Aluminium (Al) yog cov khoom siv hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb pob zeb. Ua ke nrog oxygen thiab hydrogen, nws tsim bauxite, uas yog cov feem ntau siv txhuas hauv ore mining. Thawj qhov kev sib cais ntawm aluminium chloride los ntawm hlau aluminium yog nyob rau hauv 1829, tab sis kev lag luam ntau lawm tsis tau pib mus txog rau thaum 1886. Aluminium yog cov nyiaj dawb, tawv, hnyav hlau nrog ib qho kev nqus ntawm 2.7. Nws yog ib tug zoo conductor ntawm hluav taws xob thiab heev corrosion-resistant. Vim yog cov yam ntxwv no, nws tau dhau los ua cov hlau tseem ceeb.Aluminium alloymuaj lub teeb sib txuas lub zog thiab yog li siv nyob rau hauv ntau yam kev lag luam.

 
Kev tsim cov alumina siv 90% ntawm lub ntiaj teb bauxite ntau lawm. Cov seem yog siv hauv kev lag luam xws li abrasives, cov ntaub ntawv refractory, thiab tshuaj. Bauxite kuj tseem siv rau hauv kev tsim cov khoom siv alumina siab, ua cov dej khaws cia lossis ua cov khoom siv hauv cov roj av rau txheej vuam rods thiab fluxes, thiab ua cov flux rau steelmaking thiab ferroalloys.

Kev siv cov txhuas muaj xws li cov khoom siv hluav taws xob, tsheb, nkoj, aircraft tsim, metallurgical thiab tshuaj txheej txheem, kev tsim kho hauv tsev thiab kev lag luam, ntim khoom (cov ntawv txhuas, cov kaus poom), cov khoom siv hauv tsev (tableware, pots).

 
Kev lag luam aluminium tau pib tsim cov thev naus laus zis rau cov khoom siv rov ua dua tshiab nrog cov ntsiab lus txhuas thiab tsim nws tus kheej lub chaw sau. Ib qho kev txhawb siab tseem ceeb rau kev lag luam no ib txwm yog kev txo qis hauv kev siv hluav taws xob, ua ib tuj ntawm txhuas ntau tshaj li ib tuj ntawm thawj txhuas. Qhov no suav nrog nthuav tawm 95% txhuas kua los ntawm bauxite kom txuag tau lub zog. Txhua tuj ntawm recycled txhuas kuj txhais tau tias txuag xya tons ntawm bauxite. Hauv tebchaws Australia, 10% ntawm cov khoom siv txhuas yog los ntawm cov khoom siv rov ua dua tshiab.
