0Cr23Al5 Electrical Resistance Wire For Heater Resistor Furnaces
What metal is a heating element made of?
Heating elements found in common appliances are made from metallic resistance alloys such as Fe-Cr-Al and Ni-Cr(Fe).
They have the ability to produce temperatures hot enough to get the element to glow red hot, in the neighborhood of 1112°F (600°C) and above.
