Product Description

Samarium Cobalt (SmCo) disc magnets for magnetic couplings

Product Show

Samarium Cobalt (SmCo) 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.

Materials:  Smarium and cobalt and other rare-earth elements
Shape: Disc;
            or Block, Cylinder,Ring, Countersunk, Segment, Trapezoid, Irregular shapes and more.
            Custom design
Size: Customized
Alloy series: SmCo5, Sm2Co17
Performance: high performance; low temperature coefficient; high working temperature-350°c; it is difficult to be eroded and oxidized
Applications: Electronic magnetron, magnetic transmission, magnetic treatment, magnistor, sensor, etc.
