    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a component for carrying medium water or drinking water (especially a joint, valve, pipe, press-coupled part, eaves gutter or drainage gutter), and the component for carrying medium water or drinking water (especially a joint, valve, pipe, press-coupled part, eaves gutter or drainage gutter). SOLUTION: In the method for manufacturing the component for carrying medium water or drinking water, especially the joint, the valve, the pipe, the press-coupled part, the eaves gutter or the drainage gutter, an ingot or a rod is continuously cast from a copper alloy. The copper alloy comprises 2-4.5 wt.% Si, 1-17 wt.% Zn and 0.05-0.6 wt.% Mn as alloy components, up to 0.5 wt.%, preferably up to 0.3 wt.% of unavoidable accompanying elements in total and the balance being copper. In the method, the ingot or the rod for manufacturing the component is at least once subjected to cold- and/or hot-forming. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供一种用于制造用于运送中水或饮用水的部件的方法(特别是接头,阀,管,压配合部,檐沟或排水沟)以及用于承载介质的部件 水或饮用水(特别是接头,阀门,管道,压配件,檐沟或排水沟)。 解决方案:在制造用于运输中水或饮用水的部件,特别是接头,阀门,管道,压配合部件,檐沟或排水沟槽的方法中,锭或杆是 从铜合金连续铸造。 铜合金包含2-4.5重量%的Si,1-17重量%的Zn和0.05-0.6重量%的Mn作为合金组分,最多0.5重量%,优选至多0.3重量%的不可避免的伴随元素 铜和铜的总和。 在该方法中,用于制造部件的锭或棒至少经受冷 - 和/或热成形。 版权所有(C)2007,JPO&INPIT
