Electric oven burners

If I understood correctly that anything that heats with electric is made up of the same material.

A heating element converts electricity into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element.



Most heating elements use Nichrome 80/20 (80% nickel, 20% chromium) wire, ribbon, or strip. Nichrome 80/20 is an ideal material, because it has relatively high resistance and forms an adherent layer of chromium oxide when it is heated for the first time. Material beneath this layer will not oxidize, preventing the wire from breaking or burning out.
Resistance wire: may be wire or ribbon, straight or coiled. Used in common items such as toasters and hair dryers, furnaces for industrial heating, floor heating, roof heating, pathway heating to melt snow, dryers etc. Most common wires are from the following classes

Kanthal (FeCrAl) wires
Nichrome 80/20 wire and strip
Cupronickel (CuNi) alloys for low temperature heating
