烧结钕铁硼（Sintened NdFeB）

Permanent magnet materials and devices provider

钕铁硼具有极高的磁能积和矫颃力，同时高能量密度的优点使钕铁硼永磁材料在现代工业和电子技术中获得了广泛应用，从而使仪器仪表、电声电机、磁选磁化等设备走向高性能、小型化、轻量化、薄型化。

从1984年开始批量生产NdFeB，本公司NdFeB具有高能积、高一致性、低失重、优良耐腐蚀性、良好的亲胶性等特点。主要的表面处理方式有镀锌、镍、银、金、磷化处理或电泳处理（环氧树脂）。

NdFeB magnets are widely applied in modern industry and electronic technology because of its high energy force,high coerdve force and high energy density The application of NdFeB makes the instruments. electro-acoustic components, electric motors, magnetic separations and other magnetization equipments achieve higher performance, smaller size and lighter weight.

We have been producing the NdFeB magnets in mass production since 1984 The NdFeB magnets made by Westmag have Such characteristics: high-energy. high consistency, low weight loss and good corrosion resistance and so on The main surface treatments are zinc. nickel, silver, gold. phosphating and electrophoresis (epoxy).
