Generally the Kanthal alloys are used.
<<>>
Depending on the temperature range that is needed, the heating element could be composed of; iron-chromium-aluminium, nickel-chromium, nickel-iron or copper-nickel. The maximum temperature range for each alloy is 1400 C, 1250 C, 600 C and 600 C respectively.

Which groups of elements would most likely be used for electrical wires?
Electrical wires are usually made from metals.
Why can you use electrical devices without getting shocked?
You can use electrical devices without getting shocked because they are designed with protective insulation and grounding systems that prevent electric current from flowing through you. In addition, electrical devices are designed with safety features such as circuit breakers that can interrupt the flow of electricity in case of a fault. It is important to always follow safety guidelines and use devices as intended to avoid the risk of electric shock.
Why is heating a home with natural gas usually the cheapest option compared to heating with electricity?
There are many reason why natural gas is usually a cheaper option for heating when compared to heating with electricity. The biggest reason is heating with therms is cheaper than kilowatts.
What is considered an open fire?
An "open flame" refers to flame, usually used as a heating source, that is directly exposed to the outside elements, or often the object to be heated. Examples would include a Bunsen burner, a bonfire, or in some cases grills. The opposite would include heating elements that do not directly openly expose the flame, such as old stoves or heating elements.
What are electrical outlets made of?
Electrical outlets are typically made of a combination of thermoplastics, metal contacts, and internal wiring components. The outer casing is usually made of fire-resistant materials to ensure safety during operation. The metal contacts inside the outlet provide the connection point for electrical devices.
