Likarolo tse ka sehloohong tsa alloy ea koporo-nickel e thibelang kutu ea CuNi2 e kenyelletsa koporo , nickel (2%), joalo-joalo Le hoja karolo ea nickel e batla e le nyenyane, e na le tšusumetso e kholo ho thepa le libaka tsa ts'ebeliso ea alloy. E na le khanyetso e ntle ea kutu 'me e ka sebetsa ka mokhoa o tsitsitseng libakeng tse fapaneng tse thata. Matla a phahameng, matla a thata a ka fihla ho feta 220MPa. E loketse ho etsa likarolo tse thibelang ho bola ha ho etsoa likepe, lik'hemik'hale le masimo a mang.

Melemo: 1. e ntle haholo ho hanyetsa ho bola

2. malleability e ntle haholo
