Heating Elements

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 50-1425C (120-2600F).

Element types
We can manufacture metallic heating elements to any specifications and with short delivery times. Examples of element types are:
  • Coiled elements (i.e. spiral elements and edge-wounded elements)
  • ROB - Meander elements
  • Cartridge elements (i.e. bundle rod elements and cage elements)
  • Tubothal heating element

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 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).

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.
