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.

锡青铜在造船、化工、机械、仪表等工业中广泛应用,主要用以制造轴承、轴套等耐磨零件和弹簧等弹性元件以及抗蚀、抗磁零件等。
铍青铜以铍作为主要合金组元的一种无锡青铜。含有1.7~2.5%铍及少 量镍、铬、钛等元素,经过淬火时效处理后,强度 极限可达1250~1500MPa,接近中等强度钢的水 平。在淬火状态下塑性很好,可以加工成各种半成 品。铍青铜具有很高的硬度、弹性极限、疲劳极限 和耐磨性,还具有良好的耐蚀性、导热性和导电 性,受冲击时不产生火花,广泛用作重要的弹性元 件、耐磨零件和防爆工具等。
铍青铜具有良好的综合性能。其力学性能,即强度、硬度、耐磨性和耐疲劳性居铜合金之首。其导电、导热、无磁、抗火花等性能其他铜材无法与之相比。在固溶软态下铍青铜的强度与导电性均处于zui低值,加工硬化以后,强度有所提高,但电导率仍是zui低值。经时效热处理后,其强度及电导率明显上升。
白铜
以镍为主要添加元素的铜合金。铜镍二元合金称普通白铜﹔加有锰﹑铁﹑锌﹑铝等元素的白铜合金称复杂白铜。工业用白铜分为结构白铜和电工白铜两大类。结构白铜的特点是机械性能和耐蚀性好﹐色泽美观。这种白铜广泛用於制造精密机械﹑眼镜配件、化工机械和船舶构件。电工白铜一般有良好的热电性能。锰铜﹑康铜﹑考铜是含锰量不同的锰白铜﹐是制造精密电工仪器﹑变阻器﹑精密电阻﹑应变片﹑热电偶等用的材料。
黄铜
黄铜是由铜和锌所组成的合金。如果只是由铜、锌组成的黄铜就叫作普通黄铜。黄铜常被用于制造阀门、水管、空调内外机连接管和散热器等。
