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.

錫青銅在造船、化工、機械、儀表等工業(yè)中廣泛應用，主要用以制造軸承、軸套等耐磨零件和彈簧等彈性元件以及抗蝕、抗磁零件等。

鈹青銅以鈹作為主要合金組元的一種無錫青銅。含有1.7～2.5%鈹及少 量鎳、鉻、鈦等元素，經(jīng)過淬火時效處理后，強度 極限可達1250～1500MPa，接近中等強度鋼的水 平。在淬火狀態(tài)下塑性很好，可以加工成各種半成 品。鈹青銅具有很高的硬度、彈性極限、疲勞極限 和耐磨性，還具有良好的耐蝕性、導熱性和導電 性，受沖擊時不產(chǎn)生火花，廣泛用作重要的彈性元 件、耐磨零件和防爆工具等。
