Abstract
A sintered friction material includes a copper alloy base and hard particles. The copper alloy base includes copper and at least one of, and preferably both, Zn and Ni within a total range of 5 to 40 wt % of the copper alloy base. The hard particles are uniformly dispersed in a matrix formed by the original composite copper alloy powder constituting the base, in a content amount within a range of 10 to 30 wt % of the friction material.
