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.
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。
