Custom Samarium Cobalt Disc Magnets
Samarium Cobalt (SmCo) disc magnets are powerful magnets rare earth magnets composed of samarium and cobalt. They are commonly used in high performance motors, magnetic couplings and magnetic separators. These are brittle magnets and are prone to cracking and chipping. Samarium magnets can be used for high temperature applications where neodymium will not work.

SmCo Magnets – SmCo5 & Sm2Co17
Samarium Cobalt (SmCo) disc magnets are the second generation of rare earth permanent magnets, it is made of samarium, cobalt and other rare earth metal. Bearheart can provide SmCo5 and Sm2Co17 magnets in various shapes.
Production Process of Samarium Cobalt Permanent Magnet:
Powder process→ Pressing→ Sintering → Magnetic property test → cutting → finished products
Samarium cobalt materials are commonly processed under un-magnetized circumstances, with diamond grind wheel and wet fine grinding, which is necessary. Because of the low ignition temperature, samarium cobalt must not be dry completely. Just a small spark or static electricity in production can easily trigger a fire, with extremely high temperature, which is hard to control.
Samarium Cobalt Disc Magnets Application:
SmCo permanent magnets have a strong resistance to corrosion and oxidability, which are widely applied to aviation, and aerospace, national defense and military industry, microwave components, communication, therapy equipments, instruments, apparatus, various kinds of magnetic transmission devices sensors, magnetic processer, motor and magnetic lifting machines.
