High temperature samarium cobalt permanent magnet alloy

　　High temperature samarium cobalt permanent magnet alloy:

　　:17 type SmCo Sm2Co17 permanent magnets material has excellent temperature stability (Curie temperature, temperature coefficient of remanence, coercivity temperature within the coefficients are significantly better than the other rare earth permanent magnets' materials) good corrosion resistance and high magnetic energy.

　　In recent years, with the further development of weapons demand, it proposes high using temperature, high stability and long life requirements for use of permanent magnets' material. For a long time, developed countries invested a lot of money to carry on deep research to improve the temperature stability, magnet and rare-earth permanent magnets' reliability, with the improvement of aerospace and military technology, it is required that temperature of permanent magnets material can be within 400 and 500 degrees Celsius range, and have a high performance and stable operation, Sm2Co17 type permanent magnets alloy has become the preferred material.
