As a composite material, rubber magnet is made by mixing ferrite powder with rubber and finished through extrusion or rolling. Since the material is flexible, the finished or semi-finished product can be cut, punched, slitted or laminated tailed to specific need. It has good resistance to demagnetization and corrosion. Abundant source makes it cheap in price. There are two major types of rubber magnets, isotropic and anisotropic. Isotropic rubber magnet is weak in magnetic property, mainly used in refrigerator, printing, and promotion, while anisotropic rubber magnet is much stronger, thus extensively applied in micro motor and magnetic toys, etc.
