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.

What is the Melting Point of Aluminum, and Why is it Significant?

When evaluating aluminum for a product application, designers are typically most interested in properties like it’s high strength-to-weight ratio, its corrosion resistance, or even its value as a heat sink. This means aluminum’s melting point can easily be overlooked....

What is Alodine Finish, and How Does it Compare to Anodizing?

Aluminum is naturally corrosion-resistant, but when that’s not enough, designers will need to choose a protective aluminum surface finish. Alodining is a popular finishing option for preventing corrosion while still allowing electrical conductivity through the...
