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.

纯铜是玫瑰红色金属，表面形成氧化铜膜后呈紫色，故工业纯铜常称紫铜或电解铜。密度为8-9g/cm2，熔点1083°C。纯铜导电性很好，大量用于制造电线、电缆、电刷等；导热性好，常用来制造须防磁性干扰的磁学仪器、仪表，如罗盘、航空仪表等；塑性很好，易于热压和冷压力加工，可制成管、棒、线、条、带、板、箔等铜材。纯铜产品有冶炼品及加工品两种。 

概述

含铝量一般不超过11.5%，有时还加入适量的铁、镍、锰等元素，以进一步改善性能。铝青铜可热处理强化，其强度比锡青铜高，抗高温氧化性也较好。
