Samarium cobalt magnet, also known as Samarium cobalt magnetic steel, Samarium cobalt permanent magnet, Samarium cobalt permanent magnet, rare earth cobalt permanent magnet, etc. It is a magnetic material made by mixing samarium, cobalt, and other rare earth metals into alloys, crushing, pressing, and sintering. It has a high magnetic energy product, extremely low temperature coefficient, and a maximum working temperature of 350 ℃, with no negative temperature limit. When the working temperature is above 180 ℃, its maximum magnetic energy product, temperature stability, and chemical stability exceed that of neodymium iron boron permanent magnet materials.
Samarium cobalt magnets have strong corrosion resistance and oxidation resistance; So it is widely used in aerospace, national defense and military industry, microwave devices, communication, medical equipment, instruments, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes, etc.
