METALLIC 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 50-1425°C (120-2600°F).

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

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.
