HPb62-0.8铅黄铜化学成分力学性能HPb62-0.8抗疲劳的强度

 HPb62-0.8铅黄铜

材料名称：专用铅黄铜线(半硬,3.8～6.0mm)

牌号：HPb62-0.8

标准：GB/T 14956-1994

●特性及适用范围：

可切削性较HPb63-3低,是含铅高的铅黄铜,不能热压力加工，减摩性能好，易纤焊和焊接，对一般腐蚀有良好的稳定性，但有腐蚀破裂倾向。●化学成份：铜Cu ：60.0～63.0锌Zn：余量铅Pb：0.5～1.2磷P：≤0.01铝Al：≤0.2铁Fe：≤0.2锑Sb ：≤0.005铋Bi：≤0.002注：≤0.75(杂质)●力学性能：抗拉强度σb (MPa)：390～540伸长率δ10 (％)：≥15注：线材的室温拉伸力学性能试样尺寸：直径3.8～6.0铅黄铜是极为重要的、应用***为广泛的一种复杂黄铜，它具有优良切削性能、耐磨性能和高强度，主要用于机械工程中各种连接件、阀门、阀杆轴承保持中，其中热锻阀门坯料、制锁业、钟表业是三大重要市场，铅黄铜成本低廉是其广泛应用的重要前提，其合金成分中可以包容多种合金元素，且含量要求比较宽松，又为铜合金原料综合利用奠定了基础。ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" SANdbox="allow-forms allow-popUPS allow-popups-to-escape-sandbox allow-same-origin allow-scripts allow-top-navigation-by-user-activation" frameborder="0" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A32776%2C2%3A32776%2C8%3A134217728%2C9%3A134250504%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=32.0.0*&pra=5&wgl=1&dt=1620805885374&bpp=8&bdt=501&idt=212&shv=r20210510&cbv=%2Fr20190131&ptt=9&saldr=aa&cookie=ID%3D113c8823094a3c32-227bf153f2c700f8%3AT%3D1620630738%3ART%3D1620630738%3AS%3DALNI_MapIGQPEmsnA-xlF1kK2eeUfsUdtA&nras=1&correlator=8098189388818&frm=23&ife=1&pv=2&ga_vid=2121822645.1620805886&ga_sid=1620805886&ga_hid=328423475&ga_fc=0&nhd=1&u_tz=480&u_his=15&u_java=0&u_h=768&u_w=1360&u_ah=728&u_aw=1360&u_cd=24&u_nplug=15&u_nmime=33&adx=-12245933&ady=-12245933&biw=1295&bih=597&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530672%2C31060615%2C31060956&oid=3&pvsid=373419907522480&pem=423&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1360%2C0%2C1360%2C728%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.kwgyase1r8p2&fsb=1&dtd=240" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.kwgyase1r8p2" data-load-complete="true">
