Abstract
A high-strength, high-conductivity copper alloy comprises, all by weight, from 0.8 to 4.0% of Sn, from more than 0.01 to 0.4% of P, from 0.05 to 1.0% of Ni, from 0.05 to 1.0% of one, two or more elements selected from Al, Hf, Be, Mo, Zn, Te, Pb, Co, Zr, and Nb, and the remainder of Cu and inevitable impurities. The impurities include not more than 0.0020% of oxygen.
