Skived fin heatsinks
Skived fin heatsinks are cut from a solid aluminum bar in one continuous shaving, producing extremely thin, tall, densely packed fins — maximum surface area where space is tight and power density is high.
When to choose skived
A skived fin heatsink delivers far higher fin density than extrusion — fins can be < 0.3 mm thick and very tall — so it suits high-power semiconductors in compact enclosures (IGBT, power modules, RF). There is no die, so prototyping is fast and economical at low volume.
The fins are integral with the base (no bond line), giving excellent conduction from fin to base.
Typical specs
- Fin thickness: 0.2–0.5 mm
- Fin height: up to ~100 mm
- Alloy: 1060 / 6063 / 6061
- Finish: anodized
Capability

| Finish | Anodize II/III |
Design tip
- Skived fins are delicate — plan handling and packaging (fin-safe).
- Pair with a flat, machined base for best contact.
