SmCo Magnets made of MPCO
Rare-Earth Permanent Magnets for High Temperature Applications
Permanent Magnets in Different Shapes and Various Coatings
Samarium-Cobalt magnets made of MPCO have particularly high coercivities with simultaneous high saturation polarization and excellent temperature and corrosion stability.
Benefits:
Suitable for high temperature applications (depending on alloy up to max. 350 °C)
High corrosion resistance against aggressive media
Usually no coating necessary
Low decrease of magnetic properties with increasing temperature due to high Curie temperature
SmCo magnet is composed of Samarium, Cobalt, and a few transition metals. SmCo magnet is high performance, low temperature coefficient rare earth permanent magnet, and could keep their performance under the maximum working temperature up to 350 degree centigrade.
Manufacturing Process
Samarium, Cobalt, and a few transition metals will be made into the SmCo powder, then fine SmCo powder will be compacted in a die and sintered, fusing the powder into a solid material. There are 2 forms of pressing: die pressing and isostatic pressing. Sintered parts normally need some finish machining in order to meet final tolerances.
Machining & Tolerance
Generally, SmCo magnet must be machined using diamond-grinding techniques. Sometimes, machining operations may be performed on SmCo magnet using carbide tools, but surface finishes thus obtained may be less than optimal. Superior Strong Industrial SmCo Square Magnets YXG-28H
The Standard tolerances for SmCo magnet are +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required.
Surface treatments
The corrosion resistance of SmCo magnet is considered good. Although Surface coating or plating is not generally required for SmCo magnet, all kinds of surface coating are also available, like Nickel, Zn, Ni-Cu-Ni, Gold, Silver, Sn,Chrome, ABS coating, Rubber coating, PTFE(Teflon) coating, stainless steel case and Epoxy coating etc.
