Your question: Which material is best for making heating devices such as electric water heater?

Nichrome: Most resistance wire heating elements usually 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.

Which material can be used as heating element?

The most common material used for the heating element is Nichrome. Nichrome is the alloy of the Nickel and chromium; in this alloy the nickel is 80% and the chromium is 20%. So, this alloy is called nichrome 80/20.

IMPORTANT:  Best answer: Which solids do not allow electricity to pass through them?

Which heating element is best for water heater?

The best elements are usually made of nickel and stainless steel and are known as ultra-low watt-density elements. They have a lower heat per sq. inch of a surface than the regular elements and are usually folded back.

Which property of heating element is used in making electric heater?

Electric heater works on the principle of Joule’s Law of Heating and it normally made up of an alloy of Nickel (80%) and Chromium (20%) called Nichrome,it has a high resistance.

Which of these should be used for making a heater?

Nichrome is used for making the heating element of an electric iron. It has relatively high resistance and a high melting point.

Which material is used in electric heating?

Nichrome: Most resistance wire heating elements usually 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.

What material is an electric 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.

Which metal is used in water heaters?

Stainless steel used in domestic hot water heaters are most commonly made from only a few grades of stainless steel, typically types 304, 316L, 316Ti and 444. Stainless steel indirect water heater. Stainless steel is used in all different types of water heaters.

IMPORTANT:  Your question: What if everyone switched to electric cars?

Are all electric water heater elements the same?

There are three types: screw in, bolt in and clamp in. They all have different wattage ratings and can work on either 120 or 240 voltage. Check your state and local codes before starting any project.

Which is better copper or stainless steel heating elements?

Copper vs Stainless Steel. Heat transfers 25 times more readily through copper than stainless steel. Consequently, for the same amount of heat transfer, stainless steel heat exchangers need to be larger than copper heat exchangers, leading to a larger pressure loss. … Copper is also better with heat transfer.

Which material would you advise to use in electric heating devices Why?

Nichrome is the best material for heating elements. It is because the resistivity of the nichrome is more than the resistivities of the metals used to make it and it does not oxidise at higher temperature.

What are the characteristics of the material used as heating element in electric heating appliances?

The most important heating element characteristics are sufficient resistivity, high oxidation resistance, low-temperature coefficient of resistance, high toughness, and high melting point.

Can copper be used as heating element?

But copper also has shortcomings as a material for a heating element. As the temperature of a copper heating element increases, the electrical resistance increases at a rate which is undesirably high.

Which material is used for making the heating coil of an electric iron?

Nichrome is an ideal material for heating elements for an electric iron also because the oxide layer formed helps to protect the inner material from oxidizing which doesn’t let internal wires burn.

IMPORTANT:  Do electronics use electricity when they are off?
