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.
