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 elements are used in an electric heater filament?
The heating element in electric heaters and irons is made from an alloy of nickel and chronium called nichrome. It is usually made in the form of wire. The wire is often wound around a flat sheet of mica for support. Mica is a thin layered mineral that can withstand high temperatures.
Alloys are used in electrical heating devices rather than pure metals. Give reason.?
Alloys are used rather than pure metals in electrical heating devices since they have low electrical conductivity and also a low melting point. Usually the alloys don't have a single melting point; they have a range of melting points. The temperature at which melting begins is called the SOLIDUS and the temperature at which melting is complete is called the LIQUIDUS.Student
What types of energy does a coffee machine use?
A coffee machine typically uses electrical energy to power its heating elements and pumps. Some coffee machines may also use kinetic energy (for manual espresso machines) or potential energy (for stove-top espresso makers).
What is the change of energy in a toaster?
The change in energy in a toaster is usually in the form of electrical energy being converted to heat energy by the heating elements inside the toaster. This heat energy is then used to toast the bread or other foods placed inside the toaster.
Is porcelain a metal?
No, porcelain is not a metal. It is a type of ceramic material that is usually made by heating clay or other materials at high temperatures. Metals are elements that typically have high electrical conductivity and are malleable.
Name the conductor normally used in heating appliances?
The conductor normally used in heating appliances is usually a nichrome wire. Nichrome is an alloy of nickel and chromium that has high electrical resistance, making it ideal for converting electrical energy into heat efficiently.
What is the purpose of generating electricity?
Electrical generators usually are used to generate electricity.
Can you use electrical tape inside a microwave?
Generally speaking, electrical tape, which is usually a polyvinyl, may be subject to heating inside the oven. If so, it could melt and possibly catch fire.
Which groups of elements would most likely be used for electrical wires?
Electrical wires are usually made from metals.
Display devices are usually classified as what type of devices?
Display devices are usually classified as output devices.
What is auxiliary heat?
Usually a backup heating unit. For instance in a heat pump when the temperature drops below the temperature where the heat pump cannot extract heat from the existing air electric heating elements kick in.
What's the average price for central heating service?
The average price for a central heating service depends on several factors, for example if this heating service is based on electricity, oil or gas. It also depends on the area one lives in. People usually pay around $300 a month for electrical heating, or $75 - $150 a month for gas heating.
How does a missile explod?
A smaller missile will usually detonate by means of an electrical impulse sent by a contact device, while larger cruise missiles and nuclear devices often contain sensing devices that are programmed to detonate when they are at a certain distance from the target. Tiny devices such as mortar shells and RPG rounds usually have blasting caps that are impact sensitive.
