Cupronickel strip ke motsoako oa koporo o nang le nickel e le karolo ea mantlha ea alloying. Meqathatso ea koporo-nickel e thehiloeng holim'a li-alloys tsa koporo-nickel tse nang le likarolo tsa boraro tse kang zinki, manganese, aluminium, joalo-joalo li bitsoa li-zinc-nickel-nickel strips, manganese-nickel-nickel strips, le aluminium-nickel-nickel strips ho latela. Alloy ea koporo-nickel e na le khanyetso e ntle ea kutu, matla a mahareng, polasetiki e phahameng, 'me e ka sebetsoa ka khatello e chesang le e batang.
Lithapa tse tšoeu tsa koporo li arotsoe ka mekhahlelo e mehlano: likhoele tse tloaelehileng tsa koporo e tšoeu, likhoele tsa koporo tse tšoeu tsa tšepe, likhoele tse tšoeu tsa manganese, likhoele tse tšoeu tsa zinki le likhoele tse tšoeu tsa aluminium.
Mefuta e tloaelehileng ea koporo e tšoeu haholo-holo e na le limaraka tse 'nè tsa alloy tse kang B0.6, B5, B19, le B30. Tse sebelisoang hangata ke B19 le B30, 'me ho na le limaraka tse ngata letotong la maemo a Amerika. Lesela le lesoeu la koporo ke tharollo e tiileng e tsoelang pele e entsoeng ke Cu le Ni, e nang le lesela la li-cubic la sefahleho, joalokaha ho bontšitsoe setšoantšong sa 1-18. Ha mocheso o le ka tlase ho likhato tse 322, setšoantšo sa karolo ea koporo-nickel se na le sebaka se batlang se pharaletseng sa mocheso oa ho senyeha ha metastable, ho eketsa likarolo tsa boraro tse kang Fe, Cr, Sn, Ti, Co, Si, Al ho Cu-Ni alloy. Joalo-joalo, e ka fetola sebopeho, mefuta ea mocheso le boemo ba ho bola ha metastable, hape e ka ntlafatsa thepa e itseng ea alloy. Sejo se tloaelehileng sa koporo se tšoeu se na le serame se setle le se chesang se sebetsang hantle. E ka sebetsoa hantle ka libopeho tse fapaneng joalo ka lipoleiti, likhoele, li-tubes, lithupa, libopeho le likhoele. Ts'ebetso e ntle ea welding, e ka sebelisoa bakeng sa brazing e bonolo le e thata, welding ea arc e sirelelitsoeng ka khase le welding ea ho hanyetsa, joalo-joalo; tshebetso ya ho seha ke 20% ea koporo e sehang mahala HPb63-3. Letlapa le tloaelehileng la koporo e tšoeu le na le matla a ho thibela kutu, matla a mahareng, polasetiki e phahameng, e ka sebetsoa ka khatello e chesang le e batang, le thepa e ntle ea motlakase. Ntle le ho sebelisoa e le thepa ea meralo, e boetse e bohlokoa ho hanyetsa le thermocouple alloy.
