Nichrome Cr20Ni80 High-Temperature Resistance Wire | 1200°C Rated for Industrial Heating & Corrosive Environments

Description

Nichrome Cr20Ni80 resistance wire delivers unmatched heat resistance (up to 1200°C), superior oxidation protection, and compliance with ASTM/GB standards. Ideal for furnaces, aerospace, and chemical processing.

Product Overview

Nichrome Cr20Ni80 resistance wire is a premium nickel-chromium alloy engineered for extreme thermal and corrosive applications. With 20–23% chromium (Cr) and 75–80% nickel (Ni), this alloy forms a robust chromium oxide (Cr₂O₃) layer at high temperatures, ensuring exceptional resistance to oxidation, sulfidation, and chlorine-induced corrosion. Its optimized electrical resistivity (1.09–1.14 μΩ·m at 20°C) guarantees stable performance in industrial heaters, thermocouples, and semiconductor equipment, even under cyclic heating conditions.

The alloy’s mechanical strength (≥650 MPa tensile strength) and ductility (≥20% elongation) enable seamless fabrication into coils, mesh, and precision components. Compliant with ASTM B603, GB/T 1234-2012, and DIN 17470, Nichrome Cr20Ni80 meets stringent global standards, making it ideal for Middle Eastern oil refineries, Southeast Asian electronics plants, and European aerospace systems. Its high melting point (1400°C) and low thermal expansion coefficient (18×10⁻⁶/°C) ensure reliability in environments ranging from industrial furnaces to household appliances.

FAQs

Q1: What is the maximum operating temperature for Nichrome Cr20Ni80?
A: Up to 1200°C in oxidizing atmospheres. For reducing environments (e.g., hydrogen), limit to 1000°C to prevent embrittlement.

Q2: Can Nichrome Cr20Ni80 replace FeCrAl alloys?
A: Yes, in applications requiring superior oxidation resistance and stable resistivity. However, FeCrAl may offer better cost efficiency in non-corrosive settings.

Q3: Is welding feasible for this alloy?
A: Yes, using TIG or laser welding. Post-weld annealing at 800°C restores oxide layer integrity.
