Sintered Hard Ferrite magnet
Ferrite magnet is one kind of the most widespread permanent-magnet material£¬and it is manufactured by powder metallurgy. mainly divides into the (Ba) and (Sr) two kinds with anisotropy and isotropic£¬and is one kind of permanent-magnet material which is not easy to degauss and corrode, the highest operating temperature may amount to 250¡æ. It is rigid and crisp can be cut and process with diamond-sand. It is mainly used for permanent magnetic motors and speakers.
Sintered Ring Ferrite Magnets With Multiple Poles
What our company produced presses the Multiple-Poles ferrite magnetic ring of radial dry, used in fields such as synchronous motor, miniature motor, water pump motor, toy motor, transducer, electronic instrument and etc.
Sintered NdFeB Magnet
At present, Sintered NdFeB is one of the strongest magnet materials available. It¡¯s high residual induction (Br), high intrinsic Coercive force (Hcj) and high Energy Product (BH), makes it suitable for servo motors, disk brushless motors, stepping motors, IT industry, MRI, and audio products. For NdFeB, its surface is usually treated with some special methods. The surface treatment method include Zinc, Nickel, Tin, Silver, Gold plating, Phosphor and Spray Epoxy Resin etc.
