Product Description
0.5mm*5mm Ni30Cr20 flat wire nickel chrome 30/20 alloy for sealer heating strip
OhmAlloy104B
(Common Name: Ni30Cr20,Nikrothal 30, N3, HAI-NiCr 30, Resistohm 30,30-20 Ni-Cr,Nikrothal 3.)
OhmAlloy104B 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 OhmAlloy104B 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.
