Segment Samarium Cobalt SmCo Magnet

SmCo Magnets

SmCo magnet is composed of Samarium, Cobalt, and a few transition metals.

SmCo magnets are high performance, low temperature coefficient rare earth permanent magnets. SmCo alloys exist that can be used in high temperature environments of up to 350 degrees Centigrade.

Generally, SmCo magnets must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on SmCo magnet using carbide tools, but this won't yield a smooth surface finish.

The Standard tolerances for SmCo magnet are +/- 0.1mm for ground dimensions, but stricter tolerances are possible if specially required.
The corrosion resistance of SmCo magnets is considered good. Although Surface coating or plating is not generally required for SmCo magnets, all kinds of surface coating are also available, like Nickel, Zn, Ni-Cu-Ni, Gold, Silver, Sn, Chrome, ABS , Rubber, PTFE(Telfon), stainless steel and Epoxy coating etc.

We provides two types of SmCo magnets:1-5 type and 2-17 type respectively with various grades.
