Nickel Chromium Alloy 40 Kuj Ribbon Ni40Cr20 Fais Rhaub Hlau
Nickel Chromium Resistance Alloy Resistohm 40 Kuj Zoo Ribbon Ni40Cr20 Fais Rhaub Hlau
Ni400cr20Yog ib qho tsis muaj pakib-chromium alloy (nicr alloy (nicr alloy) rau kev siv ntawm kub txog 1100 ° C (2010 ° F). Lub alloy yog tus cwj pwm los ntawm kev tiv taus loj thiab zoo oxidation tsis kam. Nws muaj cov qauv ua tau zoo tom qab siv thiab zoo heev Veldability.
Cov ntawv thov raug rau NI40cr20 yog hmo ntuj tso cua sov, kev kho cua sov, cov dej sov hnyav rheostats thiab kiv cua tso cua sov. Lub alloy tseem siv rau kev kub kub xaim thiab cov hlua ntxhua tso pa tawm, cov ntaub pam vov, lub tsheb cua sov thiab cua sov, tsim tawm.
