Copper-zinc-alloy comprises (in wt.%): zinc (28-36); silicon (0.5-2.3); manganese (1.5-2.5); nickel (0.2-3); aluminum (0.5-1.5); iron (0.1-1); optionally lead (up to 0.1), tin (up to 0.2), phosphorus (up to 0.1) and sulfur (up to 0.08); and the rest of copper and unavoidable impurities with iron-nickel-manganese-containing silicide mixture stored in the matrix. An independent claim is included for producing pipes or rods made from the copper-zinc-alloy, comprising further processing the alloy by extruding at 600-800[deg] C and cold forming the extruded alloy or cold forming and annealing the extruded alloy at 250-700[deg] C. |
