Zusammenfassung:A high-strength copper-nickel-tin alloy consisting of (in weight %): 2.0-10.0% Ni, 2.0-10.0% Sn, 0.01-0.8% Mg, 0.01-1.5% Si, 0.002-0.45% B, 0.004-0.3% P, selectively up to a maximum of 2.0% Co, optionally also up to a maximum 2.5% Zn, selectively up to a maximum of 0.25% Pb, the residue being copper and unavoidable impurities, where 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. The high-strength copper-nickel-tin alloy has Si-containing and B-containing phases and phases of the systems Ni-Si-B, Ni-B, Ni-P, Mg-P, Ni-Si, Mg-Si and other Mg-containing phases which significantly improve the processing properties and use properties of the alloy.
