Samarium Cobalt magnets custom engineered for your application…

Many grades of Samarium Cobalt exist to support a variety of industrial and commercial applications.  The range of Samarium Cobalt Magnet grades is typically 16 to 32 MGOe.  These ranges allow for balancing cost, magnetic performance, and operational temperature resistance.

SmCo Rare Earth magnets are very resistant to corrosion and do not normally require any surface treatment.

Although most commercial magnets are anistropic, which means they have a preferred direction of magnetization, various pole configurations can be achieved without conflicting with a Samarium Cobalt Magnet’s orientation.

Samarium Cobalt magnets manufactured by Dura Magnetics are compliant with Intellectual Property Rights, Environmental Restrictions, and Conflict Mineral usage.

  • DFARS Compliant
  • Dodd Frank Wall Street Reform Act (Section 1502)

SmCo Magnets are very strong and brittle, requiring appropriate handling and packing to ensure safety and prevent damage.

Samarium Cobalt Magnets are typically manufactured by a powdered metallurgical process utilizing rigid steel or rubber molds.

DFARS & ITAR Compliance

Limited availability of Defense Federal Acquisition Regulation Supplement (DFARS) compliant material can make small magnet production runs costly. However, we stock various grades at our U.S. facility, enabling us to provide cost-effective, DFARS-compliant magnets for all customers if needed, regardless of project size or requirements.
