Product Description
Engineered for superior high-resistance applications in heating elements and industrial furnaces, Cr20Ni80 Nickel Chromium Wire delivers reliable performance up to 1250°C. This austenitic alloy with 20% 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.

Product Process
Customer first and Best price offer
Cr20Ni80 (NiCr 80/20) is the most widely used high-resistance electrothermal alloy wire in the world, containing 80% nickel and 20% chromium. It is the standard material for industrial heating elements and high-temperature electric furnaces, offering excellent oxidation resistance up to 1200°C. We are a leading Cr20Ni80 nichrome wire manufacturer in China with 16+ years of factory experience.
Cr20Ni80 nichrome wire can continuously operate at 1200°C (2192°F) and withstand short-term peaks up to 1250°C, making it the first choice for industrial kilns, ceramic furnaces, and vacuum furnace heating elements.
DLX Alloy is one of the largest direct nichrome wire factories in China (located in Jiangsu Province). We supply authentic Cr20Ni80/NiCr 8020 resistance heating wire worldwide with mill test certificates, supporting custom diameters from 0.01mm to 12mm.
