Introduction

Aluminum extrusion heat sinks offer a cost-effective and highly efficient solution for cooling heat-generating electronic components. While standard extrusions handle basic cooling, our high-end custom extrusion designs are engineered for the most thermally challenging applications—including PCs, telecommunications infrastructure, industrial equipment, and high-power LED lighting.
To maximize design flexibility, our aluminum extrusion heat sinks can be further customized with embedded heat pipes, captive mounting hardware, and color anodizing—giving you a complete thermal solution, not just a component.

Our Value Proposition

Why choose our extrusion heat sinks for your critical applications？

Unmatched Thermal Efficiency
Achieve a fin height-to-pitch ratio of over 20:1, enabling significantly higher surface area density. This means you get superior heat dissipation in a compact footprint, perfect for high-density electronic enclosures.
Ultra-Wide Capabilities (No Size Limits)
Unlike standard extrusions limited by die size, our advanced friction stir welding (FSW) process allows us to create heat sinks with virtually unlimited widths. This eliminates design constraints and enables cooling for large-format power systems and industrial drives.
End-to-End Customization
From material selection (AL6063-T5/T6) to surface finishing (anodizing, nickel plating, chromating) and mechanical assembly (heat pipes, mounting hardware), we provide a single-source solution. You get a ready-to-install part, reducing your supply chain complexity.
Proven Material Performance
Using premium AL6063 alloy, our heat sinks offer excellent thermal conductivity (approx. 200 W/m·K), good corrosion resistance, and optimal extrudability—ensuring both performance and durability in demanding environments.
Cost-Effective for Medium to High Volumes
Extrusion is inherently economical for production runs. By optimizing the die design and post-processing, we deliver the lowest possible cost per performance ratio without sacrificing quality.
