摘要： PROBLEM TO BE SOLVED: To provide a bronze alloy and a sliding member which achieve excellent wear-friction properties and seizure resistance while reducing lead or making lead free. SOLUTION: The bronze alloy has a metallographic structure which has a fine multilayer structure constituted of a layer of α-form copper and a layer of a copper-tin intermetallic compound and includes an eutectoid phase comprising, dispersively precipitated therein, fine metal grains containing at least bismuth (fine bismuth grains, etc.). The proportion of the lamellar eutectoid phase is 10 to 70% by area. From the standpoint of composition, the bronze alloy includes copper and tin as main components and contains nickel, bismuth, and sulfur as additive elements, the nickel content being 0.5 to 5.0 mass%, the bismuth content being 0.5 to 7.0 mass%, and the sulfur content being 0.08 to 1.2 mass%. The tin content preferably is 8 to 15 mass%. The alloy may further contain lead in a proportion of 4 mass% or lower. The bronze alloy is used as a sliding surface of a sliding member (e.g., a hydraulic cylinder block). COPYRIGHT: (C)2010,JPO&INPIT
