Sintered Ferrite Magnet/ barium ferrite magnet
General Description:
The hard 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 .The main raw materials of ferrite magnets is oxide ,so ,it could not be eroded due to the impact of chemical substances or teh environment (except for acid ).Therefore ,the surface does not need electroplating treatment .It is mainly used in handicrafts ,drawing annex ,toys ,motors ,loud speakers.
