LM’s comparison list between different

norms from Copper alloys

Please read below on the wished for trade-name in the left hand column, and get it translated into LM-language on the right-hand

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.

概述

含鋁量一般不超過11.5%，有時還加入適量的鐵、鎳、錳等元素，以進一步改善 。鋁青銅可熱處理強化，其強度比錫青銅高，抗高溫氧化性也較好。

有較高的強度 良好的耐磨性 用于強度比較高的螺桿、螺帽、銅套、密封環(huán)等，和耐磨的零部件,zui突出的特點就是其良好的耐磨性。

為含有鐵、錳元素的鋁青銅有高的強度和耐磨性，經(jīng)淬火、回火后可提高硬度，有較好的高溫耐蝕性和抗氧化性在大氣、淡水和海水中抗蝕性很好，可切削性尚可，可焊接不易釬焊，熱態(tài)下壓力加工良好。我國已能量產(chǎn)。

 。鋁青銅具有很高的強度、硬度和耐磨性，常用來制造齒輪坯料、螺紋等零件。鋁青銅具有很好的抗蝕性，因此可用來制造耐腐蝕零件，如螺旋槳、閥門等。
