Because of its versatility, copper is often found in cookware, computers, and heating systems. While not as strong as copper, aluminum is still very good at conducting heat. In addition to this, aluminum is used in LED lights as a heat sink because it helps the lights work more efficiently without overheating. Brass is a very tough metal and can be heated to temperatures as high as 1,degrees Fahrenheit. This alloy metal is a mix of copper and zinc which helps it to conduct heat well.
Because of its strong heat absorption, brass is also able to instantly destroy germs, making it a popular metal to use for doorknobs and similar items that are often touched.

Computers use heat sinks to cool central processing units or graphics processors. Heat sinks are also used in high power devices like power transistors, lasers and light emitting diodes LEDs.
Aluminum alloys are the most common heat sink material. This is because aluminum costs less than copper. However copper is used where higher levels of thermal conductivity are needed.
Some heat sinks use a combination aluminum fins with a copper base. A more household use of metal with good thermal conductivity is in cookware. That is why copper is used in the bottoms of high-quality cookware because the metal rapidly conducts the heat and spreads it evenly across its surface. It may take a little longer to heat up your food, but your wallet will thank you for it!

Here are some important applications which require metals that conduct heat well: Heat Exchangers Heat Sinks Cookware Heat Exchangers A heat exchanger is a common application where good thermal conductivity is important.
Heat exchangers are commonly used in the following situations: Industrial Facilities Heat exchangers in industrial facilities include fossil and nuclear power plants, chemical plants, desalination plants and marine services. Solar Thermal Water Systems Solar water heaters are a cost-effective way to heat water in which a copper tube is used to transfer the solar thermal energy to the water.

Thermal conductivity is the term that describes how quickly a material absorbs heat from areas of high temperature and moves it toward areas of lower temperature. The best heat-conducting metals have high thermal conductivity and are useful for many applications, such as cookware, heat exchangers, and heat sinks.
On the other hand, metals with a lower rate of heat transfer are also useful where they can act as a heat shield in applications that generate large amounts of heat, such as airplane engines. With one of the lowest thermal conductivities for a metal alloy, stainless takes much longer to conduct heat away from a source than, say, copper. This means that a pot made of stainless would take much longer to heat up food than a copper-bottom pot though stainless has other benefits.
Steam and gas turbines in power plants use stainless steel because of its heat resistance, among other properties. In architecture, stainless steel cladding can resist high temperatures longer, keeping buildings cooler in sunlight. While aluminum has a slightly lower thermal conductivity than copper, it is lighter in weight, cheaper, and easier to work with, making it a better choice for many applications. For example, microelectronics such as LEDs and laser diodes use tiny heat sinks with aluminum fins that project into the air.
