Ferrite Magnets
Our company has been widely acclaimed for providing our clients with this extensive range of Ferrite Magnets that has been extensively composed of best quality iron and barium or strontium oxides. The offered magnet is hard in composition and can be easily categorized by high normal & intrinsic coercive force. In addition to this a rather low residual induction and are virtually free from the effects of a self-demagnetization. Offering a corrosion free ferrite, it is also used for treatments as it posses a comparatively high electric resistivity.
