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.

含鋅在36～42%之間的黃銅合金由和固溶體組成﹐其中zui常用的是含鋅40%的六四黃銅。為了改善普通黃銅的性能﹐常添加其他元素﹐如鋁﹑鎳﹑錳﹑錫﹑硅﹑鉛等。鋁能提高黃銅的強度﹑硬度和耐蝕性﹐但使塑性降低﹐適合作海輪冷凝管及其他耐蝕零件。錫能提高黃銅的強度和對海水的耐腐性﹐故稱海軍黃銅﹐用作船舶熱工設(shè)備和螺旋槳等。鉛能改善黃銅的切削性能；這種易切削黃銅常用作鐘表零件。黃銅鑄件常用來制作閥門和管道配件等。船舶常用的消防栓防爆月牙扳手，就是黃銅加鋁鑄造而成。

以錫為主要合金元素的青銅。含錫量一般在3～14%之間，主要用于制作彈性元件和耐磨零件。變形錫青銅的含錫量不超過 8%，有時還添加磷、鉛、鋅等元素。磷是良好的脫氧劑，還能改善流動性和耐磨性。錫青銅中加鉛可改善可切削性和耐磨性，加鋅可改善鑄造性能。這種合金具有較高的力學(xué)性能、減磨性能和耐蝕性，易切削加工，釬焊和焊接性能好，收縮系數(shù)小，無磁性?？捎镁€材火焰噴涂和電弧噴涂制備青銅襯套、軸套、抗磁元件等涂層。尺寸規(guī)格有Ф1.6mm、Ф2.3mm。具有較高的強度、耐蝕性和優(yōu)良的鑄造性能，長期以來廣泛應(yīng)用于各工業(yè)部門中。

(1)錫青銅以錫為主要合金元素的銅基合金稱錫青銅。工業(yè)中使用的錫青銅，錫含量大多在3%～14%之間。錫含量小于5%錫青銅適于冷加工使用;錫含量為5%～7%的錫青銅適于熱加工;錫含量大于10%的錫青銅適于鑄造。
