7075-T6 Aluminium yog dab tsi?
7075 txhuas alloy, muab los ntawmGNEE, yog zinc-dominated aluminium alloy feem ntau hu uaaircraft aluminiumlos yogaerospace aluminium. Nws yog thawj qhov siab -lub zogAl-Zn-Mg-Cualloy kom muaj kev sib xyaw ua ke ntawm chromium, txhim kho kev tiv thaiv kev ntxhov siab -corrosion cracking hauv cov khoom siv. Lub alloy feem ntau muaj87.1-91.4% txhuas, nrogzinc ntawm 5-6%, magnesium ntawm 2.1-2.9%, thiabtooj liab ntawm 1.2-2.0%, nrog rau cov tswj me me (tsawg dua lossis sib npaug li 0.5%) ntawm silicon, titanium, chromium, hlau, manganese, thiab lwm yam.
7075-T6 txhuashais txog 7075 alloy nyob rau hauvT6 zog, tiav los ntawm kev kho cua sov, homogenization ntawm cam khwb cia hlau ntawm kwv yees li450 degree,sai quenching, thiab tom qab dag aging nyob ib ncig ntawm120℃rau 24 teev. Qhov kev tswj cua sov no- txoj kev kho mob tso cai rau cov hlau mus txog nwsncov zogthiab txheem mechanical kev ua tau zoo.
Dab tsi ua rau 7075 Aluminium Stand Out?
Ntawm tag nrho cov aluminium alloys, lub7075 series muab lub zog siab tshaj plaws, ncav qib piv rau ntau cov hlau. Thaum lub zog yog nws cov cwj pwm tseem ceeb tshaj plaws, nws yog kev sib xyaw ua ke ntawmTsawg ceev, zoo heev machinability, thiab zoo corrosion kujuas ua rau 7075 tshwj xeeb tshaj yog haum raucov yam ntxwv ntawm cov qauv kev nyuab siab heev.
Txawm hais tias nws qhov kev tiv thaiv corrosion qis dua li ntawm qee cov aluminium alloys, nws tseem ua tau zoo dua li feem ntau2000-series alloys. Hauv kev siv qhov twg aluminium alloy2024yog xav tias,7075feem ntau xaiv hloov thaummechanical zog ntau duayog yuav tsum tau.
