1:5 SmCo Magnet
SmCo1:5 Magnet is also called SmCo5, the highest working enviorment can be 250℃.Based on Sm,Co and some other metals. After processing of melting, milling, compression moulding and sintering. To make work blank with different levels of performance.
2:17 SmCo Magnet
SmCo2:17 Magnet is also called Sm2Co17, the highest working can be 350℃.Based on Sm, Co, copper, iron zirconium and some other metals. After processing of melting, milling, compression moulding and sintering. To make work blank with different levels of performance.
One Sm atom and five Co atoms combine to form one SmCo5 atom.
Two Sm atoms and seventeeen Co atoms combine to form one Sm2Co17 atom.
Their maximum magnetic energy products are SmCo5(25 MGOe), Sm2Co17 (32 MGOe) respectively.
Their reversible temp coefficient are SmCo5(- 0.05% / ℃), Sm2Co17(- 0.03% / ℃)
