This sample is a samarium cobalt disk magnet, the diameter is 20mm, the thickness is 5mm. The magnetization direction is thickness. The SmCo magnet is no coating, so the surface color usually is natural color of samarium cobalt material. But if you wanna coating for product, you can choose the coating or spray paint according to the demand, and we can customize for you. samarium cobalt magnet is one of rare earth permanent magnets, currently mainly composed of SmCo5 and Sm2Co17.
Samarium cobalt magnets have good market value because samarium cobalt has very high coercivity, good temperature stability (up to 350 degrees), strong corrosion and oxidation resistance. Its temperature stability and chemical stability are more than NdFeb permanent magnet material.
Therefore, it is widely used in aerospace, national defense and military components, communications, automobiles and electronic instruments, electricity meters, water meters, sensors, ovens, hangers, mechanical equipment, magnetic fixture, FPC magnetic carrier, carrier plate, magnetic tray, etc.
