Abstract: 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.

Abstract: The invention relates to a high-strength as-cast copper alloy containing tin, with excellent hot-workability and cold-workability properties, high resistance to abrasive wear, adhesive wear and fretting wear, and improved corrosion resistance and stress relaxation resistance, consisting (in wt. %) of: 4.0 to 23.0% Sn, 0.05 to 2.0% Si, 0.005 to 0.6 B, 0.001 to 0.08% P, optionally up to a maximum of 2.0% Zn, optionally up to a maximum of 0.6% Fe, optionally up to a maximum of 0.5% Mg, optionally up to a maximum of 0.25% Pb, with the remainder being copper and inevitable impurities, characterised in that the ratio of Si/B of the element content of the elements silicon and boron lies between 0.3 and 10. The invention also relates to a casting variant and a further-processed variant of the tin-containing copper alloy, a production method, and the use of the alloy.
