黃銅閥門2017-06-0617:50:03什么是黃銅閥門？黃銅閥門就是黃銅的制作而成的。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。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％的黃銅常用來制作彈殼﹐俗稱彈殼黃銅或七三黃銅。含鋅在36～42％之間的黃銅合金由和固溶體組成﹐其中**常用的是含鋅40％的**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。黃銅鑄件常用來制作閥門和管道配件等。以上就是黃銅閥門的介紹,更多黃銅閥門信息詳見上海有色網(wǎng)。進(jìn)口鈹銅2017-06-0617:50:06進(jìn)口鈹銅,是從外國進(jìn)口鈹銅，主要進(jìn)口國有日本、美國。懷遠(yuǎn)上海滬工銅閥門批發(fā)低溫閥門的應(yīng)用，控制了溫度，防止、泄漏等問題。</p><div
