    摘要: The present invention relates to a Cu-based sintered alloy which has a composition containing: Zn: 10-40%; Al: 0.3%-6% oxygen: 0.03-1%; any one selected, as an additional element from the group including at least one of Fe, Ni and Co: 0.1-5%, Mn: 0.1-5%, Si: 0.1-3%, and at least one of W and Mo: 0.1-3%; and the remainder including Cu and inevitable impurities. The alloy is superior in wear resistance particularly in air at temperatures ranging from the ordinary temperature to 400.degree. C., has high strength and high toughness, and further excels in the uniform temporal change characteristics with associated members, as evaluated by its friction coefficient. The invention relates also to parts for automotive equipment made of this Cu-base sintered alloy, such as synchronizer rings for transmission, valveguides for engines, bearings for turbo-chargers and so forth.
