Polyimide Nickel/Chromium Alloy Insulated Wire (Ni80/Cr20) is an electrical wire product from Goodfellow's extensive range of specialty wires. With 71 variations available, this wire combines a nickel/chromium alloy conductor with a polyimide insulation. The nickel/chromium alloy provides high temperature stability and corrosion resistance. Meanwhile, the polyimide insulation offers excellent dielectric properties and heat resistance. Polyimide Nickel/Chromium Alloy Insulated Wire (Ni80/Cr20) finds uses in aerospace wiring applications, high-temperature sensors, and other demanding electrical environments requiring durable, high-performance cabling.
