Product Description

0.8mm Nicr3020 Wire Isa-Chrom30 Ni30cr20 Resistance Wire for Sealer


(Common Name: Ni30Cr20,  N3, HAI-NiCr 30, Resistohm 30,30-20 Ni-Cr )

Nicr3020 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 Nicr3020  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.
