C003B Alloy Txhuas

Aluminium (Aluminium) yog cov khoom siv hlau, lub cim lub cim yog Al, uas yog cov nyiaj dawb-dawb lub teeb hlau. Nws muaj kev ua tau zoo. Cov khoom lag luam feem ntau ua rau cov pas nrig, flakes, foils, hmoov, ribbons thiab filaments. Nws tuaj yeem tsim cov oxide zaj duab xis los tiv thaiv hlau corrosion hauv huab cua. Cov hmoov txhuas tuaj yeem kub hnyiab tau thaum cua sov hauv huab cua thiab emit ib dazzling dawb nplaim taws. Nws yog yooj yim soluble nyob rau hauv dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide thiab poov tshuaj hydroxide tov, tab sis hardly soluble nyob rau hauv dej. Tus txheeb ze ntom ntom yog 2.70. Melting point yog 660 ° C. Kub taw tes yog 2327 ° C. Cov ntsiab lus ntawm txhuas nyob rau hauv lub ntiaj teb crust yog thib ob tsuas yog oxygen thiab silicon, qeb thib peb, thiab nws yog cov hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb crust. Txoj kev loj hlob ntawm peb lub lag luam tseem ceeb ntawm kev lag luam aviation, kev tsim kho, thiab tsheb yuav tsum muaj cov yam ntxwv ntawm cov ntaub ntawv kom muaj cov khoom tshwj xeeb ntawm txhuas thiab nws cov alloys, uas txhawb kev tsim khoom thiab kev siv cov hlau tshiab no. Daim ntawv thov yog dav heev.
