SAMARIUM COBALT MAGNETS
SmCo magnets with their prominent Anisotropy of Magneto crystal are produced with SmCo5 Co17 composition and started the era of “Rare Earth Magnets”.
The most important disadvantage for SmCo is that Samarium can be rarely found and it is expensive. It is used in drive motors which are needed in robotics, and especially in space crafts and aircrafts which have importance for volume and weight.
