    Permanent ferrite Introduction of

    Permanent ferrite The magnet is made of SrO or BaO and ferric oxide as raw materials and is made by ceramic process. The strontium, sodium and ferrite produced by the permanent magnet part are DM10T, DM20, DM25, DM30, DM33H, DM34H, DM42B, DM43, DM43B and other nine grades and bonded (plastic magnetic) permanent ferrite.

    Permanent ferrite Because of its cheap raw materials, and the production process is relatively simple, so its finished product price is relatively low compared to other magnets. The main raw material of ferrite magnets is oxide, so it is not subject to environmental or chemical substances (except strong acid) and corrosion, so the surface does not require plating treatment. Mainly used in handicrafts, adsorption, toys, motors, speakers and so on.
