Sintered ferrite is a sintered magnetic material. The main components are SrO or BaO and Fe2O3, according to the different processing technology, can be divided into isotropic and anisotropic. Isotropic magnets have a lower performance, but it can be magnetized by each side of the magnet; the anisotropic magnets have higher performance, but they can only be obtained by pre designed magnet dimensions.

Our main magnet for loudspeaker,Electronic induction, microwave oven, three-dimensional motor, instrument and equipment, mechanical equipment, art and toys etc..

Features: 

1)、 high working temperature

2)、Anti demagnetization capability,

3)、Not easy to oxidation
