含銅在62%～68%，塑性強(qiáng)，制造耐壓設(shè)備等。

根據(jù)黃銅中所含合金元素種類的不同，黃銅分為普通黃銅和特殊黃銅兩種。壓力加工用的黃銅稱為變形黃銅。黃銅以鋅作主要添加元素的銅合金﹐具有美觀的黃色﹐統(tǒng)稱黃銅。銅鋅二元合金稱普通黃銅或稱簡(jiǎn)單黃銅。三元以上的黃銅稱特殊黃銅或稱復(fù)雜黃銅。含鋅低於36%的黃銅合金由固溶體組成﹐具有良好的冷加工性能﹐如含鋅30%的黃銅常用來(lái)制作 殼﹐俗稱?

殼黃銅或七三黃銅。含鋅在36～42%之間的黃銅合金由和固溶體組成﹐其中zui常用的是含鋅40%的六四黃銅。為了改善普通黃銅的性能﹐常添加其他元素﹐如鋁﹑鎳﹑錳﹑錫﹑硅﹑鉛等。鋁能提高黃銅的強(qiáng)度﹑硬度和耐蝕性﹐但使塑性降低﹐適合作海輪冷凝管及其他耐蝕零件。錫能提高黃銅的強(qiáng)度和對(duì)海水的耐腐性﹐故稱海軍黃銅﹐用作船舶熱工設(shè)備和螺旋槳等。鉛能改善黃銅的切削性能﹔這種易切削黃銅常用作鐘表零件。黃銅鑄件常用來(lái)制作閥門和管道配件等。

青銅

青銅是我國(guó)使用zui早的合金，至今已有三千多年的歷史。
