一、黃銅
黃銅是銅與鋅的合金。較簡單的黃銅是銅——鋅二元合金，稱為簡單黃銅或普通黃銅。改變黃銅中鋅的含量可以得到不同機械性能的黃銅。黃銅中鋅的含量越高，其強度也較高，塑性稍低。產業中采用的黃銅含鋅量不超過45%，含鋅量再高將會產生脆性，使合金性能變壞。

二、青銅
青銅是歷史上應用較早的一種合金，原指銅錫合金，因顏色呈青灰色，故稱青銅。為了改善合金的工藝性能和機械性能，大部分青銅內還加進其它合金元素，如鉛、鋅、磷等。由于錫是一種稀缺元素，所以產業上還使用很多不含錫的無錫青銅，它們不僅價格便宜，還具有所需要的特種性能。無錫青銅主要有鋁青銅、鈹青銅、錳青銅、硅青銅等。此外還有成份較為復雜的三元或四元青銅。現在除黃銅和白銅（銅鎳合金）以外的銅合金均稱為青銅。
錫(xi)青(qing)(qing)銅(tong)(tong)有(you)較高(gao)的機械(xie)性(xing)(xing)(xing)(xing)能，較好的耐(nai)蝕(shi)性(xing)(xing)(xing)(xing)、減(jian)摩性(xing)(xing)(xing)(xing)和(he)好的鑄造性(xing)(xing)(xing)(xing)能；對過(guo)熱(re)和(he)氣(qi)體的敏(min)感(gan)性(xing)(xing)(xing)(xing)小，焊(han)接性(xing)(xing)(xing)(xing)能好，無鐵磁(ci)性(xing)(xing)(xing)(xing)，收縮系數(shu)小。錫(xi)青(qing)(qing)銅(tong)(tong)在(zai)大氣(qi)、海水(shui)、淡水(shui)和(he)蒸汽中的抗蝕(shi)性(xing)(xing)(xing)(xing)都比黃(huang)銅(tong)(tong)高(gao)。鋁(lv)青(qing)(qing)銅(tong)(tong)有(you)比錫(xi)青(qing)(qing)銅(tong)(tong)高(gao)的機械(xie)性(xing)(xing)(xing)(xing)能和(he)耐(nai)磨(mo)、耐(nai)蝕(shi)、耐(nai)冷、耐(nai)熱(re)、無鐵磁(ci)性(xing)(xing)(xing)(xing)，有(you)良好的活動性(xing)(xing)(xing)(xing)，無偏析(xi)傾向(xiang)，可(ke)得到致(zhi)密的鑄件。在(zai)鋁(lv)青(qing)(qing)銅(tong)(tong)中加進鐵、鎳和(he)錳等元(yuan)素，可(ke)進一步改(gai)善合金的各種性(xing)(xing)(xing)(xing)能。
