Aluminium ntawv ci muaj qhov huv, tu cev thiab ci ntsa iab. Nws tuaj yeem ua ke nrog ntau lwm cov ntaub ntawv ntim rau hauv cov khoom ntim khoom sib xyaw, thiab cov nyhuv luam ntawv saum npoo ntawm aluminium ntawv ci zoo dua li lwm cov ntaub ntawv. Ntxiv rau, aluminium foil muaj cov yam ntxwv hauv qab no:
