Qsn4-4-2.5锡青铜成分标准Qsn4-4-2.5生产分析介绍

 Qsn4-4-2.5锡青铜

牌号：QSn4-4-2.5

标准：GB/T 5231-2001

中文名称：锡青铜

特性及用途：QSn4-4-2.5为添有锌、铅合金元素的锡青铜，有高的减磨性和良好的可切削性，易于焊接和钎焊，在大气、淡水中具有良好的耐蚀性，只能在冷态下进行压力加工，因含铅热加工时易引起热脆。用于制作在摩擦条件下工作的轴承、卷边轴套、衬套、圆盘以及衬套的内垫等。欢迎您的来电咨询！周工/TEL：138---1616---6343（微信同号）化学成分：铜(Cu:)余量锡(Sn):3.0～5.0锌(Zn):3.0～5.0铝(Al):≤0.002磷(P):≤0.03铁(Fe):≤0.05铅(Pb):1.5～3.5锑(Sb):≤0.002铋(Bi):≤0.002杂质总和%:≤0.2力学能力：抗拉强度：σb (MPa)：≥290伸长率 δ10 (%)：≥35硬度（HRB）：65~85注 ：棒材的纵向室温拉伸力学性能试样状态：M棒材尺寸范围:直径6-500mm,长度0.5-12m(方棒/六角棒等订做)；板材尺寸范围:厚度0.5-80mm,长1-6米,宽0.5-3m管材尺寸范围:外径6-530mm，壁厚0.1-50mm，长度1-12m；带材尺寸范围：厚度0.01-80mm,宽度20-600mm产品规格范围：锻件、棒材（圆棒/方棒/六角棒）、管材（圆管/方管）、板材、带材、环件、丝材、法兰等可根据客户要求生产产品技术标准：国标GB| 美标ASTM| 德标DIN |日标JIS|国际标准 ISO|欧标 CEN|法标 NF产品应用范围：广泛应用于机械、电子、环保、航天航空、电力、石油化学、船舶、轻轨、高铁、精密轴承等各个行业。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%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=32.0.0*&pra=5&wgl=1&dt=1621061166126&bpp=6&bdt=222&idt=244&shv=r20210511&cbv=%2Fr20190131&ptt=9&saldr=aa&cookie=ID%3D1e1559bd2053d62b-22fd2b5d3ec800d6%3AT%3D1621060127%3ART%3D1621060127%3AS%3DALNI_Ma0qIl4F0lR7kkeVroWxU4dpF37nQ&nras=1&correlator=329730220167&frm=23&ife=1&pv=1&ga_vid=232918560.1621061166&ga_sid=1621061166&ga_hid=316546313&ga_fc=0&nhd=1&u_tz=480&u_his=8&u_java=0&u_h=768&u_w=1360&u_ah=728&u_aw=1360&u_cd=24&u_nplug=15&u_nmime=33&adx=-12245933&ady=-12245933&biw=1295&bih=597&isw=730&ish=360&ifk=2699508910&scr_x=0&scr_y=0&eid=44743203&oid=3&pvsid=4007110940231037&pem=308&ref=https%3A%2F%2Fwww.bizrobot.com%2Fcompany_bloginfo.php%3Fadd_suc%3D1&eae=2&fc=1920&brdim=0%2C0%2C0%2C0%2C1360%2C0%2C1360%2C728%2C730%2C360&vis=1&rsz=%7C%7Cs%7C&abl=NS&fu=32772&bc=31&ifi=1&uci=1.kf5owkf03pz3&fsb=1&dtd=267" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true" data-google-container-id="1.kf5owkf03pz3" data-load-complete="true">
