GB-CuPb20Sn铜合金哪里买

铜合金（copper alloy ）以纯铜为基体加入一种或几种其他元素所构成的合金。纯铜呈紫红色﹐又称紫铜。纯铜密度为8.96﹐熔点为1083℃﹐具有优良的导电性﹑导热性﹑延展性和耐蚀性。主要用于制作发电机﹑母线﹑电缆﹑开关装置﹑变压器等电工器材和热交换器﹑管道﹑太阳能加热装置的平板集热器等导热器材。常用的铜合金分为黄铜﹑青铜﹑白铜3大类。
　　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。含锌低于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％的黄铜常用来制作弹壳﹐俗称弹壳黄铜或七三黄铜。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。
　　青铜原指铜锡合金﹐后除黄铜﹑白铜以外的铜合金均称青铜﹐并常在青铜名字前冠以主要添加元素的名。锡青铜的铸造性能﹑减摩性能好和机械性能好﹐适合于制造轴承﹑蜗轮﹑齿轮等。铅青铜是现代发动机和磨床广泛使用的轴承材料。铝青铜强度高﹐耐磨性和耐蚀性好﹐用于铸造高载荷的齿轮﹑轴套﹑船用螺旋桨等。铍青铜和磷青铜的弹性极限高﹐导电性好﹐适于制造精密弹簧和电接触元件﹐铍青铜还用来制造煤矿﹑油库等使用的无火花工具。
