铜是最早投入实用用途的金属之一。统一编号系统 (UNS) 是北美公认的锻铜和铸造铜及铜合金合金命名系统。识别方式是前面带有字母 C 的五位数字。优选的船用合金包括铜镍（其在铜金属中表现出最高的耐腐蚀性和侵蚀性，并且还提供相对较高的强度）和铝青铜（其强度更高），以及超高强度铍铜、抑制铝黄铜、磷青铜、含砷金钟黄铜和镍银。在海水中表现良好的铜合金通常也可用于工业和加工领域。铜铸造合金广泛用于制造管道、电气和机械产品以及轴承和工业阀门和配件。对于此类环境，应考虑使用铜镍、铝青铜、硅青铜、锰青铜以及锡和磷青铜。关键词：铜合金；船用合金；统一编号系统 (UNS)
Copper was among the first metals to be put into utilitarian service. The Unified Numbering System (UNS) is the accepted alloy designation system in North America for wrought and cast coppers and copper alloys. Identification is by five-digit numbers preceded by the letter C. Preferred marine alloys include copper nickels, which exhibit the highest corrosion and erosion resistance among copper metals, and also offer relatively high strengths, and aluminum bronzes, which are stronger still, as well as ultrahigh-strength beryllium copper, inhibited aluminum brass, phosphor bronzes, arsenical admiralty brass, and nickel silvers. Copper alloys that perform well in seawater are also often acceptable for use with industrial and process. Copper casting alloys are widely used in the manufacture of plumbing, electrical, and mechanical products and for bearings and industrial valves and fittings. Copper nickels, aluminum bronzes, silicon bronzes, manganese bronzes, and tin and phosphor bronzes should be considered for such environments.
