Ready-made metallic heating elements made from wire or strip in Kanthal iron-chromium-aluminium alloys or Nikrothal nickel-chromium alloys for element temperatures between 50 - 1200°C Element types.
Kanthal and Alkrothal FeCrAl alloys are characterized by high resistivity and capability to withstand high surface load. They can be used at maximum element temperature of 1425°C (2600°F).
The NiCr-based alloys are characterized by very good mechanical properties in the hot state as well as good oxdiation and corrosion properties. They are suitable for element temperatures up to 1250°C (2282°F)
Using Kanthal FeCrAl alloys instead of NiCr alloys results in both weight-saving and longer element life, leading to considerable cost savings.
