Samarium Cobalt Magnets (SmCo)

Explore Our Samarium Cobalt Capabilities

Samarium Cobalt magnets, also known as rare earth magnets, offer the best value when comparing performance and size in high temperature or adverse environments. Samarium Cobalt magnets are higher in cost, but magnetically very strong and typically allow for dimensional reductions. Dura can supply Samarium Cobalt Magnets in stock shapes and sizes, custom, made-to-order Samarium Cobalt Magnets, or we can assist in developing a solution specifically for your application.

Available Grades of Samarium Cobalt Magnets:

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 MEOe.  These ranges allow for balancing cost, magnetic performance, and operational temperature resistance.
