摘要： PROBLEM TO BE SOLVED: To produce a sintered friction member by means of a single sintering stage while saving labor and time and also to improve the joining strength between a ferrous base material and a coppery friction material by enabling the simultaneous sintering of a ferrous powder and a coppery alloy powder. SOLUTION: This sintered friction member consists of a ferrous base material 1 and a friction material 2 composed of a Cu-Ni alloy formed integrally with the base material 1 and is obtained by subjecting a ferrous powder and a Cu-Ni alloy powder to simultaneous compacting and simultaneous sintering. This Cu-Ni alloy contains Ni by 10 to 70 wt.%. Because the Cu-Ni alloy, containing Ni by the prescribed amount or more, is adopted as a friction material, the coppery friction material and the ferrous base material can be subjected to simultaneous compacting and simultaneous sintering and formed into the sintered friction member. Further, in the joining surface between the ferrous base material and the coppery friction material, the ferrous powder and the Cu-Ni alloy powder are tangled together sufficiently, and as a result, the joining strength between the ferrous base material and the coppery friction material can be satisfactorily improved.
