Samarium cobalt magnets/smco magnet Sm2Co17
Product Description
Samarium cobalt magnets/ smco magnet Sm2Co17
SmCo magnet magnets are ideal component sepecially in applications where temperature changes
across a broad range or enviroment is corrossive. The cost of SmCo material is the most expensive,
so SmCo magnet is recommended only when its performance is a high temperature
environment concerned.
The advantages of SmCo Magnet:
SmCo magnet is one kind of rare earth magnet with a high percentage of samarium,
which is relatively stable against temperature change
SmCo magnet has high energy and excellent coercive force, this material is ideally compact
and suitable to highly efficient machinesand components, and widely used in application
in which higher operation temperature, higher corrosion and oxidation resistance are crucial.
SmCo magnet has the best temperature characteristics in rare earth material family.
Shape of SmCo Magnet: Disc, Ring, Block, Segment, Cylinder, Trapezoid, Customized Design
