Aluminium yog cov khoom siv tshuaj. Nws cov cim tshuaj yog Al, thiab nws tus lej atomic yog 13. Cov ntsiab lus ntawm txhuas nyob rau hauv lub ntiaj teb crust yog thib ob tsuas yog oxygen thiab silicon, qeb thib peb. Nws yog cov hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Hauv qeb ntawm cov hlau, nws yog qeb thib ob loj tshaj plaws tom qab hlau. Thaum kawg ntawm lub xyoo pua 19th, txhuas tau tshwm sim los ua ib qho kev sib tw hlau hauv kev siv engineering thiab tau nyob hauv vogue rau ib pliag. Txoj kev loj hlob ntawm peb txoj kev lag luam loj ntawm aviation, kev tsim kho, thiab tsheb yuav tsum muaj cov khoom siv uas muaj cov khoom tshwj xeeb ntawm txhuas thiab nws cov alloys, uas txhawb kev tsim khoom thiab kev siv cov hlau tshiab no. Aluminium yog dav siv.
Aluminium alloy yog ib lo lus dav dav rau txhuas raws li cov alloys. Cov ntsiab lus tseem ceeb ntawm cov hlau muaj xws li tooj liab, silicon, magnesium, zinc, thiab manganese, thaum cov hlau alloy thib ob muaj xws li npib tsib xee, hlau, titanium, chromium, thiab lithium.
Aluminium alloys muaj qhov ntom ntom, tab sis kuj muaj zog, ze rau lossis zoo dua cov hlau zoo. Lawv muaj cov yas zoo thiab tuaj yeem ua rau ntau yam duab. Lawv muaj cov khoom siv hluav taws xob zoo heev, thermal conductivity, thiab corrosion kuj. Lawv tau siv dav hauv kev lag luam, nrog kev siv tsuas yog thib ob rau cov hlau.
