Samarium Cobalt magnets are made by a sintering process and exist in two forms. The first is Sm1Co5 and this has a maximum energy product of between 14 and 24 MGOe. The second, and more common, form is is Sm2Co17 (SmCo 2:17) and this has a maximum energy product of between 22 and 32 MGOe. Samarium Cobalt (SmCo) magnets are slightly weaker than Neodymium (NdFeB) magnets but work over a much wider temperature range (they can work from cryogenic temperatures up to +250 or +300/+350 degrees C; the SmCo26 is rated to +300 degreec C), have superior temperature coefficients and have greater corrosion resistance. We offer 29 grades of sintered SmCo and 7 main grades of bonded SmCo. SmCo26 (a 2:17 variety) is the most commonly used grade.

Samarium Cobalt (SmCo) is suitable for applications such as pump couplings, sensors, loudspeakers, generators, guitar pick-ups, motors, sump plugs, high temperature applications, wide temperature range applications and for use in corrosive (e.g. water, oil) environments, marine applications, automotive, aerospace and military applications.

We also offer made-to-measure sintered and bonded SmCo magnets. Please contact us for more details.
