Copper (Cu) le koporo-nickel (copper-nickel (Cu-Ni) alloys ka bobeli ke lisebelisoa tsa bohlokoa, empa metsoako ea tsona e ikhethang le thepa li etsa hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng Ho utloisisa phapang ena ke senotlolo sa ho khetha thepa e nepahetseng bakeng sa morero oa hau-'me ha ho tluoa tabeng ea maemo a boima, lihlahisoa tsa rona tsa Cu-Ni li hlahella e le khetho e phahameng.
Bohareng ba eona, koporo e hloekileng ke tšepe e bonolo, e bonolo, e tsejoang ka ho sebetsa hantle ha motlakase le mocheso. E na le ductile e phahameng haholo, e etsang hore ho be bonolo ho bōptjoa hore e be lithapo, liphaephe le maqephe, e leng se hlalosang tšebeliso e pharaletseng ea lithapo tsa motlakase le lisebelisoa tsa mocheso. Leha ho le joalo, koporo e hloekileng e na le mefokolo ea bohlokoa: e na le tšekamelo ea ho bola libakeng tse thata, haholo-holo ha e pepesehetse metsi a letsoai, li-acids, kapa litšila tsa indasteri. Ha nako e ntse e ea, e hlahisa patina e tala (lesela la oxidation), e ka fokolisang thepa le ho senya ts'ebetso lits'ebetsong tse kang ts'ebetso ea metsing kapa ea lik'hemik'hale.
Li-alloys tsa Cu-Ni, ka lehlakoreng le leng, kopanya koporo le nickel (hangata 10-30% nickel, hammoho le tšepe e nyenyane le manganese) ho sebetsana le bofokoli bona. Motsoako ona o fetola thepa ea thepa, ho qala kaho hanyetsa ho corrosion ho hodimo. Nickel e etsa lera le sireletsang oxide e thibelang ho chesoa ha likoti, ho bola ha maphao le khoholeho ea mobu—esita le metsing a letsoai, a letsoai kapa a litšila tse tsoang liindastering. Sena se etsa hore Cu-Ni e be e loketseng lisebelisoa tsa leoatleng joalo ka likepe tsa likepe, lits'ebetso tsa metsi a leoatle, le liphaephe tsa oli tse lebopong la leoatle, moo koporo e hloekileng e ka senyehang kapele.
Matla a mechine ke sebaka se seng moo Cu-Ni e fetang koporo e hloekileng. Le hoja koporo e hloekileng e le ductile, ha e na matla a tsitsitseng a hlokahalang bakeng sa lisebelisoa tse phahameng tsa khatello ea kelello. Li-alloys tsa Cu-Ni, ka lebaka la likarolo tsa tsona tsa motsoako, li fana ka matla a holimo le ho thatafala, ho etsa hore li tšoanelehe bakeng sa likarolo tse boima tse kang lipompo, li-valve le li-tubes tse futhumatsang mocheso. Li boetse li boloka ho feto-fetoha ha maemo, ho lumella ho etsoa habonolo ntle le ho tela nako e telele.
Mabapi le conductivity ea mocheso le motlakase, koporo e hloekileng e ntse e etella pele, empa Cu-Ni e boloka conductivity e lekaneng bakeng sa litlhoko tse ngata tsa indasteri-ha e ntse e eketsa molemo oa bohlokoa oa ho hanyetsa kutu. Tekano ena e etsa hore Cu-Ni e be thepa ea khetho libakeng tseo ho tsona ts'ebetso le bophelo bo bolelele li leng bohlokoa.
Lihlahisoa tsa rona tsa Cu-Ni li etselitsoe ho ntlafatsa melemo ena. E fumaneha ka mefuta e fapaneng (lithapo, maqephe, methapo) le lipina tsa nickel, li entsoe ka nepo ho fihlela maemo a thata a indasteri. Ebang ke tsa boenjineri ba leoatleng, ts'ebetso ea lik'hemik'hale, kapa mechini ea indasteri, lihlahisoa tsa rona tsa Cu-Ni li fana ka ts'epahalo, bophelo bo bolelele, le litšenyehelo tse tlase tseo koporo e ke keng ea tšoana le eona. Khetha Cu-Ni bakeng sa lits'ebetso moo ts'ebetso ea maemo a thata e ke keng ea buisanoa - 'me u tšepe hore lihlahisoa tsa rona li tla feta tebello ea hau.
