Formula: Ni 80/Cr 20
Form: Insulated Wire
Material: Nickel/Chromium
Commodity: Alloys
Insulation:
Polyimide
Polyimide-Insulated Nickel/Chromium Alloy Wire (Ni80/Cr20) integrates the high-temperature resistance and oxidation stability of nickel-chromium alloy with the dielectric reliability and chemical resistance of polyimide insulation. It is designed for heater elements, resistive load components, and high-temperature electrical connections. Industries such as aerospace, process heating, and materials testing use it in furnaces, jet engine sensors, and laboratory heating rigs. Specific applications include precision resistance heaters, high-load rheostats, and temperature control wiring. In research, it supports studies on alloy oxidation resistance, electrical stability under thermal stress, and insulation-coating performance in oxidizing atmospheres. The insulated wire’s blend of mechanical durability and high-temperature capability ensures long-term performance in critical applications.
