High Temperature SmCo Block Magnet
Permanent Samarium Cobalt magnets(SmCo) are composed of samarium,cobalt and iron. These rare earth magnet are extremely strong for their small size, metallic in appearance and found in simple shapes such as Arc, rings, blocks and discs.
Attribute of Samarium Cobalt:
1. High resistance to demagnetization
2.High energy(magnetic strength is strong for its size)
3.Good temperature stability
Applications of Samarium Cobalt:
Computer disc drives ,sensors, high performance motors, Magnetic couplings, Magnetic separators, Areospace, Microwave parts, Automoble parts
