nian tian magnets - permanent magnet ferrite is SrO or BaO and Fe2O3 as raw materials, through the ceramic process and manufacture. Because of its raw materials are cheap, and the production process is relatively simple, so the product price is relatively low compared to other magnet. Ferrite magnet is the main raw material for oxide, it is not affected by environmental or chemical substances (except outside the influence of strong acid ) and corrosion, the surface does not need plating processing. Mainly used in handicrafts, suction attachment, toys, motor, loudspeaker.

Production process:

Ingredients: burn-in: broken / milling / milling / dry pressing magnetic field molding / dry pressing / wet pressing magnetic field molding -----> Sintering / machining / test / packaging
