Product Description

High Quality Nichrome Nikrothal 70 Heating Element Ni70cr30 Nicr 70/30 Wire for Resistor

Ni70Cr30 is an austenitic nickel-chromium alloy suitable for temperature applications up to 1250°C. High chromium content (30% in average) provides very good life time, especially in the furnace applications. Ni70Cr30 is characterized by high resistivity, good oxidation resistance, good ductility after use and excellent weldability.

Ni70Cr30 is used for electric heating elements in industrial furnaces. Typical applications are: electric and enamelling furnaces, storage heaters, furnaces and kilns with a changing atmospheres.
