Samarium Cobalt (SmCo) magnets 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 rings, blocks and discs.SmCo magnets are available in a number of different grades that span a wide range of properties and application requirements.
Temperature Effects of samarium cobalt magnets:
Samarium cobalt magnets can operate at temperatures up to 350
C , depending upon the grade and permeance coefficient. Sm
