Raws li lub xyoo pua nees nkaum, aluminium tau dhau los ua cov hlau tseem ceeb hauv cov dav hlau.Lub dav hlau airframe tau ua daim ntawv thov ntau tshaj plaws rau aluminium alloys.Niaj hnub no, zoo li ntau qhov kev lag luam, aerospace siv dav hauv kev tsim khoom txhuas.
Vim li cas thiaj xaiv Aluminium Alloy hauv Aerospace Kev Lag Luam:
Lub teeb nyhav- Kev siv aluminium alloys txo qhov hnyav ntawm lub dav hlau loj.Nrog rau qhov hnyav li ib feem peb sib dua li cov hlau, nws tso cai rau lub dav hlau nqa hnyav dua, lossis ua kom muaj roj ntau dua.
Siab zog- Aluminium lub zog tso cai rau nws los hloov cov hlau hnyav dua yam tsis muaj qhov poob ntawm lub zog cuam tshuam nrog lwm cov hlau, thaum muaj txiaj ntsig los ntawm nws qhov hnyav dua.Tsis tas li ntawd, cov txheej txheem thauj khoom tuaj yeem siv tau zoo ntawm txhuas lub zog los ua kom cov dav hlau tsim tau ntau dua kev ntseeg siab thiab raug nqi.
Corrosion Resistance- Rau lub dav hlau thiab nws cov neeg caij tsheb, kev xeb tuaj yeem ua rau muaj kev phom sij heev.Txhuas yog cov resistant rau corrosion thiab tshuaj ib puag ncig, ua rau nws tshwj xeeb tshaj yog muaj nqis rau aircrafts ua hauj lwm nyob rau hauv heev corrosive maritime ib puag ncig.
Muaj ntau ntau hom aluminium, tab sis qee qhov haum rau kev lag luam aerospace ntau dua li lwm tus.Piv txwv ntawm xws li txhuas muaj xws li:
2024- Lub ntsiab alloying nyob rau hauv 2024 txhuas yog tooj liab.2024 txhuas tuaj yeem siv tau thaum lub zog siab rau qhov hnyav piv yuav tsum tau.Zoo li 6061 alloy, 2024 yog siv nyob rau hauv tis thiab fuselage lug vim yog qhov nro lawv tau txais thaum lub sijhawm ua haujlwm.
5052 ib- Lub zog siab tshaj plaws ntawm cov qib uas tsis yog-kub-kho tau, 5052 txhuas muab kev ua tau zoo tshaj plaws thiab tuaj yeem kos lossis tsim ua ntau yam duab.Tsis tas li ntawd, nws muaj kev tiv thaiv zoo rau cov dej ntsev corrosion nyob rau hauv marine ib puag ncig.
ib 6061- Cov hlau no muaj cov khoom siv zoo thiab yooj yim welded.Nws yog ib qho kev sib xyaw ua ke rau kev siv dav dav thiab, hauv kev siv aerospace, yog siv rau tis thiab fuselage qauv.Nws yog tshwj xeeb tshaj yog muaj nyob rau hauv homebuilt aircraft.
ib 6063- Feem ntau hu ua "architectural alloy," 6063 txhuas paub txog kev muab cov yam ntxwv ua tiav, thiab feem ntau yog cov khoom siv zoo tshaj plaws rau kev siv anodizing.
ib 7050- Kev xaiv saum toj kawg nkaus rau kev siv dav hlau, alloy 7050 qhia ntau dua corrosion kuj thiab kav ntev dua 7075. Vim tias nws khaws nws cov khoom muaj zog hauv qhov dav, 7050 txhuas muaj peev xwm tswj tau cov kev tiv thaiv kev puas tsuaj thiab corrosion.
ib 7068- 7068 aluminium alloy yog hom muaj zog tshaj plaws ntawm cov hlau tam sim no muaj nyob rau hauv kev lag luam lag luam.Lub teeb yuag nrog kev tiv thaiv corrosion zoo heev, 7068 yog ib qho nyuaj tshaj plaws alloys tam sim no siv tau.
ib 7075- Zinc yog lub ntsiab alloying hauv 7075 txhuas.Nws lub zog zoo ib yam li ntau hom hlau, thiab nws muaj kev ua haujlwm zoo thiab qaug zog zog.Nws yog thawj zaug siv nyob rau hauv Mitsubishi A6M Zero fighter dav hlau thaum Ntiaj Teb Tsov Rog II, thiab tseem siv nyob rau hauv aviation niaj hnub no.
