Description
Samarium cobalt magnets (SmCo) are classified into SmCo5 and Sm2Co17 based on their composition. It is a magnetic material made by blending samarium, cobalt, and other rare earth materials into alloys, and then grinding, molding, and sintering them. It has a high magnetic energy product and extremely low temperature coefficient, with a maximum working temperature of 350 ℃ and no negative temperature limit. When the working temperature is above 180 ℃, its maximum magnetic energy product, temperature stability, and chemical stability exceed those of neodymium iron boron permanent magnet materials. Has strong corrosion and oxidation resistance
