Benefits Of Using 6063/6061 Aluminum Profile Heat Sink Extrusion
The aluminum alloys 6063 and 6061 are the most widely used alloys for making heat sinks because of the benefits they offer. Most types of aluminum are either too soft or they can’t handle the extrusion process. On the other hand 6063 and 6061 aluminum alloys have properties that make it ideal for manufacturing heat sinks. Below are some of the major benefits of using aluminum alloys for making heat sinks:
High thermal conductivity:
The 6063 aluminum alloy has a thermal conductivity rating of 201, while 6061 grade aluminum has a thermal conductivity of 166.
The high thermal conductivity of these aluminum alloys combined with other properties make them ideal for making heat sinks.

Lightweight:
Another reason why these aluminum alloys are so popular for making heat sinks, because of being light weight. They don’t add too much weight to the electronic device allowing you to maintain a lightweight product design.
More importantly despite being light weight the 6063 and 6061 aluminum are still highly durable.
Extrusion is easier for these aluminum alloys:
The aluminum alloys in question are softer than steel which means it is easier to make extrusions on them. Extrusions play a key role in maximizing heat dissipation.
If you have a specific extrusion design for your aluminum heat sink we can easily manufacture it using the 6063 and 6061 aluminum alloys.
High corrosion resistance:
Aluminum has an inherit property to form a protective layer of aluminum oxide on its surface. This additional surface prevents further corrosion of the heat sink and increases the service life.
The corrosion resistant nature of aluminum alloys is especially handy in the constant heating and cooling applications such as for making heat sinks. No matter how many times the heat sink is heated or cooled down it doesn’t develop oxidation thanks to aluminum’s corrosion resistant properties.

Design Considerations For 6063/6061 Aluminum Profile Heat Sink
When designing a custom heat sink it is essential to take various design factors into consideration. Here are some design considerations for the 6063 and 6061 aluminum alloy heat sinks, that you should know about:
Shape and dimensions of the heat sink fins: The fins on the aluminum heat sink play a key role in dissipating heat. When the air flows over the heat sink it cools the fins down which ultimately cools down the board below it. It is essential to make sure that the fins are configured in such a way on the heat sink that they don’t stop the flow of air.
Air should be able to flow with as little resistance as possible to ensure proper cooling effect. In addition to ensuring maximum air flow the heat sink fins should be able to move the maximum amount heat from the source of heat towards the top of the heat sink. Therefore the shapes of the fins should be carefully designed around maximum air flow and heat dissipation.
Heat sink attachment methods: The way you attach the heat sink to the circuit or board can play a key role in how well it dissipates heat. Some commonly used attachment methods for heat sinks include thermal tape, clips, and push pins.
The choice of attachment method depends on the size of the aluminum heat sink and the amount of heat being generated. No matter what attachment method you utilize it should be properly fitted to the circuit.
Surface finish: An often overlooked factor when designing aluminum heat sinks is choosing the right surface finish. You should pick the surface finish earlier on during the design process because it has a direct impact on a heat sink’s ability to dissipate heat.

How To Choose The Right Aluminum Extrusion?
There are some factors that should be taken into consideration to ensure the correct aluminum extrusion. Here are some of the key considerations for ensuring the right extrusion:
Extrusion temperature: The temperature used during the extrusion process effects the quality of the heat sink. The aluminum should only be heated to a point where it is melted and can be extruded easily. Excess temperatures can result in low quality heat sinks.
Speed of extrusion: If aluminum is extruded too rapidly it can reduce the accuracy of the end product. So it is essential to extrude the heat sink at the right speed to achieve the best results.
Cooling speed: Cooling of aluminum extrusion plays a key role in the durability of the heat sink. Therefore the cooling rate should be controlled using water or other cooling mediums to make sure the custom heat sink achieves the desired hardness.
Tips For Installing And Maintaining Your Aluminum Heat Sink
Aluminum heat sink installation tips:
Make sure that the surface you are installing a heat sink on is clean to ensure proper contact.
Use a thermal paste at the contact point of the electronic component and heat sink for maximum heat dissipation.
Make sure the heat sink is properly secured to the component and there are no gaps.
Aluminum heat sink maintenance tips:
Regularly remove dust and other unwanted particles from the heat sink to maintain its ability to dissipate heat.
Change the thermal paste regularly to make sure it hasn’t dried up.
Prevent physical stress to heat sinks as it can potentially damage the aluminum fins.
