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 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 Etc., e ka fetola sebopeho, mefuta ea mocheso le boemo ba ho bola ha metastable, hape e ka ntlafatsa likarolo tse ling tsa 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.
