Permanent magnet has highter magnetic properities,outstanding thermal stability and higher working temperature.

Permanent magnet is mainly made of rare-earth Samarium,Cobalt and other metal elements.It possesses such advantages as following:highter magnetic properities,outstanding thermal stability and higher working temperature(Max working temperature reaches 350°C).Besides ,SmCo magnet doesnt need to be coated due to its excellent corrosion resistance.SmCo magnet is widely used in computer disc drive,sensor,traveling wave tube,linear actuator,satellite systerm,radar,magnetic coupling,pump&valve and so on.
