　　此合金具有以下特性：

　　主要特征：可沉淀硬化的合金，高温（ZUI高815°C）伸张特性ji佳。

　　用途举例：船舶、用柴油机的排气阀主要采用Nimonic 80A锻制而成. Nimonic 80A具有很高的耐热性能,在高温下强度高,变形抗力大,增加了锻造成形的难度.适合于制造螺栓，燃烧室的排气阀。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" src="https://googleads.g.doubleclick.net/pagead/ads?client=ca-pub-6745515041074118&ouTPUt=html&adk=1812271804&adf=3279755396&plat=1%3A1081352%2C2%3A1081352%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=0&pra=5&wgl=1&dt=1618471718735&bpp=26&bdt=M&idt=89&shv=r20210413&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Df43b826f12745ccd-2268431f63c700b7%3AT%3D1618380579%3ART%3D1618380579%3AS%3DALNI_MamEblcYoWowg_oAMi_al7xjlPzyQ&nras=1&correlator=149986564128&frm=23&ife=1&pv=2&ga_vid=1845473087.1618471719&ga_sid=1618471719&ga_hid=1642775356&ga_fc=0&nhd=1&u_tz=480&u_his=47&u_java=0&u_h=1080&u_w=1920&u_ah=1040&u_aw=1920&u_cd=24&u_nplug=0&u_nmime=0&adx=-12245933&ady=-12245933&biw=1209&bih=901&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44740079&oid=3&pvsid=492137362276757&pem=127&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fact%3D1&eae=2&fc=1920&brdim=703%2C0%2C703%2C0%2C1920%2C0%2C1221%2C1045%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=4&bc=31&ifi=1&uci=1.r1lcm97ciwt1&fsb=1&dtd=255" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.r1lcm97ciwt1" data-load-complete="true" frameborder="0">
