Iron-Chromium-Aluminium Alloy Electrical Resistance and Heating Element Wires, Ribbons, and Strips

Alloy Description

  • FeCrAl 125: Low-cost heating element used in toasters and other small appliances. Long life performance for element operating temperatures up to 1150 °C.
  • FeCrAl 135: Used as heating elements in hot plates, irons, electric furnaces, etc.. Improved hot strength compared to 125 grade.  Good for continuous element operating temperatures up to 1200 °C. Also used in resistor applications and heavy relay switches.
  • FeCrAl 145: Used for industrial furnaces, kilns and other high temperature applications. Long-life for continuous operating temperatures up to 1300 °C. Less increase in resistance on heating and higher oxidation resistance compared to other grades.

Condition of Supply

  • Bright Annealed;
  • Oxidised (Blue and Golden);
  • As Drawn
