Ohmalloy 104A
(Common Name: Ni35Cr20,Chromel D, Nikrothal 40, N4, HAI-NiCr 40, Tophet D, Resistohm 40, Cronifer Ⅲ,Chromex,35-20 Ni-Cr, Alloy D, NiCr-DAlloy 600,Nikrothal 4,MWS-610,Stablohm 610.)
OhmAlloy104A is a nickel-chromium alloy (NiCr alloy) characterized by High resistivity, good oxidation resistance, very good form stability, good ductility and excellent weldability. It is suitable for use at temperatures up to 1100°C.
Typical applications for OhmAlloy104A are used in night-storage heaters, convection heaters, heavy duty rheostats and fan heaters. And also used for heating cables and rope heaters in defrosting and de-icing elements, electric blankets and pads, car seats, baseboard heaters and floor heaters, resistors.
