Constantan hlau txhais
Kev tiv thaiv alloy nrog kev tiv thaiv kev cuam tshuam thiab kub ua kom tsis taus nrog lub tiaj tus tiv thaiv / qhov ntsuas kub nyhiab ntau dua li cov "manganins".Cuni44 Alloy Hlau kuj qhia tau zoo dua corrosion tsis kam dua li tus txiv neej ganins. Siv zoo li raug txwv rau AC circuits. Cuni44 / cuni40 / cuni45 Constantan Tooj Liab Nickel xaim kuj tseem yog qhov tsis zoo ntawm hom tsis zoo ntawm hom tsis zoo nrog cov hlau ua tus cwj pwm zoo; Hom J thermohoto yog siv hauv kev kho cua sov. Tsis tas li, nws yog lub ntsiab lus tsis zoo ntawm hom t Thermocouple nrog OfHC Tooj liab qhov zoo; Ntaus tlocouples yog siv ntawm cryogenic kub.
