Dab tsi yog aluminoy alloy?
Alloy alloy yog ib qho tshuaj lom neeg muaj cov khoom siv lwm cov ntsiab lus ntxiv rau nws cov peev txheej, feem ntau ua kom muaj zog nce ntxiv. Lwm cov ntsiab lus no suav nrog cov hlau, silicon, tooj liab, magnesium, maginces thiab zinc Alloys tau muab plaub-lej lej, uas thawj tus lej qhia tias yog chav kawm dav dav, lossis series, cim los ntawm nws cov ntsiab lus tseem ceeb.
Ntshiab txhuas
1xxx series
Lub 1xxx series alloys muaj cov txhuas 99 feem pua lossis kev coj dawb huv. Cov koob no tau zoo heev corrosion tsis kam, kev ua haujlwm tau zoo heev, nrog rau kev ua haujlwm siab thiab hluav taws xob conductivity. Qhov no yog vim li cas 1xxx series yog feem ntau siv rau kev sib kis, lossis fais fab rooj, kab. Cov Kev Siv Hluav Taws Xob hauv no yog 1350, rau cov ntawv siv hluav taws xob, thiab 1100, rau cov tais ntim khoom noj.
Tshav ntuj sov alloys
Qee cov alloys tau ntxiv dag zog los ntawm kev daws teeb meem kub-kho thiab tom qab ntawd quenching, lossis txias nrawm. Kev kho tshav kub yuav siv cov khoom siv, sib txuam hlau thiab ua kom sov nws rau ib qho tshwj xeeb. Cov alloy ntsiab, hu ua solute, yog homogeneously faib nrog cov txhuas muab tso rau hauv cov kev daws teeb meem. Cov hlau yog tom qab quenched, lossis sai sai txias, uas khov rau solution atoms hauv qhov chaw. Lub solution atoms thiaj li sib txuas ua ke rau hauv ib qho kev faib tawm kom zoo. Qhov no tshwm sim nyob rau hauv chav sov uas yog hu ua kev laus ntuj lossis nyob rau hauv qhov kev ua haujlwm kub tsis yog hu ua kev laus.
2xxx series
Hauv 2xxx series, tooj liab tau siv raws li lub ntsiab cai ua haujlwm tau yooj yim dhau los ntawm kev daws teeb meem kub. Cov alloys muaj kev sib xyaw ua ke zoo thiab muaj zog, tab sis tsis muaj cov qib ntawm cov atmospheric corrosion tiv taus ntau dua li ntau lwm cov alloys alloys. Yog li ntawd, cov alloys feem ntau yog pleev xim rau lossis clad rau cov kev nthuav dav no. Lawv feem ntau clad nrog lub siab-huv alloy lossis 6xxx series alloy kom muaj kev tiv thaiv corrosion. Alloy 2024 Tej zaum qhov feem ntau tau paub dav hlau ya dav hlau.
6xXX Series
Lub 6 xxx series yog ntau yam, kho kom sov, muaj zog heev, weldable siab lub zog txuas nrog cov kev tiv thaiv corrosion zoo heev. Alloys hauv cov koob no muaj silicon thiab magnesium nyob rau hauv thiaj li yuav ua daim ntawv magnesium nyob hauv lub alloy. Extrusion cov khoom lag luam los ntawm 6 xxx series yog thawj qhov kev xaiv rau cov ntawv sau ua vaj tse thiab cov kev thov tsim qauv. Alloy 6061 yog cov feem ntau dav siv alloy hauv cov koob no thiab feem ntau siv hauv tsheb thiab marine thav ntawv. Ib qho ntxiv, qee rooj plaub lub xov tooj tau tsim los ntawm 6xxx series alloy.
7xxx series
Zinc yog cov thawj coj ua ntej rau cov koob tshuaj no, thiab thaum Magnesium ntxiv rau cov txiaj ntsig me, qhov tshwm sim yog qhov ua kom sov. Lwm cov khoom xws li tooj liab thiab chromium kuj tseem yuav ntxiv rau hauv cov khoom me me. Feem ntau cov alloys feem ntau yog 7050 thiab 7075, uas tau siv dav hauv lub dav hlau kev lag luam.
Tsis muaj cua sov alloys
Tsis muaj cua sov-kho alloys tau ntxiv dag zog los ntawm kev ua haujlwm txias. Cov haujlwm txias txias tshwm sim thaum lub sijhawm dov lossis kev quav ntsej lossis yog qhov ua ntawm "ua haujlwm" cov hlau ua kom nws muaj zog dua. Piv txwv li, thaum dov txhuas mus rau lub gauges gauges, nws tau txais zog dua. Qhov no vim tias txias ua haujlwm ua kev tsis sib haum thiab cov neeg seem hauv tus qauv, uas tom qab ntawd inhibits qhov kev txav ntawm atoms txheeb ze rau ib leeg. Qhov no nce lub zog ntawm cov hlau. Alloy cov ntsiab lus xws li cov hlau nplaum sib xyaw ua ke cov nyhuv no, ua rau muaj zog ntau dua.
3xxx series
Manganese yog qhov tseem ceeb alloying keeb hauv cov koob no, feem ntau nrog cov magnesium me me ntxiv. Txawm li cas los xij, tsuas yog txwv feem pua tsawg ntawm manganese tuaj yeem cuam tshuam nrog txhuas. 3003 yog lub hom phiaj nrov rau lub hom phiaj dav dav vim tias nws muaj lub zog nruab nrab thiab kev ua haujlwm zoo thiab yuav siv rau hauv kev siv hluav taws xob xws li cov tais diav. Alloy 3004 thiab nws cov kev hloov kho yog siv hauv lub cev ntawm txhuas haus canus.
4 xxx series
4XXX series alloys tau sib xyaw nrog silicon, uas tuaj yeem muab ntxiv rau hauv cov khoom melting txaus kom tsawg melting pointing ntawm txhuas, tsis muaj kev tsim brittleness. Vim tias qhov no, 4xxx series tsim kom zoo heev vuam hlau thiab cov nyom alloys uas yuav tsum muaj qhov yuav tsum muaj. Alloy 4043 yog ib qho ntawm feem ntau dav siv cov muab khi ua ke alloys rau vuam 6xxx series alloys rau cov kev siv tsheb thiab cov ntawv thov siv tsheb.
5xxx series
Magnesium yog thawj tus neeg sawv cev ua ntej hauv 5xxx series thiab yog ib qho ntawm cov khoom siv tau zoo thiab dav siv alloy. Alloys hauv cov koob no muaj pes tsawg tus yam ntxwv muaj zog, nrog rau weldability zoo thiab tiv taus corrosion hauv lub nkoj marine. Vim tias qhov no, txhuas allots yog dav siv nyob rau hauv tsev thiab kev tsim kho, chaw tso tsheb hlau luam, cov hlab ntsha thiab cov ntaub ntawv cog lus marine. Piv txwv ntawm cov ntawv thov tso Alloy muaj xws li: 5052 hauv cov khoom siv hluav taws xob muaj xws li: 5083 hauv cov ntawv thov marble
