Nickel-chromium Alloys Electric furnace wire Cr20Ni80

Overview

Cr20Ni80 Nickel-Chromium Alloy Electric Furnace Wire, with 80% high nickel content, sets the standard for high-temperature oxidation and corrosion resistance. Operating continuously at 1200°C (short-term peak 1300°C) and featuring low resistivity (1.04μΩ·m), it is engineered for household appliances (ovens, water heaters), industrial kilns, and renewable energy systems, delivering energy-efficient and ultra-durable heating performance.
