C2600-1/4H C2100-H弹片用铜合金带
4.热穿透率高:除拉导温性能,模具材料的热穿透率对塑料制品的影响也相当重要,在使用铍青铜的模具上,可以消除过热痕迹,如果热穿透率低,模具壁远端区域的接触温度就会越高,这样会使模具的温差加大,在极端的情况下会引起区域温度的变化从塑料制品的一端的缩痕延伸到另一端的过热的产品痕迹。5.优异的表面质量:铍铜是非常适于表面精加工的,可以直接进行电镀处理,而且粘着性能非常好,铍铜的抛光处理也很容易。
黄铜以锌作主要添加元素的铜合金﹐具有美观的黄色﹐统称黄铜。铜锌二元合金称普通黄铜或称简单黄铜。三元以上的黄铜称特殊黄铜或称复杂黄铜。含锌低於36%的黄铜合金由固溶体组成﹐具有良好的冷加工性能﹐如含锌30%的黄铜常用来制作 壳﹐俗称 壳黄铜或七三黄铜。含锌在36~42%之间的黄铜合金由和固溶体组成﹐其中zui常用的是含锌40%的六四黄铜。为了改善普通黄铜的性能﹐常添加其他元素﹐如铝﹑镍﹑锰﹑锡﹑硅﹑铅等。铝能提高黄铜的强度﹑硬度和耐蚀性﹐但使塑性降低﹐适合作海轮冷凝管及其他耐蚀零件。锡能提高黄铜的强度和对海水的耐腐性﹐故称海军黄铜﹐用作船舶热工设备和螺旋桨等。铅能改善黄铜的切削性能;这种易切削黄铜常用作钟表零件。黄铜铸件常用来制作阀门和管道配件等。船舶常用的消防栓防爆月牙扳手,就是黄铜加铝铸造而成。
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.
