Aluminium, nyiaj-dawb lub teeb hlau. Nws yog malleable. Cov khoom siv feem ntau yog ua los ntawm cov pas nrig, cov ntawv, ntawv ci, hmoov, ribbons thiab filaments. Nyob rau hauv huab cua ntub, ib qho oxide zaj duab xis tuaj yeem tsim los tiv thaiv hlau corrosion. Aluminium hmoov kub hnyiab thaum cua sov hauv huab cua thiab emits ib dazzling dawb nplaim taws. Yooj yim soluble hauv dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide thiab potassium hydroxide daws, tab sis insoluble hauv dej. Tus txheeb ze ntom ntom 2.70. Melting point 660 degree. Kub taw tes 2467 degree.
Cov ntsiab lus ntawm txhuas nyob rau hauv lub ntiaj teb crust yog thib peb tom qab oxygen thiab silicon. Nws yog cov hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Txoj kev loj hlob ntawm peb txoj kev lag luam tseem ceeb ntawm aviation, kev tsim kho, thiab tsheb yuav tsum muaj cov khoom siv nrog cov khoom tshwj xeeb ntawm txhuas thiab nws cov alloys, uas pab txhawb kev tsim khoom thiab kev siv ntawm cov hlau tshiab no. Daim ntawv thov yog dav heev.
