SmCo magnets has higher magnetic properties, outstanding thermal stability and excellent corrosion resistance ability,made of samarium and cobalt and other rare-earth elements. Its biggest advantage is its high working temperature---350 degree centigrade. It needn't to be coated because it is difficult to be eroded and oxidized.Among all the magnet products,this material is the most expensive.

Our products are widely applied to the fields of Micro motor, watch movement rotor,pump couplings,Sensor and Optical Isolator,particularly where the magnet is required to work at high temperature in a corrosive environment.

Advantage
1)Excellent thermal stability
2)High magnetic properties
3)Good corrosion resistance
4)High resistance to demagnetization

Disadvantage
1)Difficult to machine
2)Expensive material (cobalt is market price sensitive)
