Arc SmCo magnet 1)element: 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)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)In the electronic magnetron, magnetic transmission, magnetic treatment, magnistor, etc you can usually find Arc SmCo magnet.
