Copper-nickel Sawb
Khoom Taw Qhia
Copper-nickel alloy yog ua los ntawm tooj liab, hlau, npib tsib xee, zinc thiab kab kawm, los ntawm kev ua haujlwm los ntawm cov khoom siv, kub dov, txias dov, kho cua sov, ntxuav qhov chaw, txiav, xov, ntim thiab lwm yam txheej txheem.cov khoom muaj ib tug zoo nkauj gloss, zoo heev kub thiab txias workability, ductility, corrosion kuj, qaug zog kuj, siab yooj, zoo hluav taws xob thiab txhua yam khoom thiab shielding kev ua tau zoo.Nws yog dav siv nyob rau hauv kev tsim cov ntaub ntub dej thiab corrosive media hauv kev ua haujlwm ntawm cov khoom siv, cov khoom siv tau yooj yim, cov cuab yeej precision, kev lag luam kev sib txuas lus, kua siv lead ua oscillation element vaj tsev, khoom siv kho mob, kev tsim kho, cov cuab yeej cua thiab cov khoom siv, thiab cov khoom siv niaj hnub thiab lwm yam. .
