Product Description

High Temperature Permanent SmCo Magnet

Permanent Samarium Cobalt magnets (SmCo) are composed of samarium, cobalt and iron. These rare earth magnets are extremely strong for their small size, metallic in appearance and found in simple shapes such as Arc, rings, blocks and discs.

Attributes 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, traveling wave tubes, linear actuators, satellite systems, motors where temporary stability is vital.
