Samarium Cobalt Magnet |
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 Sm1Co5
and Sm2Co17 and are referred to as 1:5 and 2:17 materials. Samarium cobalt
typically offers high energy products with excellent coercive (resistance
to demag) forces.
This makes samarium an excellent choice for small, compact designs where
high temperature environments may be present.
Characteristics
* High energy products
(up to 32 MGOe)
* Good mechanical characteristics
* More brittle than Nd
material
* Can withstand higher
temperatures than Nd
* Exhibit good corrosion
resistance thus requiring no surface treatment
