Alliance S-22T Sintered SmCo Magnet
Categories: Metal; Electronic/Magnetic Alloy; Nonferrous Metal; Cobalt Alloy

Material Notes: Samarium cobalt magnets were developed in the 1960’s and are still commonly used today because of their excellent very high temperature characteristics. SmCo5 and Sm2Co17 are the two main compositions of this material. They are slightly less powerful than NdFeB magnets, however they are extremely resistant to demagnetization and have the lowest reversible temperature coefficients of all magnets. Because of the high cobalt content, they are costly and their prices tend to be volatile. Plating is typically not required for corrosion protection, however in certain applications they are plated to limit chipping. Most common usage for these materials is in the aerospace and medical industries.
