Samarium-cobalt magnets, also known as samarium-cobalt magnets, samarium-cobalt permanent magnets, rare earth cobalt permanent magnets, etc., are made of samarium, cobalt and other metal rare earth materials through proportioning, melting into alloys, crushing, pressing, and sintering. A magnetic material with high magnetic energy product and extremely low temperature coefficient. The maximum working temperature can reach 350℃, and the negative temperature is not limited. When the working temperature is above 180℃, its temperature stability and chemical stability exceed neodymium iron Boron permanent magnet material.

        Samarium cobalt magnets (SmCo) currently mainly have two components: SmCo5 and Sm2Co17. Samarium cobalt magnets have strong corrosion resistance and oxidation resistance, so they are 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 and other fields.

       The production process of samarium cobalt magnets: ingredients → smelting ingots → powder making → profiling → sintering and tempering → magnetic inspection → grinding processing → pin cutting processing → finished product.
