Characteristics

Metallic heating element alloys

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 oxidation 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. Compare weight and cost for Kanthal^® FeCrAl alloys with NiCr alloys
