Ferrite magnet
1.Model:Ferrite
2.The ferrite is manufactured with SrO or BaO and Fe2O3 by ceramic process. Because of its cheaper price, and production process is relatively simple, compared with the prices of their products relatively cheap in terms of other magnets.
3. The main raw materials of ferrite magnets is oxide, so, it could not be eroded due to the impact of chemical substances or the environment (except for acid). Therefore, the surface does not need electroplating treatment. It is mainly used in handicrafts, drawing annex, toys, motor, loud speakers.
4.Sintered Ferrite Magnets:
 .Hard ferrite magnets are manufactured by a die pressing followed by sintering process which allows economic production of components in a varied array of sizes and shapes.
 . Ferrite magnets have excellent corrosion resistance and have normal operating capabilities between -40 oC and +250 oC.
