1Furnace Heating Element Wire

Electric Oven Wire is a type of high resistance electrical wire. The wire resists the flow of electricity, and converts the electrical energy into heat.

 

Application for resistance wire includes resistors, heating elements, electric heaters, electric ovens, toasters, and many more.

 

Nichrome, a non-magnetic alloy of nickel and chromium, is commonly used to make resistance wire because it has a high resistivity and resistance to oxidation at high temperatures. When used as a heating element, resistance wire is usually wound into coils. One difficulty in using Electric Oven Wire is that common electrical solder will not stick to it, so the connections to the electrical power must be made using other methods such as crimp connectors or screw terminals. 

 

FeCrAl, a family of iron-chromium-aluminum alloys used in a wide range of resistance and high-temperature applications is also used in the form of resistance wires.
