Samarium Cobalt

ABOUT SAMARIUM COBALT

Samarium cobalt is a rare earth material made by a powder metallurgical process.  Manufactured using binders such as epoxy, samarium cobalt magnets are inherently very brittle.  Users are discouraged from grinding material because the dry remnants are a fire hazard.  Some of the advantages of using samarium cobalt is that it provides excellent temperature stability and as well as excellent corrosion resistance.  Because of this, typically coating or plating is not required. Samarium cobalt is excellent for operating in harsh environments where it will be exposed to the elements as well as high operating temperatures.

Yunsheng offers a limited selection of the most popular material grades.

Samarium cobalt excels in harsh environments - common applications include marine, and aerospace.
