The heat sink price list 2026 covers stamped 6063-T5 aluminium heat sinks produced on 160 T tooling at 120,000 pcs per run. Fins are formed at 0.4 mm gauge and 4.0 mm pitch with ±0.03 mm repeatability, giving 0.62 K/W at ΔT = 60 K. Standard black anodize Type II, 10-15 µm, protects fin roots after forming. Mounting face flatness is 0.05 mm over 100 mm, and unit weight starts from 15 g.

Running at 120,000 pcs, this heat sink price list 2026 is pressed on 160 T tooling with ±0.03 mm repeatability. 6063-T5 aluminium gives 0.62 K/W at ΔT = 60 K, and black anodize Type II, 10-15 µm is applied as standard.
Stamping gives a repeatable 0.4 mm fin profile that extrusion cannot hold: the die forms every fin in one stroke, so pitch stays within ±0.03 mm across a 120,000 pcs run.

Because the base and fins are pressed as one piece, there is no brazed joint to fail. 0.05 mm over 100 mm flatness on the mounting face is held directly from the tool, which keeps thermal interface contact uniform.
Low fin gauge is where stamping wins: 0.4 mm fins at 4.0 mm pitch give more surface per cubic millimetre than a machined or extruded profile of the same envelope.
Pressing 6063-T5 aluminium keeps the heat sink price list 2026 light, from 15 g depending on envelope, without sacrificing fin density, which matters where airflow path length is already fixed by the enclosure.
The black anodize Type II, 10-15 µm finish is applied after forming, so corrosion protection does not get cut through at the fin roots the way it does on machined alternatives.

The standard material is 6063-T5 aluminium, supplied with black anodize Type II, 10-15 µm. For applications where LED high bay lighting exposure is a concern, we recommend the passivated route; where conductivity matters more than weight, copper C110 raises thermal performance and roughly doubles unit mass.
General dimensions run to ±0.20 mm, with critical features such as ±0.05 mm on mounting hole position held separately. Formed geometry inherits tooling repeatability of ±0.03 mm, and hole position is held to ±0.15 mm. Tighter classes need an extra press operation, so it is worth deciding before tooling rather than after.

Flatness is checked on a granite surface plate, 20 °C against a 0.05 mm over 100 mm limit, and fin pitch is verified optically at ±0.03 mm. Reports go out with each lot.
Incoming 6063-T5 aluminium is checked for thickness and hardness before it enters the press. After forming, CMM plus 100% hydraulic press leak test confirms 0.05 mm over 100 mm and 4.0 mm against the drawing.
Flatness is measured on granite rather than on cast iron, because 0.05 mm over 100 mm at 200 x 100 x 80 mm reads differently on a plate that has not been lapped. Records keep both readings.
Final containment is PE bag + honeycomb carton, 15 kg per carton. Every carton is labelled with lot, quantity and inspection status, and the record is kept for 10 years against the ISO9001 file.
In LED high bay lighting, the 0.62 K/W rating determines how much airflow the enclosure still needs. At LED high bay lighting junction temperatures, 0.4 mm fins at 4.0 mm pitch keep the delta-T inside the sensor budget.

LED high bay lighting programs are the reason this geometry exists. Where the enclosure cannot grow taller, fin density is the only lever, and 4.0 mm pitch with 0.4 mm stock is the practical ceiling for aluminium.

Where a heat sink price list 2026 runs at LED high bay lighting volumes, part-to-part consistency decides field returns. ±0.03 mm on a 120,000 pcs run keeps the thermal curve inside one band.

LED high bay lighting packaging and vibration rules push toward one-piece construction. A stamped heat sink price list 2026 has no adhesive to creep, which is the usual failure mode in two-part coolers.

Prototype is 5 working days from drawing approval; production is 15 working days after the first article is signed off. Tooling for a new part takes . We quote EXW, and sea freight to Europe runs about 25 to 30 days after booking.
6063-T5 aluminium is the standard choice. For LED high bay lighting in a corrosive environment we specify 6063-T5 with black anodize Type II, 10-15 µm; for the highest conductivity we move to copper C110, which raises cost and weight but drops thermal resistance by roughly half at the same envelope.

The family covers 200 x 100 x 80 mm, with unit weights from 15 g. Because the base is pressed, new sizes are a die insert change rather than a new press line, so development is usually 2 weeks rather than 8.

The key is avoiding a second metal at the wet contact area. We recommend black anodize Type II, 10-15 µm and, where the part touches an aluminium chassis, an isolating washer. Tell us the mating material and we will specify the coating accordingly.
Skived fins are milled, so you get thin, tall fins and higher density in a given height, but the cost scales directly with fin area. Stamping gives the same result in one stroke at a much lower unit cost below 120,000 pcs. For LED high bay lighting in a fixed-height enclosure, stamped is normally the right answer.
Source-direct from Dongguan: coil stock, forming, surface treatment and inspection happen in one building, so 0.05 mm over 100 mm flatness is verified before the part is packed.
Our LED high bay lighting experience runs back to the first tooling programme in 2015. That history is why the standard black anodize Type II, 10-15 µm and ±0.20 mm are conservative rather than optimistic.
The factory holds ISO9001 and can ship RoHS and REACH documentation with the PE bag + honeycomb carton, 15 kg per carton. Third-party SGS inspection is arranged on request before the container is sealed.

Pricing is based on stamped 6063-T5 aluminium heat sinks run at 120,000 pcs on 160 T tooling. Fins are 0.4 mm at 4.0 mm pitch with ±0.03 mm repeatability, 0.62 K/W at ΔT = 60 K, and standard black anodize Type II, 10-15 µm.
Standard material is 6063-T5 aluminium. Standard finish is black anodize Type II, 10-15 µm, applied after forming so corrosion protection is not cut through at the fin roots. Unit weight starts from 15 g depending on envelope.
The die forms 0.4 mm fins at 4.0 mm pitch in one stroke, holding pitch within ±0.03 mm across a 120,000 pcs run. This gives more surface per cubic millimetre than a machined or extruded profile of the same envelope.
The mounting face holds 0.05 mm over 100 mm flatness directly from the tool. This keeps thermal interface contact uniform. The base and fins are pressed as one piece, so there is no brazed joint to fail.
The stamped 6063-T5 aluminium design gives 0.62 K/W at ΔT = 60 K. Performance depends on airflow path length fixed by the enclosure, but the 0.4 mm fins at 4.0 mm pitch maintain fin density within the same envelope.
Production runs at 120,000 pcs on 160 T tooling with ±0.03 mm repeatability. The die forms every fin in one stroke, so pitch stays within ±0.03 mm across the run. Inspection is performed before every shipment.
Stamping holds a 0.4 mm fin profile at 4.0 mm pitch that extrusion cannot maintain, with ±0.03 mm repeatability. The one-piece base and fins eliminate brazed joints. Black anodize Type II, 10-15 µm, protects fin roots better than machined alternatives.
