浙江省东阳市剑华磁业有限公司

Permanent ferrite magnets usually refer to sintered permanent ferrite magnets, which belong to the second generation of permanent magnet materials. They have the characteristics of high resistivity, good stability, and strong resistance to environmental changes. The raw materials are abundant and cost-effective, suitable for large-scale production. They are key electronic materials for components such as electroacoustic devices and permanent magnet motors. The company currently produces a total of 20 grades of permanent magnet ferrite magnets with complete specifications, forming a relatively complete product cluster that can meet the diversified market demands of many application fields.
