Koporo e Tšoeu e rarahaneng
Iron Copper Nickel: Limaraka ke T70380, T71050, T70590, T71510. Palo ea tšepe e kentsoeng ka koporo e tšoeu ha ea lokela ho feta 2% ho thibela kutu le ho phatloha.
Manganese Copper Nickel:Limaraka ke T71620, T71660. Koporo e tšoeu ea manganese e na le mocheso o tlase oa ho hanyetsa, o ka sebelisoa maemong a mangata a mocheso, o na le khanyetso e ntle ea kutu, 'me o sebetsa hantle.
Zinc Copper Nickel: Zinc e tšoeu ea koporo e na le lisebelisoa tse phethahetseng tsa mochini, e thibela kutu e matla, serame se setle le sebopeho se chesang sa ho sebetsa, ho seha habonolo, 'me e ka etsoa lithapo, mekoallo le lipoleiti. E sebelisoa ho etsa likarolo tse nepahetseng masimong a lisebelisoa. , limithara, lisebelisoa tsa bongaka, litlhoko tsa letsatsi le letsatsi le likhokahano.
Aluminium Copper Nickel: Ke motsoako o entsoeng ka ho eketsa aluminium ho motsoako oa koporo-nickel o nang le boima ba 8.54. Ts'ebetso ea motsoako e amana le karo-karolelano ea nickel le aluminium ka alloy. Ha Ni:Al=10:1, alloy e na le ts'ebetso e ntle ka ho fetisisa. Aluminium cupronickel e sebelisoang ka tloaelo ke Cu6Ni1.5Al, Cul3Ni3Al, joalo-joalo, e sebelisoang haholo-holo bakeng sa likarolo tse fapaneng tsa matla a phahameng tse thibelang ho bola ha ho etsoa likepe, matla a motlakase, indasteri ea lik'hemik'hale le likarolo tse ling tsa indasteri.
