Samarium Cobalt holds its standard property in higher maximum temperatures than neodymium,although its maximum strengh is less. The cost of SmCo material is the most expensive,so SmCo is recommended only when its performance is a high temperature environment is a concern. The characteristics of Samarium Cobalt Magnet
