HMn62-3-3-7锰黄铜

标准：（GB/T 5231-2001）

特性及适用范围：

具有高的强度，耐蚀性是所有黄铜中好的，腐蚀破裂倾向不大，冷态下塑性低，热态下压力加工性好。 化学成分：Cu:60.0-63.0Ni:0.5Al:2.4-3.4Fe:0.10Pb:0.05Mn:2.7-3.7Zn:余量杂质：1.2 HMn62-3-3-7锰黄铜有优异的物理化学性能，纯铜导电性、导热性极佳，许多铜合金的导电、导热性也很好；铜及铜合金对大气和水的抗腐蚀能力也很高；铜是抗磁性物质。有良好的加工性能。铜及某些铜合金塑性很好，容易冷、热成型；铸造铜合金有很好的铸造性能，有某些特殊的机械性能。例如优良的减摩性和耐磨性（如青铜及部分黄铜）；高的弹性极限及疲劳极限（铍青铜等）。色泽美观。由于有以上优良性能，铜及铜合金在电气工业、仪表工业、造船工业及机械制造工业部门中获得了广泛的应用。但铜的储藏量较小，价格较贵，属于应节约使用的材料之一，只有在特殊需要的情况下，例如要求有特殊的磁性、耐蚀性、加工性能、机械性能以及特殊的外观等条件下，才考虑使用。PARent;">ABSolute;top:0;border:0;width:undefinedpx;height:undefinedpx;" sandbox="allow-forms allow-pointer-lock 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%3A32768%2C9%3A32776%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1081344%2C32%3A32%2C40%3A32&guci=2.2.0.0.2.2.0.0&format=0x0&url=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&ea=0&flash=29.0.0&pra=5&wgl=1&dt=1594282478871&bpp=10&bdt=152&idt=190&shv=r20200624&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Dae72f60ec81ac691%3AT%3D1594278309%3AS%3DALNI_Ma1VyONuDNVahmhTYoSN6Guvor0TA&nras=1&correlator=5908497745078&frm=23&ife=1&pv=1&ga_vid=1735009529.1594282479&ga_sid=1594282479&ga_hid=1242621633&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=11&u_java=0&u_h=768&u_w=1360&u_ah=728&u_aw=1360&u_cd=24&u_nplug=14&u_nmime=31&adx=-12245933&ady=-12245933&biw=1343&bih=605&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21066428&oid=3&pvsid=1104219677736997&pem=564&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1360%2C0%2C1360%2C728%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8220&bc=31&ifi=0&uci=0.x1qwko2amlmv&fsb=1&dtd=271" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.x1qwko2amlmv" data-load-complete="true">
