Understanding Extruded Heat Sinks

Extruded heat sinks are manufactured through an aluminum extrusion process where heated aluminum billets are forced through a die to create specific cross-sectional profiles. This process enables consistent, repeatable production of heat sink designs with excellent dimensional accuracy.

The extrusion method offers outstanding cost-effectiveness for medium to high-volume production runs, making it the preferred choice for many thermal management applications across industries.

Extruded aluminum heat sinks combine lightweight construction with good thermal conductivity, providing reliable cooling performance for power electronics, LED systems, and industrial equipment.

Frequently Asked Questions

What is the difference between extruded and skived heat sinks?

Extruded heat sinks are formed by pushing heated aluminum through a die, creating consistent profiles suitable for cost-effective production. Skived heat sinks are machined from solid blocks with fins shaved from the base, offering better thermal performance but at higher cost. Extrusion is ideal for standard applications and high volumes.

Can extruded heat sinks be customized to specific dimensions?

Yes, we can create custom extrusion dies to produce heat sinks with your specific cross-sectional profile. Once the die is manufactured, we can extrude profiles to any required length and cut them to your exact dimensions. Custom tooling is cost-effective for medium to high production volumes.

What aluminum alloys do you use for extruded heat sinks?

We primarily use 6063-T5 and 6061-T6 aluminum alloys. 6063-T5 offers excellent extrudability and good thermal conductivity, making it ideal for most heat sink applications. 6061-T6 provides higher strength and is preferred for applications requiring enhanced mechanical properties. Both alloys provide excellent corrosion resistance.

What surface finishes are available for extruded heat sinks?

We offer multiple surface treatment options including natural aluminum finish, clear or colored anodizing (Type II and Type III), powder coating in various colors, and chemical film coating (chromate conversion). Anodizing is most popular as it enhances corrosion resistance while maintaining thermal performance and can improve heat radiation through increased emissivity.

What is the typical delivery time for custom extruded heat sinks?

For existing standard profiles, we can typically ship within 2-3 weeks depending on quantity and finishing requirements. Custom extrusion projects requiring new die tooling typically take 4-6 weeks for die production plus 2-3 weeks for extrusion and finishing. We work with reliable global logistics partners to ensure timely delivery worldwide.

Do you provide thermal performance testing for extruded heat sinks?

Yes, we can provide thermal performance testing and analysis. Our engineering team can conduct thermal simulation using CFD software during the design phase, and we can perform actual thermal testing on prototypes or production samples. We provide detailed test reports including thermal resistance measurements under specified conditions.
