Nickel/Chromium Alloy Foil (Ni80/Cr20) - T 0.025mm 50mm x 50mm

Nickel/Chromium Alloy Foil (Ni80/Cr20) is a high-performance foil composed of 80% nickel and 20% chromium, valued for its excellent oxidation resistance, mechanical stability at elevated temperatures, and predictable thermophysical behavior. The alloy’s balance of nickel’s corrosion resistance and chromium’s oxidation protection enables reliable use in aerospace engine components, industrial furnaces, and high-precision electrical resistors. Its stable electrical resistivity and low thermal expansion rate make it a preferred choice for resistance heating elements, precision shunts, and thermal sensors. With a melting point above 1,400 °C, the foil withstands extreme environments without significant degradation, and its ability to maintain mechanical strength after prolonged exposure to high heat makes it ideal for demanding service conditions. In clean energy systems, Ni80/Cr20 has been developed for use in hydrogen fuel cell air compressor foils, benefiting from fine microstructures that enhance fatigue resistance. This material’s combination of heat tolerance, corrosion protection, and electrical stability ensures its continued importance in both traditional and emerging high-tech industries.
