NiCr35/20 Nichrome Electric Resistance Heating Wire for Heating
Elements (Common Name:Ni30Cr20,Nikrothal 30, N3, HAI-NiCr 30, Resistohm
30,30-20 Ni-Cr,Nikrothal 3.)
It 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 Ni30Cr20 are used in olid hot plates,open coil heaters in HVAC
systems,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,floor heaters and resistors.
