Ndife fakitale yaukadaulo yokonza aluminiyamu, yomwe imapereka mayankho a aluminiyamu nthawi imodzi: Mphamvu ya aluminiyamu yoyera ndi yochepa, koma powonjezera zinthu zosakaniza, mphamvu yake ndi pulasitiki yake zimatha kukonzedwa bwino, ndipo mitundu yosiyanasiyana ya aluminiyamu, monga aluminiyamu yolimba, aluminiyamu yolimba kwambiri, aluminiyamu yolimba dzimbiri ndi aluminiyamu yopangidwa, imatha kupangidwa. Aluminiyamu ndi mitundu yake ya aluminiyamu ili ndi kukana dzimbiri bwino, makamaka filimu ya oxide pamwamba pake, yomwe siimangolimbana ndi dzimbiri, komanso ili ndi kutchinjiriza kwina. Chifukwa cha mphamvu zake zambiri, kukhuthala kochepa komanso kukana dzimbiri bwino, aluminiyamu ya aluminiyamu imagwiritsidwa ntchito kwambiri popanga magalimoto amlengalenga monga ndege ndi maroketi.
