所谓复合磁钢就是以橡胶、塑料等材料作为粘结剂将磁性粉末粘结而成的。复合磁钢的磁性比通常的烧结磁钢、铸造磁钢差,其优点是适合难以制作的小型、薄型、复杂形状的产品。 The so-called composite magnet is a rubber, plastic and other materials as a binder made of magnetic powder bonded together. The magnetic properties of the composite magnets are lower than that of ordinary sintered magnets and cast magnets, which has the advantage of being suitable for small, thin and complex shaped products that are difficult to manufacture.
