Cast Magnets(CKSC™)/
Rolled Magnets(CKSR™)
Characteristics of Fe-Cr-Co Magnet
CKSC/CKSR
- ・High remanence with low cobalt content, while maintaining characteristics of Alnico magnet
- ・Small temperature coefficient of remanence (-0.03%/K)
- ・Stable supply of raw materials because no rare earth elements are used
CKSR
- ・High degree of freedom in forming
