Classification thiab Characterization ntawm Aluminium

Aluminium yog ib hom hlau, lub cim cim yog Al, yog ib hom nyiaj dawb lub teeb hlau. Nws yog malleable. Cov khoom lag luam feem ntau yog ua hauv pas nrig, flake, ntawv ci, hmoov, ribbon thiab filamentous daim ntawv. Nyob rau hauv cov huab cua ntub tuaj yeem tsim ib txheej ntawm oxide zaj duab xis los tiv thaiv hlau corrosion. Cov hmoov txhuas hluav taws kub hnyiab nrog cua sov hauv huab cua thiab emits ib lub qhov muag tsis pom nplaim taws. Soluble nyob rau hauv dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide thiab poov tshuaj hydroxide tov, insoluble nyob rau hauv dej. Tus txheeb ze ntom ntom yog 2.70. Melting point 660 degree. Kub taw tes 2327 degree. Aluminium yog cov khoom siv hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb lub pob zeb, qeb thib peb tom qab oxygen thiab silicon. Txoj kev loj hlob ntawm peb lub lag luam tseem ceeb, aviation, kev tsim kho thiab tsheb, yuav tsum muaj cov yam ntxwv ntawm cov khoom siv nrog cov khoom tshwj xeeb ntawm aluminium thiab nws cov alloys, uas muaj txiaj ntsig zoo rau kev tsim khoom thiab kev siv ntawm cov hlau tshiab no. Nws yog dav siv.
