Pressing Bonded SmCo
Pressing Bonded SmCo magnet is made by mixing the SmCo magnetic powder with polymer materials, then through the mold to press and form the various magnet shapes.(We can get the higher-performance anisotropic products by applying the magnetic field orientation during the molding proecess).
The Bonded SmCo magnetic rod disc ring magnets not only has high accuracy, various shape, characteristics, but also the strong corrosion resistance, generally without surface treastment; as well as the high temperature stability.
