如果是由二種以上的元素組成的多種合金就稱為特殊黃銅。如由鉛、錫、錳、鎳、鐵、硅組成的銅合金。特殊黃銅又叫特種黃銅，它強(qiáng)度高、硬度大、耐化學(xué)腐蝕性強(qiáng)。還有切削加工的機(jī)械性能也較突出。黃銅有較強(qiáng)的耐磨性能。由黃銅所拉成的無縫銅管，質(zhì)軟、耐磨性能強(qiáng)。黃銅無縫管可用于熱交換器和冷凝器、低溫管路、海底運(yùn)輸管。制造板料、條材、棒材、管材，鑄造零件等。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。

column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor differences.

The column in the middle states the norm and its country of origin.

With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.
