Nichrome
Nichrome is a non-magnetic alloy primarily composed of nickel and chromium, widely recognized for its high electrical resistance and excellent oxidation resistance at elevated temperatures.
Overview
Nichrome alloys, most commonly containing 80% nickel and 20% chromium, are essential in automotive applications requiring reliable heat generation. When heated, the material forms a protective layer of chromium oxide that prevents further degradation, making it ideal for components exposed to extreme thermal cycling. In the automotive sector, it is vital for emissions control in oxygen sensors and for passenger comfort in heating systems. As the industry shifts toward electric vehicles, Nichrome is increasingly utilized in high-voltage PTC heaters and cabin climate control modules.
