COPPER ALLOY FOR ELECTRICAL AND ELECTRONIC EQUIPMENT, COPPER ALLOY THIN SHEET FOR ELECTRICAL AND ELECTRONIC EQUIPMENT, AND CONDUCTIVE COMPONENT AND TERMINAL FOR ELECTRICAL AND ELECTRONIC EQUIPMENT

摘要

Provided is a copper alloy for electrical and electronic equipment, having reliable and sufficiently excellent stress relaxation properties and having excellent strength and bending workability. Also provided are a copper alloy thin sheet for electrical and electronic equipment and a conductive component and a terminal for electrical and electronic equipment. The copper alloy for electrical and electronic equipment comprises 23-36.5 mass% Zn, 0.1-0.9 mass% Sn, at least 0.15 mass% but less than 1.0 mass% Ni, at least 0.001 mass% but less than 0.10 mass% Fe, and 0.005-0.1 mass% P, with the remainder being Cu and unavoidable impurities. Said copper alloy for electrical and electronic equipment fulfils, by atomic rate, 0.002≤Fe/Ni<0.7, 3<(Ni+Fe)/P<15, and 0.3
