Nichrome 80 Resistance Wire

Nichrome 80 (80% Nickel / 20% Chromium) is a high-performance nickel-chromium alloy trusted worldwide as the standard for electric resistance heating. With a maximum continuous operating temperature of up to 1200°C (2190°F) and a melting point of 1400°C (2550°F), it thrives in demanding high-heat environments.

Standout features include:

Exceptional oxidation and corrosion resistance from a durable, self-healing chromium oxide layer—ideal for frequent thermal cycling without flaking or scaling.
Extremely low temperature coefficient of resistance for stable output, quicker heat-up, even temperature profiles, and consistent performance over time.
Negligible resistance drift during long service life.
Outstanding mechanical properties that prevent sagging, distortion, shrinkage, or uneven stretching in coiled or formed elements—ensuring precise, reliable designs and maximum longevity.

Perfect for hot wire foam cutters, industrial furnaces, household appliances, precision resistors, and other heating applications where durability, efficiency, and stability matter most.
