One Aluminum Profile. A Continuous Thermal Path
An extruded heat sink forms the base and fins from one aluminum profile. A consistent cross-section supports efficient repeat production, while machining adds the interfaces your assembly needs.
Integral base and fins
The continuous metal structure carries heat from the mounting face into the fin field without a bonded fin joint.
Length tailored to your enclosure
Cut the profile to the required length, then machine mounting holes, threads and contact surfaces.
Designed around the operating conditions
Fin geometry, heat-source footprint and installed airflow are reviewed together to control temperature rise.
Turn your installation constraints into a practical profile.
Review My Requirements
Built to Simplify Thermal Design and Repeat Purchasing
Keep the thermal path, mechanical fit and purchasing plan aligned with a profile that is practical to manufacture and easy to inspect.
A direct thermal path
Integral fins eliminate a separate fin-to-base bonding operation, reducing process variables in the heat-spreading structure.
Less assembly rework
Controlled contact faces, hole positions and threads help the approved part fit the first time.
Predictable repeat orders
Material batches, drawing revisions and packaging identifiers stay linked from sample approval to replenishment.
Cost shaped by the design
Existing-profile review, machining access and quantity-based pricing expose practical ways to reduce total part cost.
Find the strongest combination of cooling, fit and unit cost.

Integral Extrusion Profile
EN-AW 6063 / 6061
| Profile Dimension | Standard Manufacturing Range |
|---|---|
| Cross-section width | 20–300 mm |
| Overall height | 10–100 mm |
| Cut length | 30–800 mm |
| Base thickness | 3–20 mm |
| Fin thickness | 1–3 mm |

Send the complete geometry so fin height, thickness, spacing and base strength can be assessed as one profile.
Check the feasibility of your cross-section before committing to tooling.
Check My ProfileChoose the Alloy for the Whole Mechanical Job
Thermal conductivity matters alongside strength, machining requirements and surface finish. We review the alloy and temper against your approved specification.
6063-T5 / T6
Extrusion OptimalA practical choice for extruded fin profiles and anodized appearance. Reference room-temperature conductivity: approximately 200 W/(m·K), depending on temper and temperature.
Thermal Conductivity Benchmark
~200 W/(m·K)
6061-T6
Mechanical & CNCSelected where the mechanical specification and machining requirements favor 6061. Reference room-temperature conductivity: approximately 167 W/(m·K), depending on material condition and temperature.
Thermal Conductivity Benchmark
~167 W/(m·K)
The purchase specification fixes the alloy, temper, finish and final inspection condition to keep repeat orders consistent.
Balance conductivity, strength and manufacturing requirements.
Confirm My MaterialFin Geometry Works Only When the Air Can Reach It
A denser fin field is useful only when the installation can move air through it. We evaluate spacing, orientation and bypass paths against the actual enclosure.
Natural convection
Allow an open inlet and outlet, use an installation orientation that supports buoyancy, and preserve practical clear spacing between fins.
Vertical Fin Orientation
Passive Cooling Arrangement
Forced airflow
Use measured airflow through the heat sink, check the fan operating point and pressure drop, and limit bypass around the fin field.
Longitudinal Fin Flow
Fitted Airflow Shroud
Share the inlet temperature, heat-source size, allowed temperature rise and airflow boundary with your drawing.
Design for the airflow inside your equipment.
Review My AirflowMachine the Interfaces That Make Assembly Repeatable
An extrusion becomes an assembly-ready component through controlled machining of the contact face, hole pattern and mounting details.
Contact faces
Typical machined flatness ≤0.05 mm across 100 mm; define the functional datum on the drawing.
Critical dimensions
Selected local dimensions within 100 mm can target ±0.02–0.05 mm after a machining review.
Mounting details
Add drilled and tapped holes, counterbores, slots and clearance features to match the device and fasteners.
Interface texture
Finish thermal contact areas to Ra 0.8–1.6 μm where specified and achievable for the geometry.
Make contact quality and mounting fit part of the same review.
Review My Drawing
Specify the Finish Without Losing the Functional Surfaces
Surface treatment is defined around corrosion exposure, appearance, electrical contact and the thermal interface so the finished part remains assembly-ready.
Anodized appearance
Natural, black or specified-color anodizing creates a controlled visual finish. Standard anodic film is typically 10–20 μm.
Masked working surfaces
Define thermal contact faces, grounding points and threads that must remain bare or receive a specified alternative treatment.
Final-state inspection
Inspect dimensions and coating requirements after processing so the fit reflects the part that enters your assembly.
Black anodizing is a finish choice; thermal performance still depends on the complete heat-transfer path and operating conditions.
Resolve coating, contact and grounding requirements before production.
Define My Finish
Cooling Built Into Industrial Equipment
Extruded profiles suit repeatable air-cooled assemblies where the heat load, installation space and manufacturing economics can be defined together.
Drives and inverters
Align the contact plane, mounting pattern and air path with the power stage to reduce assembly uncertainty.
Industrial LED systems
Combine a repeatable aluminum profile with the required mounting face and orientation for controlled heat removal.

A useful thermal number identifies the heat source, inlet temperature and measured airflow. That makes the result relevant to your design review.

Build your inspection requirements into the manufacturing plan.
Plan My Quality DocumentsA Clear Route From Drawing to Repeat Supply
Engineering, quality and purchasing move through the same controlled milestones so the sample you approve defines the production part.
Phase 01
01 · Define and review
Share 2D/3D files, heat load, air boundary and forecast volume. Review profile feasibility, interfaces and the quote scope.
Phase 02
02 · Freeze and sample
Confirm the drawing, material and finish. Routine drawing-led samples typically take 10–20 working days after the drawing is frozen.
Phase 03
03 · Validate and approve
Check first-article dimensions and test the assembly under the agreed operating conditions before production release.
Phase 04
04 · Manufacture and replenish
Schedule repeat orders against the approved revision and packaging plan. Mature parts with existing tooling typically run in 15–30 calendar days once release conditions are met.
Give your project a practical path to production approval.

Resolve the Questions Before You Send an RFQ
Prepare the technical and purchasing details that help us return a useful feasibility review and a clearly scoped quotation.
What should I send with an inquiry?
Send a PDF drawing and STEP model if available, along with heat load, heat-source size, inlet temperature, airflow conditions, mounting space and annual volume.
Can you use an existing extrusion profile?
We first review the available cross-section against your thermal and mechanical boundaries. A new die is considered when the required geometry cannot be met by an existing profile.
What are the typical sample and production quantities?
Paid engineering samples can start from one piece. Routine extruded production orders typically begin at 50–100 pieces, depending on geometry, existing tooling and process scope.
Which documents can accompany the parts?
The agreed package can include material batch evidence, a certificate of conformity, first-article and dimensional reports, finish requirements and part-linked compliance information.
Can black anodizing replace an airflow review?
No. Finish, radiation and convection are evaluated with the contact interface and operating conditions. A specified color does not establish a universal thermal rating.
How soon can I receive a quotation?
Complete drawing-led inquiries typically receive a quotation in 2–3 working days. Engineering questions are clarified first so the quote covers the correct material, machining, finish, testing and packaging.
Send the essentials and get a focused engineering response.
