Cupronickel los yog tooj liab-nickel yog ib qho alloy ntawm tooj liab uas muaj nickel thiab ntxiv dag zog, xws li hlau thiab manganese. Cupronickel tiv taus corrosion hauv dej hiav txwv vim tias nws cov khoom siv hluav taws xob tau hloov kho kom tsis txhob cuam tshuam nrog dej hiav txwv. Vim li no, nws yog siv rau cov kav dej, cov khoom siv hluav taws xob, thiab cov condensers hauv cov dej hiav txwv, nrog rau cov khoom siv hauv hiav txwv, thiab qee zaum rau cov kiv cua, crankshafts, thiab hulls ntawm tus nqi kim tug nkoj, nkoj nuv ntses, thiab lwm yam nkoj ua haujlwm.
Tooj liab nickel 70-30% 715yog ib qho ntawm feem ntau corrosion-resistant thiab ruaj tooj liab- puag alloys rau condenser thiab tshav kub exchanger raj hauv dej hiav txwv. Nyob rau hauv siab - siab, siab - qhov kub ntawm qhov chaw nres tsheb, tooj liab-nickel 70-30% cov raj siv rau hauv feedwater heaters tsis hais hom raj siv nyob rau hauv lub ntsiab condensers.
