Magnetic materials are fundamental functional materials of electronic industry. As important parts of magnetic materials, hard ferrite materials play a heavyrole in electronic industry, electronic information industry, car industry, motorcycle industry etc. meanwhile, they are also widely used in medical treatment, mining and metallurgy, industrial automation, oil energy industry and civil industry. Ferrite Magnet, Ferrite Magnets, bonded ferrite magnet, barium ferrite magnet, hard ferrite magnet, sintered ferrite magnet, bonded ferrite injection magnet

Our main products includes :hard ferrite arc or segment, ring magnets, rectangular magnets, ferrite power etc. Which have the following advantages: high coercive force, high electric resistance, long-time stability, and economical price. Meanwhile, we can manufacture new tools according to the customers` demand. ferrite magnet, ferrite magnets
