7075 txhuas phaj yog txias-kho forged alloy nrog siab zog thiab hardness, deb superior rau me me hlau. 7075 txhuas phaj yog ib qho ntawm cov khoom lag luam muaj zog tshaj plaws, nrog rau kev xeb zoo tib yam, cov khoom siv kho tshuab zoo thiab cov tshuaj tiv thaiv anodic. Cov nplej zoo ua rau qhov sib sib zog nqus drilling kev ua tau zoo dua, cov cuab yeej hnav tsis kam yog txhim kho, cov xov dov yog qhov sib txawv ntawm qhov hnyav, thiab cov khoom siv hlau ntawm kev xaiv kuj yog siab heev thaum cov kev xav tau ceev me me thiab cov kev xav tau hardness kuj siab. 7075 aluminium anodized yog grey. Yog tias tsis muaj dyeing tom qab nyuaj anodizing, xim tom qab ntshiab yog tawm-dawb. Yog hais tias nws yog dyed, nws yuav yog xim dab tsi nws yog dyed. Piv txwv li, cov kaus poom yog dyed tom qab kev kho oxidation. Cov khoom siv tuaj yeem dyed hauv txhua yam xim uas koj xav tau. Hard anodizing nkaus xwb Txawm li cas los xij, oxide zaj duab xis yog thicker. Vim tias nws yog txhuas oxide, nws yog ib qho nyuaj, yog li nws yog hu ua nyuaj oxidation.
7075 txhuas alloy
Ⅰ-C: 7075 Alloy Aluminium Nqe.
Tus nqi ntawm 7075 alloy aluminium yog siab dua li ntawm lwm cov aluminium alloys, vim tias nws cov ntsiab lus alloying ntau dua, suav nrog zinc, magnesium, tooj liab, kev siv thev naus laus zis yog qhov nyuaj dua, thiab cov txiaj ntsig yuav qis dua lwm cov hlau alloy, yog li. nws tus nqi siab dua lwm cov aluminium alloys, 7075 alloy aluminium yog tsuas yog siv nyob rau hauv high-end aviation (lub dav hlau load-bearing Cheebtsam, tsaws iav), foob pob ua ntxaij, propellers, aerospace, thiab lwm yam.
Ⅱ: Cov txheej txheem ntawm 7075 Alloy Anodized Aluminium.
Ⅱ-A: Cov tshuaj muaj pes tsawg leeg ntawm 7075 Alloy Aluminium.
7 series:Al-Mg-Zn-Cu aluminium magnesium zinc tooj liab alloy
Nta:feem ntau zinc, nrog ib tug me me ntawm magnesium thiab tooj liab ntxiv, teej tug mus rau lub aviation series, yog ib tug txhuas-magnesium-zinc-tooj liab alloy, tshav kub-kho alloy, ib tug super-hard aluminium alloy, nrog zoo hnav tsis kam thiab zoo weldability. , tab sis resistant rau Corrosiveness yog pluag. Ntawm lawv, superhard aluminium alloy yog ze rau hardness ntawm hlau. Lub extrusion ceev yog qeeb dua li ntawm 6 series alloy, thiab vuam kev ua tau zoo.
Scope ntawm kev siv:aviation (aircraft load-bearing Cheebtsam, tsaws iav), rockets, propellers, aerospace.
Hom qeb:7050 yog siv rau - phaj, extrusion, dawb forging thiab tuag forging rau dav hlau yam ntxwv qhov chaw. 7075 yog siv rau hauv kev tsim khoom ntawm cov khoom siv dav hlau, cov khoom siv muaj zog siab nrog lub zog siab thiab muaj zog corrosion kuj, thiab pwm tsim.
Ⅱ-B: Anodized ua ntawm 7075 Alloy Aluminium.
Cov thev naus laus zis no siv 7075 nws tus kheej ua cov anode, cov phaj txhuas ua cov cathode, thiab tsim cov oxide zaj duab xis tom qab tau energized hauv electrolyte. Tam sim no, sulfuric acid anodizing, chromic acid anodizing, oxalic acid anodizing, ceramic anodizing thiab nyuaj anodizing yog dav siv nyob rau hauv cov txheej txheem no. Hauv kev xyaum, txoj kev sulfuric acid, txoj kev chromic acid thiab oxalic acid txoj kev yog dav siv. Cov yeeb yaj kiab tsim los ntawm txoj kev sulfuric acid muaj cov tuab tuab, tsis muaj xim thiab pob tshab, thiab muaj qhov porosity ntawm 10 mus rau 15 feem pua. Txawm li cas los xij, qhov tsis zoo ntawm daim nyias nyias no yog qhov yooj yim cuam tshuam los ntawm ntau yam xws li sulfuric acid concentration, qhov kub thiab txias, qhov ceev tam sim no, lub sijhawm oxidation, thiab lwm yam. Cov yeeb yaj kiab tsim los ntawm cov txheej txheem chromic acid muaj qhov kev ntxhib los mos, qhov porosity qis dua li ntawm txoj kev sulfuric acid, thiab zoo heev corrosion kuj. Txawm li cas los xij, los ntawm kev sim cov txiaj ntsig, kev hnav tsis kam yog tsis zoo. Cheebtsam uas yuav tsum tau siab nyob rau hauv no hais txog yuav tsum tsis txhob siv txoj kev no. txoj kev ua. Cov yeeb yaj kiab tsim los ntawm txoj kev oxalic acid muaj cov tuab ntau dua, feem ntau yog xim dawb lossis daj xim, thiab maj mam dhau los ua tsaus nrog qhov nce ntawm cov yeeb yaj kiab tuab, muaj qhov porosity qis, thiab muaj kev tiv thaiv corrosion zoo thiab hnav tsis kam. Hauv cov ntsiab lus, cov txheej txheem anodizing tuaj yeem txhim kho cov khoom nto ntawm 7075, txhim kho hnav tsis kam, corrosion kuj thiab deg hardness.
