A lead-free copper alloy on the base of Cu-Zn-Si and its use. The copper alloy is built on the base of copper, zinc and silicon without toxic additives and consists of: 70 to 83% Cu, 1 to 5% Si and the further matrix-active elements: 0.01 to 2% Sn, 0.01 to 0.3% Fe and/or Co, 0.01 to 0.3% Ni, 0.01 to 0.3% Mn, the remainder Zn and unavoidable impurities. The demands for a health-conscious and ecological compatibility are thus naturally met.
