SmCo Magnets

Samarium cobalt magnets currently mainly have two components, SmCo5 and Sm2Co17. It is a kind of magnetic material made of samarium, cobalt and other metal rare earth materials through proportioning, melting into alloy, crushing, pressing, and sintering. It has a high magnetic energy product, a very low temperature coefficient, and a maximum operating temperature. Up to 350℃, the negative temperature is not limited. When the working temperature is above 180℃, its temperature stability and chemical stability exceed the neodymium iron boron permanent magnet material

●It is manufactured by powder

metallurgy, and the chemical

combination is -SmCo5 and Sm2Co17.

●Extremely hard and brittle

●High resistance to demagneti-

-zation

●Excellent corrosion resistance

●Raw materials are limited, so

the cost is high

●Good temperature stability
