Material Selection: Aluminum vs. Copper Heat Sink Extrusions

The choice between heat sink aluminum extrusion and extruded copper heat sink involves trade-offs between thermal performance, weight, and cost:

Aluminum Heat Sink Extrusion: Best balance of thermal performance (160-220 W/m·K), lightweight, and cost-effectiveness; ideal for most LED, electronics, and industrial applications

Extruded Copper Heat Sink: Superior thermal conductivity (380-400 W/m·K) for extreme heat flux applications; higher density and cost but unmatched performance in compact spaces

Hybrid Solutions: Aluminum body with copper heat pipes or inserts for targeted high-heat areas

Frequently Asked Questions (FAQ)

Q: What is the minimum order quantity for custom extruded heat sinks?

A: MOQ depends on profile complexity and tooling investment. For new custom dies, typical MOQ is 500-1000 meters. For existing dies or standard profiles, MOQ can be as low as 100 meters.

A: We routinely produce fins as thin as 0.8mm for aluminum extrusions. The practical limit depends on fin height (aspect ratio) and alloy selection.

A: Clear anodizing is most common for optimal thermal performance. Black anodizing provides better radiation heat transfer. For electrical insulation or specific colors, powder coating is recommended.

A: Yes, multi-cavity extrusions are possible for complex designs. This allows integration of mounting features, wire channels, or additional functional elements.

A: Yes, we offer complete thermal solutions including fan attachment, heat pipe integration, and thermal interface material application.

A: We prefer 2D DXF/DWG files of the cross-section profile. 3D STEP or IGES files are also acceptable. Our engineers can work from thermal requirements to develop optimal profiles.

A: For natural convection, we maximize fin spacing and surface area. For forced airflow, we optimize fin density and turbulence generation. Our thermal simulations model both scenarios.
