I-Nickel Chromium Ukumelana ne-Alloy Resonohm 40 Ukumelana Ribbon NI40CR20 Electric herter wire
I-NI40CR20yi-auntenitic nickel-chromium alloy (i-nicr alloy) yokusebenzisa amazinga okushisa aze afike ku-1100 ° C (2010 ° F). I-alloy ibonakala ngokumelana okuphezulu kanye nokuphikiswa okuhle kwe-oxidation. Inokukhohlisa okuhle ngemuva kokusebenzisa futhi i-wallality enhle kakhulu.
Izicelo ezijwayelekile ze-NI40CR20 zingama-heater esitoreji sasebusuku, ama-hightover heater, ama-rheostats asebenza kanzima kanye nabashisi abalandeli. I-alloy nayo isetshenziselwa ukufudumeza izintambo kanye nokushisa ngezintambo ekuguqukeni nasezintweni ze-de-icing, izingubo zikagesi namaphakethe, izihlalo zemoto, ama-baseboard ama-heater, ukumelana.
