Nickel Chrome NiCr resistance alloys are high-resistance materials typically used in applications with maximum operating temperatures up to 1,250°C. The NiCr resistance heating wire is always used in furnace as heating elements - NiCr.

These Nickel Chrome alloys are known for their higher mechanical strength at temperatures compared to Iron Chrome Aluminum (FeCrAl) alloys as well as their higher creep strength. NiCr alloys also remain more ductile when compared to Iron Chrome Aluminum alloys after extended periods at temperature. A dark Chromium Oxide (Cr2O3) is formed at high temperature which is susceptible to spalling, or flaking, causing potential contamination depending on the application. This oxide does not have electrical insulation properties like the Aluminum Oxide (Al2O3) of Iron Chrome Aluminum alloys. Nickel Chrome resistance alloys exhibit good corrosion resistance with exception to environments where sulfur is present.

HT resistance heating wire offers a variety of Nickel Chrome alloys and keeps the most common in inventory. Magnetic material heating treatment must be used NiCr heating wire as furnace heater. FeCrAl is not suitable for this area. If any inquiry, please free contact HT NiCr wire engineer.
