Superior resistance to high temperature, excellent resistance to corrosion, no coating is needed for surface protecting

SMCO magnet is high property product. It can anti-high temperature, anti-corrosion. SMCO magnet is suitable for machines with high magnetic requirement and good for strict working environment requirement.

Samarium Cobalt (SmCo) magnets are made by a sintering process and exist in two forms. The first is Sm1Co5 (SmCo 1:5) and this has a maximum energy product of between 14 and 24 MGOe. The second, and more common, form is Sm2Co17 (SmCo 2:17) and this has a maximum energy product of between 22 and 32 MGOe. The main Sm2Co17 alloy is around 35% Samarium (Sm) and 60% Cobalt (Co) with the balance being from varying amounts of Iron (Fe), Copper (Cu), Hafnium (Hf)
