Samarium Cobalt (SmCo) magnets offer
designers a tremendous combination of extremely
high magnetic properties, outstanding thermal
stability and excellent corrosion resistance. As
part of the rare earth group of permanent
magnets, Samarium Cobalt (SmCo) magnets
typically fall into two families of materials.
They include rare earth SmCo5 and Sm2Co17, and
are commonly referred to as 1:5 and 2:17
Samarium Cobalt magnets are highly resistant to
corrosion and require no special surface
treatment. This makes Samarium Cobalt an
excellent choice for compact designs where high
temperature environments may be present.
