C2600 R-EH C2600 R-H銅合金切削性能好/耐磨耐腐蝕

鈹青銅具有良好的綜合性能。其力學(xué)性能，即強(qiáng)度、硬度、耐磨性和耐疲勞性居銅合金之首。其導(dǎo)電、導(dǎo)熱、無磁、抗火花等性能其他銅材無法與之相比。在固溶軟態(tài)下鈹青銅的強(qiáng)度與導(dǎo)電性均處于zui低值，加工硬化以后，強(qiáng)度有所提高，但電導(dǎo)率仍是zui低值。經(jīng)時效熱處理后，其強(qiáng)度及電導(dǎo)率明顯上升。

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。
