrosion properties
