SMCO 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.
