Samarium Cobalt


Samarium Cobalt Magnets

Known as rare earth magnets, Samarium Cobalt (SmCo) are alloys of the Lanthanide group of elements. SmCo magnets have been commercially available since the early 1970s, first as a 1:5 type alloy, and later with the introduction of the 2:17 type.

Both alloys offer outstanding thermal stability and excellent corrosion resistance. The 2:17 alloyoffers the advantage of superior thermal stability, and energy products up to 33 MGOe. They are price-sensitive and chip easily.

SmCo - Injection Molded

SmCo - Bonded

SmCo - Sintered

SmCo Magnetic Performance

With the exception of Alnico magnets, SmCo magnets offer the highest operating temperature of any magnetic material.


Common Applications for Samarium Cobalt

Due to their high operating temperature, magnetic performance across a broad temperature range, excellent corrosion resistance, and high output per unit mass.
