Ferrite Magnets

Product Specification

Ferrite Magnets are made by sintering a mixture of iron oxide and strontium oxide or barium oxide. Because different producing processes, it is including Isotropic and Anisotropic types. The isotropic magnet made by press and die casting, and magnetic field alignment not applying to, after sintering, the magnet can be magnetized in any direction. Due to short producing lead time and low price, they are widely used in electronics and engineering industrial products.
[part] The anisotropic magnets also made by press and die casting, but they have to apply magnetic field alignment before sintering, then magnetized in the same direction, and not be able to change it, due to the magnetic flux along the same direction, they have more powerful magnetic force than isotropic ferrite magnets.
Applications:
They are suitable to apply in the following industries: Electronic product, Toy, Industrial equipment, Furniture, Stationary, Giftware...etc. Examples of applications are Micro motors, Dynamos, Convertible Motors, Magnetic Separators, Bell & Buzzer, Magnetic Instrument, Fasteners & components, Sensor components, Adjustment of DY Core, Health Therapy, Loudspeakers, Door Catches, Water Pump, Auto Parts, Clock Parts, Magnetic Holders, Others...etc.
