Sintered SmCo Magnet

Rare-earth Sintered SmCo Magnet

The sintered SmCo (Samarium Cobalt) magnets are a type of rare-earth permanent magnet produced in the sintering process. These materials are breakable, so they need to drill or chip to enhance outstanding magnetic properties.

With maximum energy of 30 MGOe, the sintered SmCo magnets can withstand high temperatures, curie temperatures, and minimum temperature induction coefficients. They also have excellent resistance to corrosion, which makes them ideal for machines requiring high magnetic and strict working conditions.

Dailymag sintered SmCo magnets are available in arcs, blocks, discs, and many custom shapes. Most of them do not require any coating as they are corrosion-resistant. But if you really need any coatings for a particular use, we have available epoxy, tin, nickel, zinc, Teflon, etc.

Two Series of Sintered SmCo Magnet

Dailymag sintered SmCo magnet is identified as SmCo 1:5 and SmCo 2:17. The SmCo 1:5 composition means one Samarium atom and five Cobalt atoms. While the SmCo 2:17 means two Samarium atoms and 13-17 Cobalt atoms. These two compositions both provide very high magnetic characteristics and thermal stability.
