Product Description
Engineered for superior high-resistance applications in heating elements and industrial furnaces, NiCr 2080 Resistance Alloy 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.

—— China Leading Resistance Heating Alloy Wire Manufacturer
Yes, NiCr 2080 is the Chinese standard designation for Nichrome 80:20 (Ni80Cr20) resistance heating alloy wire, containing approximately 80% nickel and 20% chromium. It is one of the most widely used high-resistance heating elements worldwide.
Ni80Cr20 wire is extensively used in industrial electric furnaces, kiln heating elements, foam cutting machines, ceramic kilns, laboratory muffle furnaces, household appliances (toasters, hair dryers), automotive seat heaters, and high-temperature resistors.
Our NiCr 2080 (Nichrome 80:20) resistance wire can continuously operate at 1200°C (2192°F) and withstand short-term peaks up to 1250°C, making it ideal for high-temperature industrial heating applications.
Compared to Ni60 (Cr15) series, Ni80Cr20 offers higher resistivity, better oxidation resistance at 1200°C+, and longer service life. Compared with FeCrAl (0Cr25Al5), nichrome 80:20 has superior high-temperature corrosion resistance and is more cost-effective in most non-sulfur environments.
All our NiCr 2080 resistance alloy wires are manufactured under ISO 9001:2015 and come with RoHS, REACH compliance, and full material test certificates (MTC) showing chemical composition and physical properties.
Our production base is located in Jiangsu Province – the heart of China’s special alloy and resistance wire manufacturing cluster, only 2 hours from Shanghai port.
We offer flexible MOQ: 5 kg for standard sizes, 20–50 kg for custom diameters. Trial orders are welcome for new customers.
Standard sizes: 7–15 days; custom diameters: 15–30days. Express delivery and sea+air combined shipping options available.
