Ready-made metallic heating elements made from wire or strip in Kanthal iron-chromium-aluminium alloys or NikrKanthal 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 1425C (2600F). 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 1250C (2282F) othal nickel-chromium alloys for element temperatures between 50 - 1200C Element types.
