Cr20Ni80 Wire: Nickel Alloy 1400℃ Melting Point Used In Industrial Furnaces

Cr20Ni80 nickel-chromium alloy wire is a high-performance resistive electric heating material, mainly composed of 80% nickel and 20% chromium, with a high melting point (about 1400°C-1450°C), and can operate stably at working temperatures up to 1200°C. The resistivity of this alloy wire is about 1.09μΩ·m at 20°C, and it can maintain a stable resistance value in a high-temperature environment. Its excellent oxidation resistance and corrosion resistance make it perform well in high-temperature oxidizing atmospheres, and it also has good processing properties and can be processed into wires of different diameters.
Cr20Ni80 alloy wire is widely used in industrial furnaces, electric heating elements, resistors, and high-temperature heating equipment, and is especially suitable for scenes that require long-term high-temperature stable operation. Its high melting point and good high-temperature stability make it an ideal material for industrial heating and household appliances.
