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% / ℃)
SmCo magnets has the highest temperature of 350℃, it has high
magnetic properties,excellent temperature characteristic and
corrosion resistance.It is widely used in aerospace, electronic
instruments, magnetic pumps, high temperature lamps, sensors
andother fields. And it can be produced in different shapes(round,
square, ring, tile, bread), different properties (SmCo5 and
Sm2Co17),
Different sizes: (Wafer diameter1≤R≤100mm,Square≤130mm)
