Custom Your Extruded Heat Sinks

Heat sink have many different produce processes, extruded heat sinks are the most common & cost-effective heatsinks used for thermal management in the industry. The most common aluminum alloys are 6063-T5, K=201 W/mK,  and 6063-T5, K=167 W/mK. These materials have excellent thermal conductivity.

Extruded heatsinks are usually supplied with a “finish” such as anodizing which can enhance its thermal performance. The heat sinks can also be supplied with a chromate finish which provides some corrosion protection.

Each extruded shape is unique to the requirements that it was designed for, extruded heat sinks are the most cost-effective cooling solution. Each heatsink is designed to achieve optimal thermal and structural performance.

The heat sink extrusion process allows to make innumerable shapes, here are some examples of extrusion heat sinks

How to custom extruded heat sink ?

The customization of extruded heat sinks usually involves the following steps:


First, it is necessary to determine the length, width, thickness, and shape of the heat sinks, such as square, rectangular, or circular, based on actual usage needs and industrial equipment specifications.


Secondly, select materials that match actual needs and aluminum alloy materials. Due to the good thermal conductivity of aluminum, the selection of aluminum alloy materials for aluminum extruded heat sinks is more lightweight and meets performance requirements.


Next, it is necessary to design the structure and arrangement of the heat sink according to the design requirements of the heat sink, including the spacing, number, and density of the heat sink. This step is very important when making a heat sink, as it affects the heat dissipation performance and stability of the heat sink. It is necessary to select the appropriate fin spacing, number of fins, and so on based on actual use needs.

After designing the size, material, structure, and other aspects of the heat sink, it is necessary to select appropriate aluminum extrusion production processes, such as aluminum extrusion, aluminum molding, casting, and so on. When making a heat sink, it is important to pay attention to the matching of material selection and production process to ensure that the heat sink meets quality and performance requirements.

After determining the design of the heat sink and the aluminum extrusion production process, sample testing and batch production are required. After testing and inspecting the performance and quality of the heat sink, ensure that it meets the requirements before batch production. At the same time, it is also necessary to conduct quality testing on the heat sink to ensure that the quality of the heat sink can meet the standard requirements.


Finally, the heat sink was packaged and shipped according to customer requirements, and the customized service for aluminum extruded heat sinks was completed.

In summary, customization of extruded heat sinks is a very important service, which requires selecting appropriate aluminum extrusion production processes and aluminum alloy materials based on specific needs to ensure that the quality and performance of heat sinks meet requirements.

Extruded Heat Sink Profiles

Extruded heat sink profiles are available in various designs to meet the diverse cooling requirements of electronic devices. Some of the common extruded heat sink profiles include the following:

1. Straight Fin Heat Sinks: These types of heat sinks feature straight, uniform fins that run parallel to the extrusion direction. They offer high thermal performance and are suitable for applications with low to medium airflow.

2. Pin Fin Heat Sinks: These heat sinks are designed with several small pins instead of straight fins. The pins increase the surface area of the heat sink, resulting in efficient heat dissipation even in low airflows.

3. Elliptical Fin Heat Sinks: As the name suggests, these heat sinks have fins with an elliptical cross-section. This design maximizes the surface area of the heat sink, resulting in better cooling performance.

4. Radial Fin Heat Sinks: Radial fin heat sinks feature fins arranged in a circular pattern. This design round heat sink extrusion provides better airflow through the heat sink, making it suitable for high-performance applications.

5. Customized heat sink profiles: Customized extruded heat sink profiles are designed to meet the specific cooling requirements of complex electronic devices. They can be designed with different fin densities, shapes, and sizes to optimize heat transfer in high-performance applications.

Extruded heat sink profiles are cost-effective, easy to manufacture, and offer superior thermal performance, making them an ideal solution for cooling electronic devices.

The Advantages Of Aluminium Extruded Heat Sink

extruded heat sink - Famos 3

While the main function of a heat sink is to regulate temperature and prevent any heating issues, it also aids in preventing breakage and even provides heat in case the temperature is too low. Copper and aluminum are the two primary metals used in creating heat sinks

Here are some of the benefits of Aluminium extruded heat sinks

1.  Aluminum is a great thermal conductor, which is the main factor while creating heat sinks. In addition to this, it is popular for heat dissipation, high-strength metal heating, and lightweight material. The metal can be squeezed into various shapes of radiation, whether its wide flat heat sinks or oval sinks.

2.  The Corrosion-resistant and rust-free material of aluminum is another reason why aluminum extrusion heatsinks are widely used across industries as it serves along without causing any heating issues

3.  High-pressure bearing and strength are among the qualities of aluminum extruded products. Even in the case of thinness or thickness, aluminum can handle sufficient pressure without getting damaged.

4. Aluminum is capable to handle various surface treatments with a wide range of designs and colors, making the final product look durable and attractive to be used for different devices.

Extruded Heat Sink FAQ

Extruded Heat Sink Material

Extruded heat sinks are the most common heat sink used for thermal management today. They are manufactured by pushing hot aluminum billets through a steel die to produce the final shape. The most common aluminum alloy is 6063-T5, but other 6XXX alloys can also be examined as needed.

How To Cut Extruded Aluminum Heat Sink?

Most extruded aluminum heat sinks manufacturers use fully automatic aluminum cutting machines, which are relatively mature solutions. Due to the high precision of the automatic aluminum cutting machine, some equipments reach 0.01 mm. This effectively ensures the accuracy of the sawing, and for those extruded aluminum heat sinks with low sawing difficulty, the high precision of the spindle makes it possible to use ultra-thin saw blades.

Extruded Heat Sink Cost

That being said the lowest tooling costs for a small extruded heatsink will be in the range of 500-1000 $. Per unit cost will conversely be in the range of a few dollars.

Extruded Aluminum Heat Sink Material Choice

Most extruded heat sinks are made from aluminum alloys, mainly from the 6000 alloy series, where aluminum dominates. Trace amounts of other elements are added, including magnesium and silicon. These alloys are easy to extrude and machine, are weldable, and can be hardened.
