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.

按功能
按功能劃分,有導(dǎo)電導(dǎo)熱用銅合金(主要有非合金化銅和微合金化銅)、結(jié)構(gòu)用銅合金(幾乎包括所有銅合金)、耐蝕銅合金(主要有錫黃銅、鋁黃銅、各種不白銅、鋁青銅、鈦青銅等)耐磨銅合金(主要有含鉛、錫、鋁、錳等元素復(fù)雜黃銅、鋁青銅等)、易切削銅合金(銅-鉛、銅-碲、銅-銻等合金)、 性銅合金(主要有銻青銅、鋁青銅、鈹青銅、鈦青銅等)阻尼銅合金(高錳銅合金等)、藝術(shù)銅合金(純銅、簡(jiǎn)單單銅、錫青銅、鋁青銅、白銅等)。顯然,許多銅合金都具有多生功能。
材料形成方法
按材料形成方法劃分為可為鑄造銅合金和變形銅合金。事實(shí)上,許多銅合金既可以用于鑄造,又可以用于變形加工。通常變形銅合金可以用于鑄造,而許多鑄造銅合金卻不能進(jìn)行鍛造、擠壓、深沖和拉拔等變形加工。鑄造銅合金和變形銅合金又可以細(xì)分為鑄造用紫銅、黃銅、青銅和白銅。
