Feature of Sintered SmCo:
The best temperature characteristics in the rare-earth magnet family
Manufactured by powder metallurgical process involving the sintering of powder under vacuum.
Both grades of SmCo5 and Sm2Co17, commonly referred to as 1:5 and 2:17 material are available.
Good corrosion resistance and no special surface treatment required excellent for compact designs
where high working temperature is a major concern. 
Grinding and slicing operations possible
Application:
applied to various electric motors, instruments, sensors, detectors, radar, and other high-tech equip-
ment.
