Abstract
Copper alloy, the elements of which have the following mass fractions: 46% to 53.5% copper (Cu); 0% to 1.0% aluminum (Al); 0% to 1.40% lead (Pb); 0% to 0.2% iron (Fe); 0% to 0.4% tin (Sn); 0% to 0.0002% boron (B); 0% to 0.2% arsenic (As); and remainder zinc (Zn). In addition, a use of a corresponding copper alloy for an additive manufacturing process, a sanitary fitting (1) with a corresponding copper alloy, and a method for producing a sanitary fitting (1) from a corresponding copper alloy are proposed.
