Cr20Ni80 strip, a precision-engineered nickel-chromium alloy, delivers unmatched performance in high-temperature and corrosive environments. With a composition of 80% nickel and 20% chromium, this alloy excels in applications demanding oxidation resistance up to 1,200°C (2,192°F), superior electrical resistivity, and prolonged thermal stability. Its unique microstructure ensures minimal embrittlement even after prolonged exposure to cyclic heating, making it ideal for industrial heating elements, aerospace thermal systems, and precision electrical components.
The alloy’s low temperature coefficient of resistance guarantees consistent performance in variable thermal conditions, while its exceptional formability allows for seamless fabrication into complex geometries. Compliant with ASTM B344, DIN 17470, and IEC 60240 standards, Cr20Ni80 strip is rigorously tested to meet global quality benchmarks. Industries across Europe, Southeast Asia, and the Americas rely on its durability in critical applications such as furnace windings, resistance welding electrodes, and nuclear reactor instrumentation.
Cr20Ni80 strip is available in customized thicknesses (0.05–5.0 mm) and widths (10–500 mm), with optional surface finishes (annealed, cold-rolled, or polished) to meet specific operational requirements.

Global Compliance: Meets ASTM, DIN, and IEC standards for cross-border procurement.
Q: Can Cr20Ni80 strip replace Kanthal alloys in heating elements?
A: Yes, its higher nickel content offers better oxidation resistance and longer service life in sulfur-rich environments.
Q: What surface finishes are available for export markets?
A: Custom options include 2B cold-rolled finish for electronics or bright annealed surfaces for decorative thermal systems.
Q: Is vacuum annealing recommended for aerospace applications?
A: Absolutely. Vacuum annealing eliminates surface carburization, critical for high-purity thermal management.
