Abstract：The microstructure， compression properties and dry friction and wear properties of copper-based powder metallurgy friction materials adding Ni and β-SiC were studied. The results show that Ni and Cu have been alloyed at sintering temperature of 800 ℃， Ni and β-SiC can effectively stabilize the friction coefficient， thus improve the performance of dry copper-based powder metallurgy friction material. The uniformly distributed β-SiC can effectively improve the wear resistance of the material.
