ABSTRACT:
A copper based alloy consists essentially, by weight %, of 15 to 35% Zn, 7 to 14% Ni, 0.1 to 2% or less Mn, 0.01 to 0.5% Fe, 0.0005 to 0.1% P, at least one or two elements selected from the group consisting of 0.001 to 0.9% Si, 0.0003 to 0.02% Pb, and 0.0003 to 0.01% C, the total content of the selected at least two elements being limited to a range of 0.0006 to 0.9%, and the balance of Cu and inevitable impurities. The copper based alloy has excellent blankability as well as good corrosion resistance and high strength.
