Abstract (en)
[origin: WO2017148568A1] 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, 0.01 to 1.0 % Al, 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.
