Samarium Cobalt Magnets
SmCo Magnets
SmCo magnets, commonly known as samarium cobalt magnets, are a key member of the rare-earth magnet family, sharing this category with neodymium magnets. Although they are not as powerful as neodymium magnets, SmCo magnets offer two significant advantages: they perform effectively across a broader temperature range and display superior resistance to corrosion. These properties make them particularly valuable in high-temperature environments where durability is crucial.

Choose from our large range of Sm1Co5 magnets and Sm2Co17 magnets.
Sm1Co5 Magnet
Samarium Cobalt (SmCo) magnets, a type of rare-earth magnet, are manufactured by processing metal powders into precision metal components, which include strict controls and convoluted heat treatment cycles.
Sm2Co17 Magnet
There are two different groups of Samarium Cobalt magnets, divided based on their product energy range. The first series of Samarium Cobalt magnets, Sm1Co5, has an energy product range of 15-22 MGOe, and the second series of Samarium Cobalt magnets, Sm2Co17, has a range between 22 and 30 MGOe.
Grades of SmCo Magnets
Samarium Cobalt magnets come in two primary variants, as listed above, each with its own multiple subgrades. These magnets offer various energy products depending on the grade.
- Sm1Co5: Energy product ranges from 15 to 24 MGOe.
- Sm2Co17: Energy product ranges from 22 to MGOe.
Although not as powerful as NdFeB magnets, SmCo magnets excel in high-temperature environments, maintaining their magnetism at temperatures up to 350ยฐC. This makes them ideal for demanding applications like motors and generators in the automotive, aerospace, and manufacturing industries. Additionally, their low iron content gives them superior resistance to corrosion and demagnetisation.
While these magnets are more expensive and brittle, their combination of thermal stability, resistance, and reliability makes them essential in applications where performance and durability are essential.
