The ferrite magnets from us are made with strontium carbonate and barium carbonate in proportion. After initial pre-sintering, large particles are filtered out, then finely pulverized, ball milled, pressed into shape, and fired at high temperature again…..
A customized High-performance ferrite magnet is a very economical magnet that can be used for automotive sensors, motors, speakers, and micro motors. One deluxe car shall have 20–30 different places which need to be used magnet. We are a professional manufacturer of ferrite magnets and Stator for motors for more than 30 years.

What is the application of ferrite magnets?
Ferrite magnets are used in, for example: speakers, toys, motors, reed contacts, microwaves and industrial magnet systems such as filters and handling systems.
Ferrite magnets are popular because of their stability, affordable price and short delivery time. In addition, they have excellent magnetic properties.
Does your product require a magnet which tolerates high operating temperatures up to 300 °C, while maintaining magnetic force? Then choose permanent ferrite magnets.
In addition to the high operating temperature, these magnets have excellent resistance to corrosion and demagnetisation. Applying a coating of epoxy, for example, ensures clean, dust-free magnets.
