Ni80Cr20 Nichrome Alloy Wire for Industrial Electric Furnaces

The NiCr8020 alloy (material number 2.4869) is available in strips, sheets, tubes, and wires for furnace construction components and heating conductors. This nickel-chromium heating conductor alloy is designed for operating temperatures up to 1150°C and often includes rare earth additives for enhanced oxidation resistance, particularly in applications with frequent switching operations or wide temperature variations.

The alloy exhibits:

• High resistance to atmospheric corrosion at 20°C
• Excellent resistance to oxygen-containing gases and nitrogen-containing low-oxygen gases
• High carbonization resistance
• Low resistance to oxidizing and reducing sulfur-containing gases

• Nichrome Round Wire: Diameter 0.018mm-10mm
• Nichrome Ribbon: Width 5-0.5mm, thickness 0.01-2mm
• Nichrome Strip: Width 450mm-1mm, thickness 0.001-7mm
• Diameter: 1.5mm-8mm (coil), 8-60mm (rod)
