SmCo Magnets

Category: rare earth magnets/ Samarium-Cobalt magnets/ SmCo magnets

Advantages: highest coercive force; highest working temperature; good temperature stability

Disadvantages: price is too expensive

The same as neodymium magnets, Samarium Cobalt magnets are also rare earth permanent magnets, which short as SmCo magnets. It is an alloy of Samarium, Cobalt and other rare earth elements. SmCo permanent magnets successfully developed in the year 1970, it is the second strong rare earth permanent magnets, which have the highest BH(max) and Coercivity.

It’s working temp. can up to 350 degrees, no limit below 0 degrees. Its temperature stability and chemical stability are all better than neodymium permanent magnets for working temp. that more than 180 degrees. So compared with neodymium magnets, SmCo magnets are more suitable to work under high temperature, and used to make high property permanent magnetic motors, and used to make the magnets application products which suit for a very special working environment.  There are two component of for SmCo magnets,  Sm1Co5 magnets, and Sm2Co17 magnets.
