Resistance heating wire and strip
Resistance heating wire and resistance heating strip in iron-chromium-aluminium (FeCrAl) alloys and nickel-chromium (NiCr) alloys for the manufacturing of electric heating elements.
Using Kanthal FeCrAl alloys instead of NiCr alloys result in both weight-saving and longer element life. Compare Kanthal® FeCrAl alloys with NiCr alloys
Kanthal® and Alkrothal® FeCrAl resistance heating alloys
Resistance heating alloys based on iron-chromium-aluminium for maximum element temperature of 1425°C (2600 °F). Kanthal® and Alkrothal® resistance heating alloys are characterized by high resistivity and capability to withstand high surface load.
Nikrothal® NiCr resistance heating alloys
Nickel-chromium-based resistance heating alloys suitable for element temperatures up to 1250°C (2282°F). Nikrothal® resistance heating alloys are characterized by very good mechanical properties in the hot state as well as good oxidation and corrosion properties.
