Technical Data & Specification Review
Published parameters are reference configurations for this series. Final values are subject to approved drawings, manufacturer technical documents, samples and project inspection records.
Heat sink cross-sections can be designed as parallel fins, pin fins or comb fins based on heat flux requirements. Minimum fin spacing 1.5mm, extrusion flatness ≤0.1mm for tight contact with power devices. Surface can be silver anodized 10µm or black anodized 15µm; black anodizing increases thermal emissivity by about 30%.
6063-T5 thermal conductivity is about 201 W/(m·K). Optimized fin arrays improve heat dissipation by 3x compared to solid aluminum blocks. Base can be CNC-machined for IGBT/MOSFET mounting, thermal resistance as low as 0.1°C/W. We support thermal simulation for custom designs.

Drawing and Configuration Review
The review for aluminum heat sink profiles covers fin geometry, extrusion feasibility, flatness, machining allowances and how the profile will contact the heat-generating component. Any proposed change should be returned as a marked drawing, specification note or clarification list. Production should begin only after the customer and supplier are working from the same revision. This approach reduces ambiguity around dimensions, interfaces and responsibility for work completed at the destination.
Applications
Application 01
PV inverters, UPS, VFDs, LED street lights, 5G base stations, EV motor controllers, industrial control cabinets. Pair with motor housing heat sink profiles.
Quality Control & Inspection
Quality and Inspection Plan
Agree the inspection points before production. A practical plan may include alloy and temper records, section dimensions, straightness, finish appearance and any agreed machining checks. The required documents depend on the order and destination, so the quotation should state which reports are included and which require third-party inspection. General references can be checked through the ISO standards catalogue; the applicable project standard must still be written into the approved technical offer.
Packing & Delivery
Standard profiles in stock, ship in 3 days. Custom die fees $2,000-$4,000, 15-20 days for first article. CNC drilling, tapping, bending available up to 6m length.
A useful enquiry for aluminum heat sink profiles starts with the application rather than a catalogue photograph. Please send the section drawing, alloy and temper, thermal load, allowable envelope, cut length, surface finish and any drilling or tapping requirements. This lets the engineering team compare the requested scope with the available production route and identify information that still needs written confirmation. Where a value is not shown on an approved drawing or specification, it should be treated as open for review rather than assumed.
Export Packing and Delivery
For export orders, confirm separation of finished surfaces, moisture protection, bundle weights and labels that match the drawing revision. The commercial offer should identify the Incoterm, loading location, destination port, document set and any site work excluded from supply. Photos taken during packing may be requested as shipment records, but illustrative website images are not evidence of a completed customer project.
Comparing Quotations
Compare offers on the same technical scope. Check whether material, finishing, machining or assembly, inspection, packing, inland transport and export documents are included. A lower headline price may exclude work that must be purchased later. For aluminum heat sink profiles, send the latest drawings and destination details through the quotation form; the response should list assumptions, exclusions and items requiring confirmation before an order is accepted.
Include photographs of the installation area or comparable interfaces when they help explain access, clearance, appearance or handling constraints. They are reference inputs, not substitutes for dimensioned drawings and written acceptance criteria.
For consistent export batches, aluminum heat sink profiles should be evaluated against the same section drawing, thermal requirement and inspection plan.
For aluminum heat sink profiles, final material, dimensions, tolerances, finishes, packing and delivery terms are confirmed against the approved drawings and written technical offer.
