Abstract

A copper-nickel-tin alloy with excellent castability, hot workability and cold workability, high resistance to abrasive wear, adhesive wear and fretting wear and improved resistance to corrosion and stress relaxation stability, consisting of (in weight %): 2.0-10.0% Ni, 2.0-10.0% Sn, 0.01-1.0% Fe, 0.01-0.8% Mg, 0.01-2.5% Zn, 0.01-1.5% Si, 0.002-0.45% B, 0.004-0.3% P, selectively up to a maximum of 2.0% Co, selectively up to a maximum of 0.25% Pb, the residue being copper and unavoidable impurities. The ratio Si/B of the element-contents in wt. % of the elements silicon and boron is a minimum 0.4 and a maximum 8 such that the copper-nickel-tin alloy has Si-containing and B-containing phases, phases of the systems Ni—Si—B, Ni—B, Fe—B, Ni—P, Fe—P, Mg—P, Ni—Si, and Mg—Si, and other Fe-containing phases and Mg-containing phases.
