白銅

以鎳為主要添加元素的銅合金。銅鎳二元合金稱普通白銅﹔加有錳﹑鐵﹑鋅﹑鋁等元素的白銅合金稱復(fù)雜白銅。工業(yè)用白銅分為結(jié)構(gòu)白銅和電工白銅兩大類。結(jié)構(gòu)白銅的特點(diǎn)是機(jī)械性能和耐蝕性好﹐色澤美觀。這種白銅廣泛用於制造精密機(jī)械﹑眼鏡配件、化工機(jī)械和船舶構(gòu)件。電工白銅一般有良好的熱電性能。錳銅﹑康銅﹑考銅是含錳量不同的錳白銅﹐是制造精密電工儀器﹑變阻器﹑精密電阻﹑應(yīng)變片﹑熱電偶等用的材料。

黃銅

黃銅是由銅和鋅所組成的合金。如果只是由銅、鋅組成的黃銅就叫作普通黃銅。黃銅常被用于制造閥門、水管、空調(diào)內(nèi)外機(jī)連接管和散熱器等。

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。
