Lub raj ntshiab aluminium yog me me, feem ntau ze rau 2700kg / m3, uas yog kwv yees li 35% ntawm qhov ntom ntawm cov hlau. Cov ntshiab txhuas tau ntau dua ob npaug nws lub zog los ntawm kev ua haujlwm txias, thiab tuaj yeem raug ntxiv los ntawm kev ntxiv cov hlau nplaum, zinc, tooj liab, manganese, silicon, lithium thiab strontium. Cov kev sib ntxiv ntawm lwm cov ntsiab yog ntxiv dag zog los ntawm kev kho cua sov, thiab lub zog tshwj xeeb tuaj yeem piv nrog cov qib high-quality alloy steel. Aluminium yog qhov yooj yim rau txheej txheem: aluminium tuaj yeem nrum los ntawm txhua qhov txheej txheem casting. Lub raj aluminium muaj plasticity zoo thiab tuaj yeem dov mus rau hauv nyias phaj thiab foils; kos rau hauv cov kav dej thiab tub lim; extruded rau hauv ntau cov ntaub ntawv txog pej xeem; thiab ntau lub tshuab ua cuab yeej tuaj yeem ncav cuag qhov siab tshaj plaws yog siv rau kev siv lub tshuab xws li tig, milling, tho txawv thiab phiaj xwm.
Aluminium ntshiab lub raj tau zoo corrosion tsis kam, thiab saum npoo ntawm txhuas thiab nws cov alloy yog yooj yim los ua daim duab tuab thiab ruaj Al2O3 tiv thaiv zaj duab xis. No tiv thaiv zaj duab xis yuav raug rhuav tshem tsuas yog los ntawm qhov kev ua hnyav ntawm halogen ions lossis alkali ions. Yog li ntawd, aluminium muaj qhov zoo tsis kam rau atmospheric corrosion thiab dej corrosion. Nws tiv taus qhov kev xeb ntawm feem ntau cov acids thiab organic, siv cov tshuaj ua kom tsis muaj zog, thiab tiv taus kev ua kom tsis muaj zog corrosion; nws tuaj yeem txhim kho qhov txhim kho corrosion ntawm aluminium alloy los ntawm kev tiv thaiv kev tiv thaiv. Aluminium tsis cuam tshuam rau qhov kub tsawg. Thaum lub txhuas nyob rau hauv qis dua qib degrees Celsius, lub zog thiab plasticity yuav tsis txo nrog qhov txo qis ntawm qhov kub thiab txias, tab sis yuav nce ntxiv.
Aluminium ntshiab lub raj muaj qhov zoo hluav taws xob thiab thermal conductivity thiab muaj zog muaj zog cuam tshuam: qhov chaw polished saum npoo ntawm txhuas muaj qhov cuam tshuam ntau dua 80% rau lub teeb dawb, thiab qhov siab dua purity, qhov cuam tshuam ntau dua. Tib lub sijhawm, aluminium muaj qhov cuam tshuam zoo ntawm infrared, ultraviolet, hluav taws xob tsis, hluav taws xob cua sov, thiab lwm yam.
