Countersunk SmCo Magnets – Samarium Cobalt SmCo 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.

Samarium Cobalt, SmCo, is the alternative Rare Earth magnet to Neodymium.

SmCo has better temperature coefficients than Neodymium allowing less variation in magnetic output over temperature fluctuations. SmCo outperforms Neodymium at temperatures above +150°C (with an upper limit of +350°C) and can be used at temperatures nearly as low as absolute zero (-273°C).

SmCo is a great choice for applications where high temperatures exist and where high external demagnetising forces exist, such as in motors and generators.
