Product Description
Engineered for superior high-resistance applications in heating elements and industrial furnaces, Cr10Ni90 NiCr Alloy Heating Resistance Wire delivers reliable performance up to 1250°C. This austenitic alloy with 10% chromium content ensures extended service life in furnace applications, immune to "green rot" and compatible with both reducing/oxidizing atmospheres.
Featuring high resistivity (1.18μΩ·m), exceptional oxidation resistance, and cold-forming capability with low thermal expansion (14.2×10⁻⁶/℃), it is the optimal solution for industrial furnace windings, precision resistance coils, and high-temperature heating systems.
