Thawj qhov sib txawv ntawm 6061 thiab 7075 tuaj yeem pom tam sim ntawd tsuas yog los ntawm saib lawv cov lej ntawm Alloy Qib, thiab 7075 yog nyob rau hauv 7xxx series. Paub txog qhov no, tsis tas khawb mus rau hauv lawv cov ntaub ntawv cov ntaub ntawv cov ntaub ntawv, nws tuaj yeem raug txiav tawm ntawm 6061 yuav muaj ntau dua ntawm silicon thiab 7075 yuav muaj ntau dua ntawm zinc. Thaum soj ntsuam ntawm lub sijhawm muaj tseeb ntawm ob tus kheej alloys, nws kuj tseem tuaj yeem muaj ntau tus lej tseem muaj cov tooj liab ntau dua hauv nws cov tshuaj pleev.
Cov Khoom Siv Neeg Kho Tshuab
Ob qho tib si 6061 thiab 7075 yog cua sov - nrhiav tsis tau, yog li lawv cov tshuab kho tau tsis muaj piv txwv tias yog ib hom kev kho cua sov. Thaum saib ob almoys nyob rau hauv - T6 mob (lub ntsiab lus yog kub}} Ua ntej, lub zog tensile ntawm 7075-t6 yog ze li ntawm 60 xyoo. Lub zog shear ntawm 7075-T6 yog kwv yees li 1.5 zaug ntawm 6061-t6. Tus qub yog nyuaj heev thiab.
Fabrication Xav
6061 Yuav luag txhua tus muaj ntug ntau tshaj 7075 thaum nws los ua kom pom ob qho tib co aluminium hom. Qhov no feem ntau yog vim 6061 muaj qhov hnyav dua thiab lub zog. Qhov qis dua hardness tso cai rau nws yuav tsum tau machined yooj yim dua 7075. Thaum ob qho tib si cov khoom siv tau yooj yim dua 7075 yog feem ntau suav tias tsis yog weldable. Txawm hais tias 6061 tau pom tias yog weldable, kev saib xyuas yuav tsum raug coj los xaiv kom xaiv Weld Folding Hlau. Post - Weld Kho Kom Sov thiab Kev Laus Yuav kom tau txais thaj chaw Weld rov qab mus rau qhov tseem ceeb heev rau kev tawg tom qab vuam.
Cov Ntawv Thov
Muaj ntau daim ntawv thov sib tshooj ntawm 6061 thiab 7075 aluminium alloys. Raws li tau hais dhau los, ob qho tib si yog cov qhab nia cov txheej txheem ntawm txhuas. Ob qho tib si siv rau qhov chaw tsheb kauj vab, cov khoom siv tsim kho vaj tsev, thiab tsim kev tsim kho. Txawm li cas los xij, lawv txawv nyob rau hauv yuav ua li cas lawv siv nyob rau hauv cov chaw no. Piv txwv li, hauv Aerospace kev lag luam, 7075 tuaj yeem siv ntau npaum li cov iav lossis pas nrig, thiab 6061 yuav ua rau muaj kev xav tau ntau dua. Nrog rau cov tsheb tuam, qee cov neeg caij tsheb xum lub zog ntau ntxiv ntawm 70. 7075 muaj ntau dua li 70 xyoo, 6061 yog siv ntau dua rau kev tso tsheb hlau luam thiab lwm yam duab nrog sib npaug contouring.
Thaum twg siv 7075 txhuas vs . 6061}} txhuas?
6061 thiab 7075 aluminium yog nrov hauv kev lag luam uas xav tau siab- lub zog, cov khoom siv lub me me. Nkag siab txog cov khoom ntiag tug yog qhov tseem ceeb thaum sib piv 6061 vs. 7075} mus xaiv cov khoom siv tau rau cov ntawv thov tshwj xeeb.
7075 txhuas yog paub rau nws lub zog zoo tshaj piv rau 6061. Nrog ib qho siab dua zinc cov ntsiab lus, nws yog ib qho ntawm cov muaj zog aluminium alloys muaj. Lub zog no los nrog kev ua lag luam - tawm hauv lub zog, 7075 tsis muaj zog siv nyob rau hauv ib lub zog siv nyob rau hauv ib qho kev kub ntxhov ntau dua 6061. Nws tseem siv tau los tsim cov pob zeb -}}}}} paab khoom, cov tsheb kauj vab, thiab qee cov cuab yeej siv pwm. Nws siv yog qhov zoo tshaj plaws uas muaj zog tshaj plaws uas tsim nyog, thiab qee qhov kev hloov pauv tau tuaj yeem raug kev txi.
Ntawm qhov tod tes, 6061 txhuas ntau dua thiab siv dav dua vim nws cov kws kho zoo, thiab cov tshuab hluav taws xob zoo dua thiab tshuab hluav taws xob zoo dua thiab zoo dua. Lub alloy muaj cov magnesium thiab silicon raws li nws cov ntsiab lus loj, uas pab rau nws lub zog nruab nrab thiab muaj peev xwm ntau. Qhov no ua rau 6061 qhov zoo tagnrho rau cov khoom lag luam Automotive, tshuab hluav taws xob, thiab cov rooj sib txoos kho mob. Nws tseem nyiam nyob rau hauv kev tsim kho kev tsim kho rau cov txheej txheem txheej txheem uas xav tau lub zog zoo {{5} {{qhov hnyav piv thiab corrosion zoo heev.
Thaum txiav txim siab 6061 vs 7075, qhov kev txiav txim siab yuav tsum ua raws li cov kev cai tshwj xeeb ntawm daim ntawv thov. Rau cov phiaj xwm xav tau lub zog siab tshaj plaws thiab qhov twg cov khoom siv txo workability tsis yog qhov teeb meem, 7075 txhuas yog qhov kev xaiv zoo dua. Txawm li cas los xij, rau cov ntawv thov uas xav tau zoo corrosion zoo, Weldability, thiab formability, 6061 txhuas feem ntau yuav tsum tau haum ntau.
