Comparison between Aluminium Extrusion and Traditional Heat Sinks

In order to dissipate heat produced by the components, heat sinks are a crucial component in many electronic devices, including computers, smartphones, and LED lights. Traditional heat sinks have been in use for a long time and are typically made of sheets of copper or aluminium. The rise of aluminium extrusion heat sinks, which have several advantages over traditional heat sinks, is a result of recent technological advancements. The advantages of extruded heat sinks will be highlighted in this article as we contrast them with traditional heat sinks and compare and contrast heatsink extrusionssss with them.

What is an Aluminum Extrusion Heat Sink?

Aluminium alloy is forced through a die to create a long, uniformly shaped piece that is an aluminium extrusion heat sink. Heat sinks with intricate designs and shapes, such as fins and channels that improve thermal performance, can be produced using this method. Additionally, extrusion can be used to make heat sinks that are inexpensive, lightweight, and have excellent thermal conductivity.

Advantages of Aluminum Extrusion Heat Sinks over Traditional Heat Sinks

Thermal Performance

The superior thermal performance of aluminium extrusion heat sinks one of their most important benefits. Extruded heat sinks have fins and channels that have a large surface area for heat dissipation, allowing for the effective cooling of electronic components. Smaller heat sinks can be used due to the increased surface area, which can free up space in electronic devices.

Traditional copper or aluminium heat sinks, in contrast, frequently have a smaller surface area, which restricts their capacity to efficiently dissipate heat. As a result, bulkier and more expensive designs are frequently required in order to achieve the same level of thermal performance as an extruded heat sink.


The lightweight design of aluminium extrusion heat sinks another benefit. Heat sinks with thin walls, and intricate shapes can be produced using the extrusion process, which is not possible with traditional manufacturing techniques. Particularly for portable electronic devices like smartphones and laptops, where every gram counts, this lightweight design is crucial.

Traditional heat sinks, on the other hand, are typically heavier due to their thicker construction and are made of copper or aluminium sheets. For portable devices, the weight of the heat sink can have a significant negative impact on the device’s overall portability and usability.


In comparison to traditional heat sinks made from copper sheets, aluminium extrusion heat sinks are also more affordable. Extrusion reduces the need for additional machining and assembly steps by enabling the production of heat sinks with intricate shapes and patterns. As a result, extruded heat sinks are more affordable to produce than traditional heat sinks, making them a desirable choice for manufacturers on a budget.

Traditional copper heat sinks, in contrast, need more machining and assembly steps, which raises the cost of production. Traditional heat sinks are built thicker, which means that more material is needed, raising the overall cost.

Design Flexibility

The design flexibility of aluminium extrusion heat sinks is greater than that of traditional copper or aluminium sheets-based heat sinks. Heat sinks with intricate designs and shapes, including fins, channels, and other elements that improve thermal performance can be produced through the extrusion process. This design flexibility enables the development of specialized heat sinks that are catered to particular applications, leading to better performance and increased efficiency.

As a result of the limitations of the manufacturing process, traditional heat sinks made from copper or aluminium sheets offer less design flexibility. As a result, heat sinks may not be designed with particular applications in mind, which could result in reduced thermal performance and efficiency.


The advantages of an aluminium extrusion heat sink over traditional copper or aluminium sheets-based heat sinks are numerous. Extruded heat sinks are a desirable option for producers of electronic devices due to their superior benefits. Traditional heat sinks will still be used in many applications, but aluminium extrusion heat sinks have advantages that cannot be overlooked. The extrusion method has transformed the production of heat sinks and created new opportunities for the functionality and design of these crucial parts.
