Chemical Composition of Cast Brass
铜合金，尤其是黄铜，是在一个室温的情况下常被用来进行铸造的合金。这种合金因其介于铝和钢两种金属之间的高强度、质量和成本这三方面的折衷而被采用，它含有约60％的铜，其余部分包括矿石、碳、硫、锡和铜精等其他元素。
铜是以铜为主体而配以其他元素制成的合金，这里介绍了铸造黄铜合金的化学成分。黄铜是一种Cu-Zn（......

铜是以铜为主体而配以其他元素制成的合金这里介绍了铸造黄铜合金的化学成分黄铜是一种cuzn铜锌合金它由铜cu和锌zn这两种金属元素混合合成的在一般的黄铜中用铜的重量占整个合金的质量的比例为6090而用锌的重量占整个合金的质量比例为1040
除cuzn铜锌外黄铜合金也可以同其他少量的元素混合以提高它的机械性能和耐腐蚀性其他元素中一般最常用的元素是铝al大约低于13铝能够增强黄铜合金的力学特性使其抗疲劳性更强此外硫也可以添加其用量大约可以达到022左右可以改善合金的可锻性和可切削性其他元素如锰mn锡sn和镍ni也可以添加可增进合金的韧性一般添加剂的最大含量也通常不能超过4否则将会影响其成色性能和机械特性
