Abstract：The mechanical properties， friction properties and friction surfaces of copper-tin alloy friction materials for vehicle braking were characterized， and the effects of different copper-tin alloy additions on the performance of friction materials were analyzed. The results show that the density of friction materials gradually increases， and the pH value remains almost unchanged， the hardness first increases and then decreases， compressive stress first decreases and then increases， and shear strength changes little with the increase of Cu-Sn alloy content. With the increase of brake pressure， the friction coefficient of all samples decreases. A relatively complete friction film is formed on the surface of the sample with 15% （mass percent） copper-tin alloy， but the friction film peels off to some extent.
