The elements of Ferrite magnet are ferric oxide、barium、strontium. Ferrite has higher coercive force and higher resistance to be demagnetized and oxidized than other non-rare earth permanent magnets. The biggest advantage of such magnet is their low cost. It is widely used from motors and loudspeakers to toy and crafts etc…

Plastic & Rubber magnets
Plastic & rubber magnets, proved superior to sintered magnets on aspects of
forming ability, size precision, consistence and flexibility, are compounded
of magnetic powder and plastic or rubber material through special technique.
Our company has been engaged in development and improvement of flexible
permanent magnets. Its products, isotropic & anisotropic,carefully tailored
by customers'needs,cover sheeting and roll of all sizes, magnetic stripes of
various crosssections,magnets used for various surface treatments (film
covering, paint spraying). Plastic or rubber magnets are widely used on
micro or special motors,stationery,household appliances,gifts,childrens's
toys and advertising.
