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.

青铜原指铜锡合金﹐后除黄铜﹑白铜以外的铜合金均称青铜﹐并常在青铜名字前冠以di1主要添加元素的名。锡青铜的铸造性能﹑减摩性能好和机械性能好﹐适合於制造轴承﹑蜗轮﹑齿轮等。铅青铜是现代发动机和磨床广泛使用的轴承材料。铝青铜强度高﹐耐磨性和耐蚀性好﹐用于铸造高载荷的齿轮﹑轴套﹑船用螺旋桨等。磷青铜的 性很限高﹐导电性好﹐适於制造精密 簧和电接触元件﹐铍青铜还用来制造煤矿﹑油库等使用的无火花工具。铍铜是一种过饱和固溶体铜基合金,是机械性能,物理性能,化学性能及抗蚀性能良好;粉末冶金制作针对钨钢,高碳钢、耐高温超硬合金制作的模具需电蚀时,因普通电很损耗大,速度慢,钨铜是比较理想材料。抗弯强度≥667Mpa。
