Thermal conductivity steps the capability of a steel to command heat. This property varies across different types of metal and is essential to consider in applications wherein high operating temperatures space common.

You are watching: Why is copper a good conductor of heat

In pure metals, thermal conductivity stays roughly the same with rises in temperature. However in alloys the thermal conductivity boosts with temperature.

Which steels Conduct warm The Best?

Common metals ranked by thermal conductivity

As you deserve to see, out of the more common metals, copper and aluminum have the greatest thermal conductivity when steel and also bronze have actually the lowest. Heat conductivity is a very important property as soon as deciding which metal to usage for a specific application. Together copper is great conductor the heat, it’s an excellent for warm exchangers, heat sinks, and even saucepan bottoms. Due to the fact that steel is a negative conductor the heat, it’s great for high-temperature settings like airplane engines.

Here room some essential applications which require metals that conduct heat well:

Heat ExchangersHeat SinksCookware

Heat Exchangers

A warmth exchanger is a common application where good thermal conductivity is important. Heat exchangers perform their project by transferring heat to achieve heating or cooling.

Copper is a popular choice for warmth exchangers in industrial facilities, waiting conditioning, refrigeration, hot water tanks and also under-floor heating systems. That is high heat conductivity permits heat to pass with it quickly. Copper has added properties preferable in warm exchangers consisting of resistance come corrosion, biofouling, stress and also thermal expansion.

Aluminum can additionally be provided in some heat exchanger applications as a an ext cost-effective alternative.

Heat exchangers are frequently used in the complying with situations:

Industrial Facilities

Heat exchangers in commercial facilities encompass fossil and also nuclear strength plants, chemistry plants, desalination plants and marine services.

In commercial facilities copper-nickel alloy is offered to construct the heat exchanger tubing. The alloy has good corrosion resistance which protects versus corrosion in saltwater environments. It also has an excellent biofouling resistance to avoid formation of algae and sea mosses. Aluminum-brass alloy has similar properties and also can be used as one alternative.

Solar heat Water Systems

Solar water heaters are a cost-effective means to heat water in which a copper tube is supplied to carry the solar thermal energy to the water. Copper is used because of copper’s high heat conductivity, resistance come air and water corrosion, and also mechanical strength.

Gas Water Heaters

Gas water heat exchangers transfer the heat generated by gas fuels to water. They’re common in residential and commercial boilers. For gas water heaters, copper is the wanted material since of the high thermal conductivity and also ease the fabrication.

Forced air Heating and also Cooling

Heat pumps using air have long been offered for residential and commercial heating. They job-related via air-to-air warm exchange with evaporator units. They have the right to be used in hardwood furnaces, boilers, and stoves. Again, copper is frequently used because that its high thermal conductivity.

Heat Sinks

Heat sinks are a kind of heat exchanger the transfers heat produced by an electronic or mechanical maker into a relocating coolant fluid. The fluid transfers the heat away from the device, enabling it come cool to the wanted temperature. Steels with high heat conductivity space used.

Computers use heat sinks to cool main processing devices or graphic processors. Heat sinks are additionally used in high power tools like strength transistors, lasers and light emitting diodes (LEDs).

Heat sinks room designed to maximize the surface ar area in call with the coolant fluid.

Aluminum alloys room the most usual heat sink material. This is since aluminum prices less 보다 copper. Yet copper is provided where higher levels of heat conductivity are needed. Some heat sinks use a combination aluminum fins through a copper base.


A more household use of steel with great thermal conductivity is in cookware. As soon as you’re heater up your food, friend don’t want to wait every day. That is why copper is used in the bottoms of high-quality cookware because the metal rapidly conducts the heat and also spreads that evenly throughout its surface.

However, if you’re on a budget plan you can use aluminum cookware as an alternative. It might take a small longer to warmth up your food, but your wallet will say thanks to you because that it!
