Samarium Cobalt Discs (SmCo)

Samarium Cobalt (SmCo) disc magnets have a very high resistance to demagnetization and outstanding temperature stability. This makes them a great choice for many situations where high temperatures are a consideration, for example in high performance motors, computers, spacecraft, aircraft engines, precision drilling equipment. These magnetic discs are very strong magnets. They belong to the rare earth magnet group.

This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More
