Abstract

PURPOSE: To provide the subject alloy with excellent electric and heat conductivity, heat resistance and spring characteristics by incorporating specific amounts of Sn to a Cu-Zn alloy having specific compsn.
CONSTITUTION: The compsn. of the copper alloy for electronic parts is constituted of, by weight, 3W20% Zn, 0.1W4.0% Sn, or furthermore of 1W15% Ni and the balance Cu with inevitable impurities. If necessary, one or more kinds selected from the group of 0.001W2.0% Cr, Co, Zr, Be, As, P, Pb, Si, Ti, Mn, Mg, Fe and Al are furthermore incorporated thereto as the secondary components. Said copper alloy has more excellent strength, solderability, stress relaxation characteristics, corrosion resistance and SCC resistance than red brass which is the lower spring material and has the specific value not inferior to that of German silver and phosphor bronze.
