Product description
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
