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.

其中zui常用的是含锌40%的六四黄铜。为了改善普通黄铜的性能﹐常添加其他元素﹐如铝﹑镍﹑锰﹑锡﹑硅﹑铅等。铝能提高黄铜的强度﹑硬度和耐蚀性﹐但使塑性降低﹐适合作海轮冷凝管及其他耐蚀零件。锡能提高黄铜的强度和对海水的耐腐性﹐故称海军黄铜﹐用作船舶热工设备和螺旋桨等。铅能改善黄铜的切削性能；这种易切削黄铜常用作钟表零件。黄铜铸件常用来制作阀门和管道配件等。船舶常用的消防栓防爆月牙扳手，就是黄铜加铝铸造而成。

以锡为主要合金元素的青铜。含锡量一般在3～14%之间，主要用于制作弹性元件和耐磨零件。变形锡青铜的含锡量不超过 8%，有时还添加磷、铅、锌等元素。磷是良好的脱氧剂，还能改善流动性和耐磨性。锡青铜中加铅可改善可切削性和耐磨性，加锌可改善铸造性能。这种合金具有较高的力学性能、减磨性能和耐蚀性，易切削加工，钎焊和焊接性能好，收缩系数小，无磁性。可用线材火焰喷涂和电弧喷涂制备青铜衬套、轴套、抗磁元件等涂层。尺寸规格有Ф1.6mm、Ф2.3mm。具有较高的强度、耐蚀性和优良的铸造性能，长期以来广泛应用于各工业部门中。
