Extruded Aluminum Heat Sinks

High-Quality Extruded Aluminum Heat Sinks - Always Delivered On Time

Aluminum extrusion is the most common process for manufacturing heat sinks. This process is cost-effective, and custom specifications can easily be manufactured. Producing heat sinks from aluminum allows for significant weight savings over copper.

Custom Extruded Heat Sink Fabrication

If you already have a design for your heat sink extrusions, we can help you manufacture them. Our partner facilities in India offer a wide range of capabilities to get you the alloy, surface finish, and secondary operations you need.

The Minimum Order Quantity (MOQ) for heat sink extrusions is 1000 kg (1.1 US tons). Producing in India allows for significant cost savings over domestic producers while still maintaining good quality.

Alloy Selection

Aluminum alloys in the 6000 series offer good thermal conductivity, are widely available, and are fairly strong. They tend to extrude well, too. The most common alloys for extruded heat sinks are 6061 and 6063. Our partner extrusion facilities can extrude in these alloys or in the alloy of your choice. On-site foundries give customers with medium to high volume orders a wide range of options. Let us know the alloy and temper you prefer.

Surface Finishing

We offer a range of finishing options. One of the most common surface finishes for heat sinks is anodization. This electrochemical process increases surface emissivity, corrosion resistance, wear resistance, and electrical isolation. Coatings like paint or powder are not recommended because they will act as insulators. Heat sinks can be anodized at our extrusion facilities with colored dyes. Let us know about your preferences.

Post Machining & Secondary

One way to help maximize the surface area of extruded heat sinks is by cross-milling after extrusion. CNC machining is a very precise way to convert the fins on extruded heat sinks into pins. Pins help to maximize heat dissipation, making your heat sink more effective. In addition, we can perform other secondary operations like drilling, stamping, and cutting. Tell us about any secondary operations your project may require. Reach out to us.
