Cobalt Samarium (SmCo)

Home » Products » SmCo Magnets

Samarium cobalt permanent magnets can be divided into two categories, SmCo5 and Sm2Co17. According to the composition, SmCo5 is the first-generation rare earth permanent magnet material, while Sm2Co17 is the second generation. Its main characteristics are high magnetic properties, good temperature resistance and great corrosion resistance.
