SmCo Discs with Central Holes
Samarium Cobalt SmCo is substitute name of rare earth magnet and provides better temperature coefficients better than neodymium magnets. Because of his good coefficient, it allows fewer variations in magnetic output even when the temperature fluctuates. SmCo outperforms Neodymium at temperatures above +150 Degrees C with an upper limit up to 350 Degrees C.
Where there is high temperature and external demagnetizing forces exist such as in motors and generators, these magnets provides variety of applications, thus makes it great choice.
SmCo also provides superb choice for different temperature applications, such as sensors and it require stable magnetic field. It is also used aerospace, automotive and military applications.
Offering fantastic corrosion resistance to water, where its structures have little free iron. However, SmCo’s brittle in nature material makes it a sensitive magnet that requires protection and safety glass is the safest bet to get protective.
SmCo magnets have made in straight through holes or countersunk holes. These ring magnets have higher presence coefficients compared to disc magnets are the same outer dimensions. The magnetic pole on the countersunk face is stated because, when applying the rule of unlike Poles attract, a South countersunk face magnet will attract only to a North countersunk faced magnet (although any countersunk ring magnet can be used to attract to mild steel).
