The invention relates to a copper-zinc alloy, in particular for providing components for a plumbing fitting. Said alloy comprises (in % by weight): between 63.5 and 63.8 % Cu, between 35.2 and 35.6 % Zn, between 0.17 and 0.20 % Pb, between 0.32 and 0.4 % Al, between 0.11 and 0.13 % As, between 0.16 and 0.2 % Fe, between 0.0 and 0.2 % Sn, between 0.0 and 0.2 % Mn, and residual constituents in respective maximum quantities of 0.02 %. The invention also relates to a method for producing a cast component comprising a copper-zinc alloy of this type. The copper-zinc alloy and the components produced therewith permit a particularly environmentally-friendly, cost-effective production of plumbing fittings. |
