Product Description

 OhmAlloy104A
(Common Name: Ni35Cr20,Chromel D, Nikrothal 40, N4, HAI-NiCr 40, Tophet D, Resistohm 40, Cronifer 3,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. It has a lower price and a higher cofficient of resistance. Therefore, it is very suiable for home appliances.
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.
