Aluminium Ntawv Nyiaj Ntau Lawm cuam tshuam nrog cov txheej txheem muaj kev lag luam uas tau hloov pauv uas tau hloov cov tshuaj txhuas ua cov kua nplaum, hloov kom haum. Kev tsim khoom pib nrog kev rho tawm ntawm Bauxite ore, uas yog ua kom zoo rau hauv alumina (aluminium oxide) los ntawm cov txheej txheem bayer. Alumina yog ces smelted siv electrolysis nyob rau hauv chav Hall-hérice scen los tsim cov hlau ntshiab txhuas. Qhov no molten aluminium tau muab pov rau hauv cov duab loj uas hu ua kev siv, uas yog tom qab cov nplooj ntawv rho tawm ntawm cov theem kub thiab lub ntsej muag txias.
Thaum lub sij hawm kub dov, cov ingot txhuas yog rhuab rau ib puag ncig 5 {0 degree} 0 degree thiab dhau los ntawm cov tuab neeg hnyav kom txo tau nws cov mm. Cov ntaub ntawv yog ces txias-dov ntawm chav tsev kub kom ua tiav txawm tias thij gauges, feem ntau yog tsawg li 0.004 mm (4 microns). Txhawm rau tiv thaiv cov ntawv nplaum, ob txheej ntawm ntawv ci tau dov ib txhij, nrog sab hauv cov ntawv sib chwv thiab sab hauv sab ntxiv matte. Tus txheej txheem no, hu ua "doubling," ua kom pom cov ntawv ci ua ke thiab hloov tau.
Cov kauj ruam kawg suav nrog kev siv anneal (tshav kub) los txhim kho cov ntawv sau, txiav cov ntawv sau rau hauv qhov xav tau dav, thiab rewinding lawv rau hauv rolls. Cov kev ntsuas siab ua kom muaj kev ntsuas zoo, xws li tuab tuab thiab kev nrhiav kom pom lub cev, xyuas kom meej. Aluminium ntawv ci cov khoom lag luam zoo nkauj-lub teeb, impermability rau cov dej noo thiab roj cua sov - ua kom zoo tshaj plaws rau kev ntim, rwb thaiv tsev, thiab ua noj. Kev ua kom zoo li embossing lossis laminating nrog cov polymers txuas ntxiv nthuav nws cov ntawv thov hauv cov khoom noj khoom haus, thiab khoom siv hluav taws xob.
Kev txiav txim siab ib puag ncig yog kev ua haujlwm rau niaj hnub tsim khoom. Aluminium yog infinittely rov ua dua, xav tau tsuas yog 5% ntawm lub zog siv hauv kev tsim cov khoom lag luam. Ntau cov tuam ntxhab tam sim no ua ntej rov ua cov ntsiab lus thiab cov txheej txheem hluav taws xob txuag kom txo cov kab mob carbon. Txawm hais tias nws nyias nyias, txhuas ntawv ci lub zog thiab cov khoom muaj zog tau ua rau nws lub luag haujlwm tseem ceeb thoob plaws kev lag luam, ntsuas kev ua haujlwm nrog kev ruaj ntseg.
