Samarium Coalt(SmCo) magnets offer designers a tremendous combination of magnetic properties,excellent heat resisitance and excellent resistance to corrosion.As part of a group of rare-earth permanent magnets,Samarium Cobalt(SmCo) magnets typically fall into two familes of materials. They include rare earth SmCo5 Sm2Co17 ,and are commonly known as 1:5 and 2:17 materials.
Samarium Coalt magnets are very resistant to corrosion and require no special coating.Samarium Cobalt makes it an excellent choice for a compact design where the high temperature environmengte may be present.
Samarium Coalt to keep a costant property of maximum temperatures than neddymium,although its greatest strength is lower,SmCo materials prices is the most espensive,so SmCo is recommended only when its performance is a high temperature environment is a concern.
