Aluminium, nws yog ib qho tshuaj lom neeg. Nws cov cim tshuaj yog Al, thiab nws tus lej atomic yog 13. Txhuas yog cov hlau ntau tshaj plaws nyob rau hauv lub ntiaj teb lub crust, qeb thib peb tom qab oxygen thiab silicon. Nyob rau hauv cov hlau ntau yam, thib ob tsuas yog steel, rau qhov thib ob loj qeb ntawm hlau. Nws tsis yog txog thaum xyoo 19th lig uas txhuas tau tshwm sim los ua cov hlau sib tw rau kev siv engineering thiab ua txhua yam npau taws. 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 txhuas thiab nws cov alloys, uas pab txhawb kev tsim khoom thiab kev siv ntawm cov hlau tshiab no. Aluminium yog siv rau ntau yam kev siv.
Aluminium ntshiab yog mos, tsis muaj zog thiab malleable. Nws tuaj yeem raug kos rau hauv filaments thiab dov rau hauv foils thiab siv ntau hauv kev tsim cov xov hlau, cables, xov tooj cua kev lag luam, thiab ntim khoom. Nws yog kwv yees li ob feem peb ntawm cov conductive li tooj liab, tab sis vim nws tsuas yog ib feem peb li ntom li tooj liab, nws yog li ob zaug li conductive thiab pheej yig dua tooj liab, piv nrog txhuas hlau ntawm qhov sib npaug thiab ntev.
Cov khoom siv aluminium
Aluminium alloy yog lub ntsiab lus dav dav rau aluminium-raws li alloys. Lub ntsiab alloying ntsiab yog tooj liab, silicon, magnesium, zinc, manganese, me me alloying ntsiab yog npib tsib xee, hlau, titanium, chromium, lithium thiab hais txog.
Aluminium alloy muaj tsawg ntom ntom, tab sis kuj muaj lub zog siab, nrog cov hluav taws xob zoo, nrog cov hluav taws xob zoo, siv tau dav hauv kev lag luam, kev siv ob tsuas yog rau steel.
Kev faib tawm ntawm cov khoom siv aluminium: Rolling thiab casting cov ntaub ntawv Rolling thiab casting cov ntaub ntawv uas tsis yog-kub kho hom alloy ntshiab aluminium alloy (1000 series) aluminium manganese alloy (3000 series) aluminium silicon alloy (4000 series) aluminium magnesium alloy (5000 series) kub kho hom alloy aluminium tooj liab magnesium alloy (2000 series) aluminium magnesium silicon alloy (6000 Aluminium zinc magnesium alloy (7000 series) cov khoom siv tsis yog cua sov kho hom alloy ntshiab aluminium alloy aluminium silicon alloy (ADC1) aluminium magnesium alloy (ADC5, ADC6) Thaum tshav kub kub kho hom alloy aluminium tooj liab silicon alloy (ADC10, ADC12) aluminium-Cu-Mg-silicon alloy (ADC14) aluminium-Mg-silicon alloy (ADC3) Kev faib tawm: cov khoom dov: Sheet, Phaj, Coil, strip extrusion khoom: yeeb nkab, khoom bar Profiles, Castings: castings.
