HAl77-2此铜中铝和其他元素相比，铝能显著的提高黄铜的强度和耐蚀性能。在黄铜中加铝，会使a相区明显的移向铜角。当铝含量高时，会出现硬而脆的的Y相。铝的锌含量高时，强化效果好。在HAl77-2此铜中，铝的表面离子化倾向比锌的大，优先形成致密而坚硬的氧化铝膜，可以防止合金的进一步氧化来提高HAl77-2耐蚀性。

HAl77-2具有耐海水腐蚀，有良好的力学性能，可热挤压，冷加工性能良好。HAl77-2化学成分：铜 Cu ：76.0～79.0锌 Zn：余量铅 Pb：≤0.05磷 P：≤0.02铝 Al：1.8～2.5铁 Fe：≤0.06锑 Sb ：≤0.05砷 As ：0.02～0.06铋 Bi：≤0.002杂质：0.3HAl77-2物理性能：密度：8.6弹性模量：102导热率：208.4HAl77-2的力学性能：抗拉强度：360屈服强度：80硬度：65HAl77-2主要应用于船舶用冷凝器管、内陆热电厂用冷凝器等。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%3A8%2C2%3A8%2C8%3A134217728%2C9%3A134250504%2C10%3A32%2C11%3A32%2C16%3A8388608%2C17%3A32%2C24%3A32%2C25%3A32%2C30%3A1048576%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&adsid=NT&dt=1599271018013&bpp=3&bdt=238&idt=156&shv=r20200831&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Db5fb53e0e30065ba%3AT%3D1583737358%3AS%3DALNI_Ma8ikyoXy9eAXtm0boiU2wMlNQHxw&nras=1&correlator=6738990132037&frm=23&ife=1&pv=1&ga_vid=470646100.1599271018&ga_sid=1599271018&ga_hid=933949840&ga_fc=0&iag=3&icsg=42&nhd=1&dssz=4&mdo=0&mso=0&u_tz=480&u_his=50&u_java=0&u_h=1080&u_w=1920&u_ah=1040&u_aw=1920&u_cd=24&u_nplug=27&u_nmime=50&adx=-12245933&ady=-12245933&biw=986&bih=793&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=21066647&oid=3&pvsid=315027397364631&pem=839&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=786%2C19%2C786%2C19%2C1920%2C0%2C1083%2C970%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.pcug94j0ozkh&fsb=1&dtd=218" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.pcug94j0ozkh" data-load-complete="true">
