is also known as samarium cobalt magnet, samarium cobalt permanent magnet, samarium cobalt permanent magnet, rare earth cobalt permanent magnet, etc. It is a magnetic material made of samarium, cobalt and other metal rare earth materials through proportioning, melting into alloys, crushing, pressing and sintering. Up to 350 ℃, the negative temperature is not limited, when the working temperature is above 180 ℃, its temperature stability and chemical stability are higher than NdFeB permanent magnet materials.
One of the rare earth permanent magnets, there are mainly two components: SmCo5 and Sm2Co17.Large magnetic energy product, reliable coercivity and high temperature resistance. It is the second generation of rare earth products.
Samarium cobalt magnet (SmCo) has stronger anti-corrosion, rust-proof and high-temperature resistance than NdFeB magnets. SmCo magnets are modified by alloying, which will completely change the world’s rail transit mode.
It has strong corrosion resistance and oxidation resistance; so it is widely used in aerospace, defense and military industry, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes Wait.
