Heat sinks are not made of copper because it is too expensive to use. Copper is a better conductor of heat than aluminum, which means that the heat will be dissipated more quickly.
When you are designing a CPU, there are many factors to take into account. One of the most important is heat dissipation. Copper is a good material for heat sinks because it has high thermal conductivity and a low thermal expansion coefficient. However, copper is also expensive and heavy.
As a result, heatsinks are often made of aluminum or nickel-plated steel instead of copper.
What is a Heatsink?
A heatsink is a passive heat dissipation device that transfers the heat generated by an electronic or mechanical device to a fluid medium.
A heatsink is made up of a solid material, usually metal, which has high thermal conductivity. The metal is shaped in such a way that it has many thin fins which increase the surface area. The fins are usually designed in such a way that they are aligned with the airflow pattern to maximize heat dissipation and minimize turbulence.

How do Heatsinks Work?
Heat sinks are components that are found in many electronic devices. They are used to dissipate heat from the system and cool it down.
Heatsinks work by transferring the heat from one place to another. They use thermal conductivity and convection to do so. Heatsinks are typically used in electronics to help maintain a stable temperature.
Why Engineers Choose Not to Make Heat Sinks from Copper
Copper is a great conductor of heat because it has a high thermal conductivity. It is also light and malleable, which makes it easy to form into shapes.
It doesn’t, however, have the best corrosion resistance. This means that over time, copper will eventually corrode and need to be replaced. It also doesn’t have the best thermal stability at extreme temperatures.
Pros and Cons of Using Copper as Your Material
Copper is a metal that has been used for centuries and it has some really good properties that make it a desirable material. Copper is an excellent conductor of heat.
The cons of using copper as your material are that it can corrode over time, which means you have to take care of it and clean it regularly. Another con is that copper reacts with other metals and this can cause discoloration or tarnish on the surface of the copper.

Conclusion
Copper is a type of metal with a high thermal capacity. This means that it takes a long time to release heat. For this reason, copper heatsinks are not used in most cases.
FAQ
Are heat sinks copper?
No, heatsinks are not made out of copper. Copper has high thermal conductivity and is too expensive to use in heatsinks. Aluminum is the most common material used in heatsinks.
Is copper heatsink better than aluminum?
The copper heatsink is better than aluminum because of its lower thermal conductivity. The thermal conductivity for copper is about 250 W/mK, whereas it’s about 400 W/mK for aluminum. This means that the copper heatsink will be better at removing heat from a CPU because it has a lower thermal conductivity.
Is copper a good heatsink?
Copper is a good heatsink because it can conduct heat better than other metals. It has a high thermal conductivity which means it can quickly dissipate heat. Copper has also been shown to have reliable thermal properties for use in metal 3D printing, which is rapidly expanding into new industries.
Does copper retain heat better than stainless steel?
Copper is a better conductor of heat than stainless steel because it has a higher specific heat capacity, which means that it can absorb more energy before changing temperature. Copper also has a higher thermal conductivity, which means that it can transfer more heat to other surfaces faster.
