Running at 300,000 pcs, this aluminum heat sink price list 2026 is pressed on 25 T tooling with ±0.05 mm repeatability. pure copper C110 gives 0.62 K/W at ΔT = 60 K, and clear anodize Type II, 5-10 µm is applied as standard.
Design Approach and Process
Stamping gives a repeatable 0.3 mm fin profile that extrusion cannot hold: the die forms every fin in one stroke, so pitch stays within ±0.05 mm across a 300,000 pcs run.
Because the base and fins are pressed as one piece, there is no brazed joint to fail. 0.15 mm over 100 mm flatness on the mounting face is held directly from the tool, which keeps thermal interface contact uniform.
A single 25 T stroke forms the whole aluminum heat sink price list 2026, so part cost stops scaling with complexity. Tooling runs ±0.05 mm, and the 25 s cycle feeds a 300,000 pcs line.
The one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path. Nothing sits between pure copper C110 and the airflow except the stamped surface itself.
Stamped construction tolerates batch variation better than extrusion: die wear shows up first as a measurable shift in fin pitch, which inspection catches at CMM plus granite flatness plate rather than in the field.
Material Selection and Surface Finish
The standard material is pure copper C110, supplied with clear anodize Type II, 5-10 µm. For applications where telecom and base station 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.
Tolerance Classes You Can Specify
General dimensions run to ±0.10 mm, with critical features such as ±0.05 mm on base thickness held separately. Formed geometry inherits tooling repeatability of ±0.05 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.
Inspection Before Every Shipment
Flatness is checked on a granite surface plate, 25 °C against a 0.15 mm over 100 mm limit, and fin pitch is verified optically at ±0.05 mm. Reports go out with each lot.
Each batch carries a CMM report from CMM plus granite flatness plate. We record flatness, pitch, base thickness and hole position, and flag anything outside ±0.10 mm before it leaves the line.
Incoming pure copper C110 is checked for thickness and hardness before it enters the press. After forming, CMM plus granite flatness plate confirms 0.15 mm over 100 mm and 1.5 mm against the drawing.
Sampling is AQL 0.65 for critical dimensions and 1.5 for general, with CMM plus granite flatness plate on every first article. Deviations beyond ±0.10 mm trigger a full-lot sort.
Where This Part Is Used
In telecom and base station, the base usually doubles as the mounting interface. 1.5 mm with 0.15 mm over 100 mm flat gives a stable surface for the telecom and base station thermal pad.
Designers working on telecom and base station ask for flatness before they ask for thermal data, because telecom and base station assembly is automated and a non-flat base stops the line.
telecom and base station designs often run a 2.0 m/s forced-air path. 0.62 K/W at ΔT = 75 K, forced air 2.0 m/s means telecom and base station can hold its target with fan power below the acoustic limit.
For telecom and base station prototypes, 5 working days covers drawing review and first article. Production lots move to 10 working days once the ±0.05 mm capability is signed off.

FAQ: Your Questions Before Ordering
Which materials do you recommend?
pure copper C110 is the standard choice. For telecom and base station in a corrosive environment we specify 6063-T5 with clear anodize Type II, 5-10 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.
Do you test for thermal resistance?
We test at ΔT = 75 K, forced air 2.0 m/s and report 0.62 K/W. That is a steady-state figure, not a transient: for telecom and base station first-power-on behaviour you need a different test, and we can run it on request.
Do you make the aluminum heat sink price list 2026 in different sizes?
The family covers 20 x 20 x 10 mm, with unit weights from 650 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.
Is there any risk of the fins bending in transit?
With 0.3 mm fins and standard PE bag + honeycomb carton, 15 kg per carton, damage is rare. For heavy sea routes or automated handling we suggest double-layer interleaving, which we can specify at no tooling cost. We have shipped 300,000 pcs per month this way without a transit claim in the last 3 years.
Do you provide CAD files or a drawing?
We supply a 2D drawing with the CMM report, and 3D STEP on request. Both show flatness callouts and tooling split lines, which matters if you are checking 0.15 mm over 100 mm in your own assembly.
How We Manufacture and Ship
The line sits in Dongguan in a single ISO9001 plant. 25 T presses cover the aluminum heat sink price list 2026 family, and 300,000 pcs per month is current committed output.
Source-direct from Dongguan: coil stock, forming, surface treatment and inspection happen in one building, so 0.15 mm over 100 mm flatness is verified before the part is packed.
Quality staff sit beside the press, not in a separate room. Deviations on 1.5 mm or 0.15 mm over 100 mm stop the run at the tool rather than at final inspection.

Frequently Asked Questions
What is the price list for aluminum heat sink 2026 based on?
The 2026 price list is based on a 300,000 pcs run on 25 T tooling with ±0.05 mm repeatability and a 25 s cycle. Pure copper C110 gives 0.62 K/W at ΔT = 60 K, and clear anodize Type II, 5-10 µm is standard. One-piece stamping removes brazed joints and adhesive layers.
What material and surface finish are standard?
Pure copper C110 is used for 0.62 K/W at ΔT = 60 K. Clear anodize Type II, 5-10 µm is applied as standard. The one-piece stamped construction removes the adhesive layer found in two-part coolers, cutting the thermal path between copper and airflow.
What tolerance and flatness can you hold?
Tooling runs ±0.05 mm, and the die forms every fin in one stroke so pitch stays within ±0.05 mm across a 300,000 pcs run. Flatness is 0.15 mm over 100 mm on the mounting face, held directly from the tool for uniform thermal interface contact.
Why choose stamping over extrusion for this heat sink?
Stamping gives a repeatable 0.3 mm fin profile that extrusion cannot hold. The die forms every fin in one stroke, so pitch stays within ±0.05 mm across a 300,000 pcs run. Stamped construction also tolerates batch variation better because die wear shows up as a measurable fin pitch shift.
A single 25 T stroke forms the whole part, and the 25 s cycle feeds a 300,000 pcs line. Because base and fins are pressed as one piece, part cost stops scaling with complexity. Tooling runs ±0.05 mm for the full run.
How do you inspect fin pitch and flatness before shipment?
Inspection uses CMM plus granite flatness. Die wear shows up first as a measurable shift in fin pitch, which inspection catches. Flatness is 0.15 mm over 100 mm on the mounting face. Tooling holds ±0.05 mm, and the 0.3 mm fin profile is checked across the 300,000 pcs run.
Does the one-piece design improve thermal performance?
Yes. Because base and fins are pressed as one piece, there is no brazed joint to fail. The one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path. Nothing sits between pure copper C110 and the airflow except the stamped surface itself, supporting 0.62 K/W at ΔT = 60 K.
