Large Aluminum Heat Sink-FAQ's
What qualifies as a “large” heat sink?
Profiles with widths well beyond typical PCB-scale sinks-often exceeding 100 mm-designed for high-power thermal management.
What alloys are used?
We typically use 6063-T5 for its compatibility with extrusion and thermal performance; 6061 or 6082 are available for enhanced strength.
Can you customize fin design?
Yes-we adapt fin geometry (straight, high-aspect, pin-fin) to match airflow and space constraints.
What surface finishes can be applied?
Options include anodizing, powder coating, or raw finish depending on function and aesthetics.
Are prototypes available?
Yes-we offer prototype extrusions for testing before proceeding with mass production.
What industries use large extruded heat sinks?
Common in LED luminaires, telecom base stations, industrial power modules, and EV applications.
How do we ensure consistency?
Extrusion tooling and process control ensure uniform profile quality across batches.
Is extruded heat sink a lightweight choice?
Yes-aluminum balances effective cooling with a lightweight structure, enhancing manufacturability and installation.
