Sintering Ring SmCo Magnets

Sintering Ring SmCo Magnets  are circularly made by strict powder metal technology and heat processing. 

SmCo Ring Magnet

This kind of magnet conveys samariam for 35%, cobalt for 60%, element Fe and Cu. Through altering proportioning of
compositions and circulation of sintering and heating, we can make two materials_ 1: 5 and 2: 17. The difference lies in energy product, temperature coefficient and coercivity. The most common material, 2: 17, has better property and lower temperature coefficient, but it is more expensive and should be magnetized in high magnetic field.
Americans invented SmCo5 and SmCo17 in 1965 and 1972. This invention drives a high wave to study and explore new permanent magnetism, and promote the development of the materical rapidly. This material is produced by powder metallurgy, and its specialty is its magnetic stability, temperature resistance, and excellent resistance of corrosion. Its max magnetic energy prduct is 15~30MGOe which is 3~5 times to AlNiCo magnets. Its intrinsic coercivity is over 25kOe, and its highest working temperature is 350 C. SmCo magnet is very suitable for manufacture the products with high-performance like magnetic motors and other applied products requiring high working temperature.  Strong Ring SmCo Magnets
