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. There are three different manufacturing processes: sintered SmCo magnet, bonded SmCo magnet, and injection molding SmCo magnet.
