Skived Fin Heat Sink
- Monolithic one-piece construction: Skived fin heat sinks are machined from a single block of aluminum (or copper), ensuring no joints between fins and base for superior thermal conductivity.
- Ultra-high fin density: Fins can be as thin as 0.2 mm, with minimal spacing-delivering significantly greater surface area and heat dissipation than traditional extruded designs.
- Highly efficient cooling: The integrated base-to-fin structure minimizes thermal resistance, enabling rapid heat transfer and enhanced cooling performance.
- Design flexibility without tooling cost: Skived manufacturing avoids expensive dies; fin height, thickness, and spacing are easily customized-ideal for prototyping and low-volume customization.
- Material versatility: Available in both aluminum and copper substrates-aluminum offers lightweight, cost-effective cooling; copper delivers superior thermal conductivity for high-power applications.
- Compact and lightweight: The thin fin profile enables compact designs with minimal added weight, suited to space-constrained or mobile electronic equipment.
- Robust mechanical integrity: With no fin-to-base interface, structural strength is enhanced, improving durability under thermal cycling or vibration.

Skived Fin Heat Sink-FAQ's
What is a skived fin heat sink?
Our skived fin heat sinks are manufactured from a single solid metal block-either aluminum or copper-with fins shaved and bent up, forming a seamless base-to-fin structure.
How do skived fins improve thermal performance?
The thin, densely packed fins increase surface area dramatically, while the one-piece structure minimizes thermal resistance between fins and base.
Can fin dimensions be customized?
Yes-fin thickness, height, and spacing are all adjustable to suit specific thermal and airflow requirements.
What materials are used?
We offer options in aluminum for lightweight and cost-effective cooling, and copper for high-heat flux applications requiring superior conductivity.
Are skived heat sinks suitable for compact designs?
Definitely-the slim fin profile and high density allow effective cooling in tight form factors.
How does skiving compare to extrusion?
Unlike extrusion, skiving does not require expensive tooling and enables finer, thinner fins for superior heat dissipation in customized designs.
Which industries benefit most?
Ideal for high-performance electronics, power modules, LEDs, telecom, inverters, EV power electronics, and compact industrial devices.
Do you offer surface finishing?
Yes-anodizing, black-oxide, or other protective coatings are available to enhance corrosion resistance and fit design requirements.
Can mounting features be added?
Yes-mounting holes, threads, and mechanical interfaces can be machined directly as part of the customization process.
Is this suitable for prototyping?
Absolutely-skived fin heat sinks are cost-effective for prototyping, as the lack of dedicated tooling allows rapid design iteration.
