摘要： The invention relates to a method for producing components, media- or drinking-water carrying works, in particular fittings, valves, pipes, press connectors, roof or drainage gutters, as well as components for media- or drinking-water carrying works, in particular fittings, valves, pipes, press connectors, roof or drainage gutters. The object to provide a method for producing components for media- or drinking-water carrying works, in particular fittings, valves, pipes, press connectors, roof or drainage gutters, whereby corrosion-resistant components can be produced simply and economically, which components exhibit low migration of metal ions into the medium, for example of lead and nickel ions into drinking water, is achieved in that an ingot or a rod is continuously cast from a copper alloy, wherein the copper alloy has the following alloying components in wt. %: 2%≦Si≦4.5%, 1%≦Zn≦17%, 0.05%≦Mn≦0.6%,unavoidable accompanying elements to a maximum of 0.5% in total, preferably to a maximum of 0.3% in total, the remainder copper and the ingot or the rod for producing the component is subjected at least to one cold and/or hot forming process.
