Send Inquiry
The chemical composition of magnets is iron oxide, barium and strontium elements. SrO-6 (Strontium Carbonate), Fe2O3 (Ferrite Oxide) or BaO-6 (Bariumar Bonate) (Fe2O3).

It is manufactured under a powder metallurgy process and various types of: Isotropic Barium Magnet and Anisotropic (Strontium or Barium).

Ferrite magnet is most widely used and have won wide acceptance. Due to it is good resistance to demagnetization, excellent corrosion resistance and the biggest advantage of such economic cost.

The Ferrite magnet is widely from most types of DC motors, loudspeakers, Magnetic Instruments, magnetic Holders and automotive sensors. The magnetizing in various patterns can be made depending upon the usage, various sizes and shapes can be made depending according to the customer's demand.
