I-conductivity kagesi yethusi ingeyesibili kuphela kuneyesiliva, ifinyelela ku-58.5 MS/m (isigidi Siemens ngemitha) ku-20 degree. Lesi sici sikwenza kube yinketho ekhethwayo ku-high-voltage kanye nezimo eziphakeme{4}}zezimo zamanje. Ngokuphambene, ukuqhutshwa kukagesi kwe-aluminium cishe kungama-37.7 MS/m, okungama-64.5% kuphela wekhopha. Ngaphansi kwendawo efanayo-yesigaba, amandla amanje{10}okuthwala amabhasi e-aluminium cishe aphansi ngo-30% kunalawo amabhasi e-copper. Ukuze kuzuzwe ukuguquguquka okufanayo kukagesi,{13}}indawo yesigaba esiphambanayo yamabhasi e-aluminium idinga ukwenyuswa, okuholela ekwenyukeni kwevolumu nesisindo.
Kodwa-ke, ukuminyana okuphezulu kwethusi (8.96g/cm³) nakho kuletha izithiyo. Ezimeni lapho kudingeka khona idizayini engasindi, amabha e-aluminium (anobukhulu obungu-2.7g/cm³) asengakwazi ukuzuza isisindo esiphelele esingaphansi kwaleso samabha ethusi ngokwandisa{3}}indawo yawo ehlukene. Isibonelo, ekuxhumekeni kwamaphakethe ebhethri ezimoto zamandla amasha, amabha e-aluminium amukelwa kabanzi ngenxa yenzuzo yesisindo, nakuba ukwelashwa kwe-oxidation yangaphezulu kuyadingeka ukuze kuthuthukiswe ukumelana nokugqwala.
