Nichrome Cr20Ni35 resistance wire delivers reliable heat resistance (up to 1100°C), corrosion protection, and compliance with global standards. Ideal for industrial furnaces, automotive systems, and energy equipment.
Nichrome Cr20Ni35 resistance wire is a nickel-chromium alloy optimized for high-temperature performance in cost-sensitive industrial applications. With 18–21% chromium (Cr) and 34–37% nickel (Ni), this alloy forms a durable chromium oxide (Cr₂O₃) layer, providing robust resistance to oxidation and moderate corrosion in sulfur or chlorine-rich environments. Its balanced composition ensures stable electrical resistivity (1.04–1.10 μΩ·m at 20°C) and thermal conductivity, making it ideal for heating elements in industrial furnaces, automotive sensors, and consumer appliances.
Designed for temperatures up to 1100°C in oxidizing atmospheres and 900°C in reducing conditions, Nichrome Cr20Ni35 outperforms lower-grade alloys in cyclic heating scenarios. Compliant with ASTM B344, EN 10095, and JIS C2520, it meets stringent requirements for European aerospace, Southeast Asian electronics, and Middle Eastern petrochemical industries. The alloy’s tensile strength (≥550 MPa) and elongation (≥30%) allow easy fabrication into coils, ribbons, and precision components, while its cost-efficiency makes it a preferred choice for large-scale manufacturing.

ASTM B344: Nickel-Chromium Electrical Heating Alloys
EN 10095: Heat-Resisting Steels and Alloys
JIS C2520: Japanese Resistance Alloy Standards
Industrial Furnaces: Heating elements for steel annealing, glass tempering, and ceramic kilns.
Automotive: Glow plugs, EGR valves, and battery thermal management systems.
Energy Sector: Heating coils in boilers, solar thermal plants, and geothermal systems.
Consumer Electronics: Cost-efficient coils for kitchen appliances and HVAC systems.
Chemical Processing: Moderate-corrosion environments requiring cyclic heating.
Q1: How does Nichrome Cr20Ni35 compare to higher-nickel alloys like Cr20Ni80?
A: Cr20Ni35 offers a lower nickel content for cost efficiency while maintaining adequate oxidation resistance up to 1100°C, ideal for budget-conscious industrial projects.
Q2: Is this alloy suitable for marine environments?
A: Limited suitability. While it resists oxidation, prolonged exposure to saltwater may require additional coatings or higher-nickel alternatives.
Q3: Can it be welded or formed into complex shapes?
A: Yes, its ductility allows cold-forming and welding via TIG or resistance methods. Post-weld annealing at 750°C enhances corrosion resistance.
