牌号:QCr0.5

　　标准:GB/T 13808-1992

　　特性及适用范围:

　　QCr0.5铬青铜在常温及高温下（400℃）具有较高的强度及硬度，导电性和导热性好，耐磨性和减摩性也很好，经时效硬化处理后，强度、硬度、导电性和导热性均显著提高；易于焊接和钎焊，在大气和淡水中具有良好的抗蚀性，高温抗氧化性好，能很好地在冷态和热态中承受压力加工；但其缺点是对缺口的敏感性较强，在缺口和尖角处造成应力集中，容易引起机械损伤，故不宜作整流子片。　　应用举例:制作工作温度350℃以下的电焊机电极、电机整流子片以及其他各种在高温下工作的、要求有高的强、硬度、导电性和导性的零件，还可以双金属的形式应用于刹车盘和圆盘。　　化学成份:　　铜 Cu :余量　　镍 Ni:≤0.05　　铁 Fe:≤0.1　　铬 Cr:0.4～1.1　　注:≤0.5(杂质)　　力学性能:　　注 :棒材的纵向室温拉伸力学性能　　试样尺寸:直径18～160　　热处理规范:热加工温度900～950℃;淬火温度950～1000℃水冷;l回火温度400～450℃。 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%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&tt_state=W3siaXNzdWVyT3JpZ2luIjoiaHR0cHM6Ly9hZHNlcnZpY2UuZ29vZ2xlLmNvbSISInN0YXRlIjowfSx7Imlzc3Vlck9yaWdpbiI6Imh0dHBzOi8vYXR0ZXN0YXRpb24uYW5kcm9pZC5jb20iLCJzdGF0ZSI6MH1d&dt=1603960288269&bpp=4&bdt=102&idt=109&shv=r20201026&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Db5fb53e0e30065ba-2252073159c400ab%3AT%3D1603337341%3ART%3D1603337341%3AS%3DALNI_MbsujaweaCMAJsjj7FW0iEeXag7Ug&nras=1&correlator=653701414043&frm=23&ife=1&pv=1&ga_vid=796006897.1603960288&ga_sid=1603960288&ga_hid=153110287&ga_fc=0&iag=3&icsg=138&nhd=1&dssz=5&mdo=0&mso=0&u_tz=480&u_his=33&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=1179&bih=1071&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=42530671&oid=3&pvsid=1311297562827181&pem=839&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1920&brdim=912%2C22%2C912%2C22%2C1920%2C0%2C991%2C994%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=8204&bc=31&ifi=0&uci=0.gs9lok7289jc&fsb=1&dtd=197" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.gs9lok7289jc" data-load-complete="true">
