Features
Strong Ring SmCo Magnet is the alternative Rare Earth magnet. It is often used in aerospace, automotive and military applications. It is usually weaker than NdFeB Neodymium at room temperature.
Samarium Cobalt SmCo is capable of use in extremes of cold and heat. It also has very high coercivity making it ideal for high temperature motor applications.
Samarium Cobalt also has extremely good temperature coefficients making the magnet output very stable with small changes in temperature. It is very popular in mission critical sensing applications.
