SmCo Magnets

Products: Sintered SmCo Magnets

Smco magnetsSamarium Cobalt (SmCo) magnets offer designers a tremendous combination of extremely high magnetic properties, outstanding thermal stability and excellent corrosion resistance. 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 SmCo5 and Sm2Co17, and are commonly referred to as 1:5 and 2:17 materials.

Features of SmCo Magnets

  1. SmCo magnet is high performance, low temperature coefficient permanent.
  2. Its biggest advantage is high working temperature-300 degree centigrade, this makes Samarium Cobalt an excellent choice for compact designs where high temperature environments may be present.
  3. Good corrosion resistance and no need to be coating, because it is difficult to be eroded and oxidized.
  4. Grinding and slicing can be operated into the desired shape and size.

Application of SmCo Magnets :

SmCo magnet is widely used in motors, watch, transducers, instruments, positional detector, generators, radar, etc.


Due to their extremely high magnetic strength and brittle nature, SmCo magnet parts must be handled very carefully to prevent injury to personnel and damage to the magnets. Receiving and assembly personnel must be pre-warned about the dangers of handling these magnet parts.
