Bonded Ferrite

Bonded Ferrite Magnet is a combination of ferrite powder and binder, which is usually rubber material of plastic materials. According to the binder material, it is also called Rubber magnet of Plastic Magnet. It can be supplied in both isotropic and anisotropic form.

Rubber Magnet can be extruded or

calendered into long or thin shape. It is flexible and has excellent process properties which is suitable to be produced into different shape and dimension by cutting, punching, drilling and bending, etc.

Plastic Magnet is made by injection molding, It is ideal for applications where a low cost Magnet needs to be combined with complex form precisely.
