磷是QSn6.5-0.4合金的有效脱氧剂，元素磷的加入，提高QSn6.5-0.4的强度、硬度、弹性高限、弹性模量和疲劳强度，改善耐蚀性能和铸造时的流动性。缺点是加大铸锭的反偏析。

QSn6.5-0.4有高的强度、弹性、耐磨性和抗磁性，在热态和冷态下压力加工性良好，对电火花有较高的抗燃性，可焊接和钎焊，可切削性良好，在大气、淡水中耐蚀。因含磷量较高，其疲劳强度抗性较高，弹性和耐磨性较好，但在热加工时有热脆性，只能接受冷压力加工。QSn6.5-0.4化学成分：铜Cu：余量锡Sn：6.0～7.0铅Pb：≤0.02磷P：0.26-0.4铝Al：≤0.002铁Fe：≤0.02硅Si：≤0.002锑Sb：≤0.002铋Bi：≤0.002杂质：≤0.1QSn6.5-0.4软态物理性能：密度：8.8热导率：87.12硬度：70-90摩擦系数：0.01（有润滑剂）抗拉强度：350-450屈服强度：200-250退火温度：520-620QSn6.5-0.4焊接性能：易于锡焊、铜焊、闪光焊、也能进行电弧焊、电焊，不易进行埋弧焊和电渣焊。QSn6.5-0.4主要用于制作制造弹性原件、耐磨零件及金属网等。在航空工业中主要用于组合空速表、进气压力表等膜片、弹簧片等。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&dt=1599272377448&bpp=5&bdt=63&idt=27&shv=r20200831&cbv=r20190131&ptt=9&saldr=aa&cookie=ID%3Db5fb53e0e30065ba%3AT%3D1583737358%3AS%3DALNI_Ma8ikyoXy9eAXtm0boiU2wMlNQHxw&nras=1&correlator=6319820826867&frm=23&ife=1&pv=2&ga_vid=210193926.1599272378&ga_sid=1599272378&ga_hid=913135125&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=42530622&oid=3&pvsid=4451828927492344&pem=839&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&rx=0&eae=2&fc=1664&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.f5sgv7tah3y9&fsb=1&dtd=76" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="0.f5sgv7tah3y9" data-load-complete="true">
