Aluminium yog lub teeb hlau nrog cov ntom ntom (2.79 / cm3) thiab muaj zog zoo thiab yas. Aluminium alloy muaj lub zog zoo, lub zog ntawm super-nyuaj aluminium alloy tuaj yeem ncav cuag 600Mpa, thiab lub zog tensile ntawm dog dig hard aluminium alloy kuj tseem 200-450Mpa, uas yog ntau dua li cov hlau, yog li nws yog siv dav hauv kev tsim khoom siv tshuab. Aluminium yog thib ob tsuas yog tau nyiaj thiab tooj liab thiab yog siv rau hauv kev tsim khoom ntawm ntau cov conductors. Aluminium muaj cov thermal conductivity zoo thiab tuaj yeem siv ua cov khoom cua sov. Aluminium kuj muaj kev tiv thaiv zoo corrosion thiab plasticity zoo, thiab tsim nyog rau ntau yam kev ua siab.
Txhuas alloys tau muab faib ua ob pawg: ib qho yog nrum aluminium alloy, thiab muaj aluminium silicon, txhuas tooj, aluminium magnesium, aluminium zinc alloy.The thib ob yog deformed aluminium alloy, uas tau muab faib ua ob pawg: kho kub thiab tsis muaj zog aluminium alloy, aluminium-manganese-based, aluminium-magnesium-based alloy; tshav kub-kho thiab ua kom muaj zog aluminium alloy, aluminium-magnesium-silicon-based, aluminium-tooj liab-magnesium-raws li, txhuas-tooj liab-magnesium zinc thiab hais txog.
