E 'ngoe ea li-alloys tse matla ka ho fetisisa tsa koporo tse fumanehang' marakeng kajeno ke koporo ea beryllium, e tsejoang hape e le koporo ea selemo kapa boronse ea beryllium. Likarolo tsa khoebo tsa koporo ea beryllium li na le 0.4 ho 2.0 lekholong beryllium. Karo-karolelano e nyenyane ea beryllium ho koporo e etsa lelapa la li-alloys tse phahameng tsa koporo tse nang le matla a holimo joaloka tšepe ea alloy. Lelapa la pele la malapa a mabeli, C17200 le C17300, le kenyelletsa matla a phahameng ka conductivity e itekanetseng, ha lelapa la bobeli, C17500 le C17510, le fana ka conductivity e phahameng ka matla a itekanetseng. Litšobotsi tsa mantlha tsa li-alloys tsena ke karabelo ea tsona e ntle ho liphekolo tse thatafatsang pula, conductivity e ntle ea mocheso, le ho hanyetsa khatello ea maikutlo.
