     Smco Magnet

 

Smco is made from Sm, Co and other Rare earth metal materials,mainly including SmCo5 and Sm2Co17.Magnetic property is second only to NdFeB. It is characterized by magnetic stability, heatresistance and strong corrosion resistance .The maximum operatingtemperature can come to 350 ℃; while it is breakable so that the processing is limited.
