Samarium Cobalt Disc Magnets

Because Neodymium magnets do not perform well in high temperatures, the Samarium Cobalt disc magnets are often now used in high-performance motors. Accelerometers and gyroscopes - in aircraft, marine and spacecraft – as well as downhole drilling and many precision control systems take advantage of the temperature stability of Samarium Cobalt magnets.

Samarium Cobalt Disc Magnets

While hard and brittle due to the sintering process that occurs during manufacturing, Samarium Cobalt magnets have the highest resistance to demagnetisation and outstanding temperature stability.

The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
