SmCo magnet
Features: 1) Very high magnetic properties with good stability 2) Superior resistance to high temperature3) Curie temperature of majority is over 800oC 4) Excellent corrosion resistance capability5) No coating is needed for surface protection.
SmCo is made of thulium samarium and transition metal cobalt, iron and copper. It is the second generation of thulium magnet. SmCo has not only high Energy Product（14---28MGOe）and reliable coercive force, but also good temperature trait. Compared to NdFeB magnet, with valu Sm and Co in it. SmCo is suitable to high temperature. Since this material contents more percentage of valuable Sm and Co, the application is therefore not wider than others.
