Product Description

We provide Hard Ferrite Magnet, which brittle, but relatively hard. Being prominent exporter, manufacturer, supplier, distributor, and trader in Hong Kong, our Ferrite Magnet is available in industry-specific grade with the promise of uncompromised quality. We offer it in various shapes such as Ring, Cube, Disc, Bar, Arc, and many more as per the client request. This type of magnet is widely appreciated for anti-corrosive properties and thus does not require any specific surface treatment. Consequently, it is suitable for various industrial applications such as DC motors, generators, computer rigid disc drives, annunciators, linear actuators, and many more.
