I-Nickel Chromium Alloy 40 Resistance Ribbon Ni40cr20 ngocingo lwesifudumezi soMbane
I-Nickel Chromium Resistance Alloy Resistohm 40 Resistance Ribbon Ni40cr20 iheater yombane
Ni40Cr20yi-austenitic nickel-chromium alloy (NiCr alloy) yokusetyenziswa kumaqondo obushushu ukuya kwi-1100°C (2010°F). I-alloy ibonakaliswe ngokumelana okuphezulu kunye nokuchasana kakuhle kwe-oxidation. Ine-ductility elungileyo emva kokusetyenziswa kunye ne-weldability ebalaseleyo.
Usetyenziso oluqhelekileyo lweNi40Cr20zizifudumezi zokugcina ubusuku, izifudumezi ze-convection, ii-rheostats ezinzima kunye nezifudumezi zefeni. I-alloy isetyenziselwa ukufudumeza iintambo kunye nezifudumezi zentambo kwi-defrosting kunye ne-icing elements, iingubo zombane kunye neepads, izihlalo zeemoto, izifudumezi zebhodi kunye nezifudumezi zomgangatho, i-resistors.
