Copper Powder

产品描述PRODUCTION DESCRIPTION：

Copper is a very common metal friction material filler, its good heat transfer coefficient contributes to transfer the heat generated from frictional touch face to in-part of the friction products, thus to control of the temperature of the brake components. The chemical composition and micro-structure of the fiber make copper an ideal material for use in friction materials of high performance and high duty levels. Copper also has a relatively low Mohs scale of hardness, which contributes to anti-friction in high temperature. In Europe, brass will be widely used in brake pads, especially in high-class brake pads friction materials, 5%-8% will be much more proper.
