Nickel-chromium Alloys Electrothermal strip Cr20Ni80
Overview
Cr20Ni80 Nickel-Chromium Alloy Electrothermal Strip is a high-performance heating element engineered for extreme high-temperature environments. With a composition of 20% chromium (Cr) and 80% nickel (Ni), it offers exceptional oxidation resistance, ultra-stable resistivity, and extended service life. Widely applied in industrial furnaces, household appliances (e.g., ovens, heaters), and new energy systems, it delivers efficient and precise thermal management. Customizable dimensions and power outputs to meet diverse requirements.
