Qee qhov kev paub txog aluminium alloy
Jun 28, 2023
Aluminium alloy yog ib hom hlau alloy uas yog tsim los ntawm kev sib txuas ntawm txhuas nrog lwm cov hlau lossis cov khoom. Nws yog cov khoom siv nrov rau ntau yam kev siv, suav nrog aerospace, tsheb, kev tsim kho, thiab hluav taws xob. Cov txheej txheem alloying tuaj yeem hloov cov khoom ntawm cov ntshiab txhuas, ua rau nws muaj zog, ruaj khov dua, thiab tiv taus corrosion.
Feem ntau cov alloying ntsiab siv nyob rau hauv aluminium alloys muaj xws li magnesium, tooj liab, zinc, thiab silicon. Kev sib txawv ntawm cov hlau sib txawv ua rau cov khoom sib txawv, xws li lub zog-rau-hnyav piv, zoo machinability, lossis zoo heev corrosion kuj.
Aluminium alloy muaj ntau yam zoo dua lwm yam hlau. Nws yog lub teeb yuag, uas ua rau nws zoo tagnrho rau siv hauv cov ntawv thov qhov hnyav yog qhov kev txhawj xeeb, xws li dav hlau thiab tsheb. Nws kuj tseem ruaj khov thiab tuaj yeem tiv taus ib puag ncig hnyav, uas ua rau nws muaj txiaj ntsig zoo hauv kev tsim kho thiab kev siv dej hiav txwv. Tsis tas li ntawd, aluminium alloy yog ib qho yooj yim mus ua hauj lwm nrog thiab tuaj yeem molded los yog machined rau hauv ntau yam duab thiab ntau thiab tsawg.
Txawm li cas los xij, muaj qee qhov tsis zoo rau kev siv aluminium alloy thiab. Nws tuaj yeem kim dua li lwm cov ntaub ntawv, thiab nws yooj yim rau thermal expansion thiab contraction, ua rau nws tsis haum rau cov ntawv siv kub. Tsis tas li ntawd, qee qhov aluminium alloys tsis muaj zog li lwm yam hlau, uas yuav txwv tsis pub lawv siv hauv qee yam kev siv.
Muaj ntau ntau hom aluminium alloy, tab sis qee qhov feem ntau siv suav nrog:
1. 1000 series - aluminium ntshiab heev uas tsis muaj cov ntsiab lus tseem ceeb alloying, siv tsuas yog rau cov ntawv siv txhuas ntshiab xws li cov tais diav ua noj thiab cov khoom siv hluav taws xob.
2. 2000 series - alloyed nrog tooj liab, siv rau cov qauv siv xws li cov khoom siv dav hlau.
3. 3000 series - alloyed nrog manganese, siv rau kev siv dav dav xws li vov tsev thiab sab.
4. 4000 series - alloyed nrog silicon, siv rau vuam daim ntaub ntawv.
5. 5000 series - alloyed nrog magnesium, siv rau cov qauv siv xws li cov nkoj thiab cov khoom vaj tsev.
6. 6000 series - alloyed nrog magnesium thiab silicon, siv rau cov qauv siv xws li cov khoom siv tsheb thiab cov khoom siv hauv tsev.
7. 7000 series - alloyed nrog zinc, siv rau high-strength structural daim ntaub ntawv xws li aircraft qhov chaw.
8. 8000 series-Lub 8000 series ntawm txhuas alloys tsis yog ib qho tshwj xeeb alloys tab sis yog ib pawg ntawm cov alloys uas muaj cov feem pua ntawm txhuas, nrog rau lwm yam xws li tooj liab, zinc, magnesium, thiab manganese. Qhov tshwj xeeb alloy muaj pes tsawg leeg nyob rau hauv cov koob no tuaj yeem sib txawv nyob ntawm qhov kev npaj siv, nrog rau qee cov alloys xws li 8011, 8079, thiab 8111. Txhua yam ntawm cov hlau no muaj cov khoom sib txawv me ntsis thiab cov yam ntxwv, tab sis txhua tus paub txog lawv lub zog siab-rau-hnyav. ratios thiab zoo heev corrosion kuj.
Qhov sib txawv tseem ceeb ntawm cov hom aluminium alloy no yog lawv cov tshuaj muaj pes tsawg leeg thiab cov khoom. Cov ntsiab lus sib txawv ntawm cov alloying tuaj yeem cuam tshuam lub zog, ductility, thiab corrosion kuj ntawm aluminium, ua rau qee yam alloys zoo dua rau kev siv tshwj xeeb.
Zuag qhia tag nrho, aluminium alloy yog ntau yam khoom siv uas muaj ntau yam zoo rau ntau yam kev siv. Nrog nws cov khoom tshwj xeeb thiab muaj peev xwm tiv taus cov xwm txheej hnyav, nws tseem yog qhov kev xaiv nrov rau ntau lub lag luam.
Shanghai Mengjiang muaj ntau tshaj 16 xyoo kev paub hauv kev tsim aluminium foils. Txais tos tiv tauj peb kom tau txais lub Hoobkas nqi nrog qhov zoo tshaj plaws.
