The use of high purity aluminum for cooked from raw materials processing, can be used for all kinds of friction materials, stabilize the coefficient of friction and reduce the role of wear. Friction in the process of melting the aluminum absorbed a lot of heat; heat played a role in Al relatively soft metal used in friction materials Gu difficult injury, the injury was, to extend the life of the brake system. In addition the proportion of lighter aluminum, to reduce the weight of materials, aluminum in the friction material on the surface is very uniform distribution, the friction material on the surface appearance beautiful.
