High Quality D15*3mm SmCo Permanent Magnet


Specifications

1)Constitution: 35% Sm, 60% Co and 5% Fe & Cu
2)SmCo Magnet(Samarium Cobalt magnet) has superior resistance to high temperature(max temp 
reaches 350 degree centigrade).When working at above 180 degree centigrade, its maximum energy
product BH and temperature stability are superior than NdFeB magnet.
2)Excellent resistance to corrosion, no coating is needed for the surface protecting.
3)SmCo is suitable for machines with high magnetic requirements and good for strict working environment
 requirements

4)All sorts of SmCo are used in the electronic magnetron, magnetic transmission, magnetic treatment,
magnistor, etc
5)Certification: ISO 9001 :2008 quality system.
6) High energy ranging from 14MGOe to 30MGOe
7) Reliable coercive force
8) With the best temperature characteristics in rare earth material family.
SmCo magnets 
Sintering SmCo magnets are circularly made by strict powder metal technology and heat processing. 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.
