Ntawm cov tooj liab alloys, cupronickel yog dav siv nyob rau hauv shipbuilding, roj av, tshuaj lom neeg kev lag luam, kev tsim kho, hluav taws xob fais fab, precision instruments, cov cuab yeej kho mob, suab paj nruag thiab lwm yam sectors raws li corrosion-resistant structural qhov chaw. Vim nws cov corrosion kuj zoo heev thiab yooj yim molding, ua thiab vuam, cupronickel kuj muaj cov khoom siv hluav taws xob tshwj xeeb, uas tuaj yeem siv los ua cov khoom tiv thaiv, cov khoom siv thermocouple thiab cov xaim them nyiaj. Tsis yog-kev lag luam cupronickel feem ntau yog siv los ua cov khoom siv dai kom zoo nkauj.
