Cov khoom ntawm aluminium yog dab tsi?

Aluminium yog nyiaj-dawb lub teeb hlau. Nws yog malleable. Cov khoom lag luam feem ntau yog ua los ntawm cov kab, rods, nplooj ntawv, foils, hmoov, ribbons thiab filaments. Hauv huab cua ntub tuaj yeem tsim cov oxide zaj duab xis los tiv thaiv hlau corrosion. Aluminium hmoov kho nrog acid yog rhuab nyob rau hauv cov huab cua thiab kub hnyiab heev nrog ib tug blinding dawb nplaim taws.

Nws yog yooj yim soluble nyob rau hauv dilute sulfuric acid, dilute nitric acid, hydrochloric acid, sodium hydroxide thiab poov tshuaj hydroxide tov, insoluble nyob rau hauv dej, tab sis muaj peev xwm reacts nrog dej kub maj mam tsim aluminium hydroxide, nrog rau cov txheeb ze ntom ntawm 2.70, elastic modulus ntawm 70Gpa, Poisson tus piv ntawm 0.33. Melting point yog 660 degree. Kub taw tes ntawm 2327 degree. Nws yog dav siv rau nws lub teeb, zoo hluav taws xob thiab thermal conductivity, siab reflectance thiab oxidation kuj. Cov txhuas siv los ua cov tais diav txhua hnub feem ntau hu ua "steel" lossis "steel". Lub thermal expansion coefficient ntawm Al ntawm 25 ° C yog 0.0000236mm / degree C los yog 23.6 PPM * k{12}}.
