Aluminum Extrusion Heat Sink
This aluminum extrusion heat sink measures 18 by 9.5 centimetres and weighs 367.5 grams, manufactured from 6063 or 6061 grade alloy via aluminum extrusion process with spray black paint surface treatment. The black finish enhances emissivity for improved_wrapper improved thermal radiation performance in LED luminaires, switch-mode power supplies, and industrial control equipment. The compact form factor suits applications where PCB mounting space is constrained but steady-state thermal dissipation of 5-15 watts typical is required.
The extrusion process forms fins from a solid billet under high pressure through a hardened steel die, allowing aspect ratios of fin height to gap width up to 10:1 for natural convection designs. 6063 alloy, with typical thermal conductivity of 200-220 W/(m·K), is preferred for heat sinks due to excellent extrudability and fin detail definition. The spray black paint finish typically achieves emissivity of 0.85-0.90 compared to 0.04-0.08 for bare aluminum, significantly improving radiative heat transfer at moderate temperatures where convection alone is insufficient.
OEM buyers in LED lighting, telecommunications, and industrial automation sectors use this profile for thermal management of MOSFETs, IGBTs, and LED COB arrays. The supplier indicates flexibility for custom dimensions and surface treatments beyond the standard black painted finish. Buyers should confirm fin density, base thickness, and mounting hole patterns against their thermal simulation requirements, as these are not specified in the source data.

Sourcing Aluminum Extrusion Heat Sink from Dongguan Jeefly Hardware Co. Ltd - China Import Guide
Before ordering, verify the exact alloy grade and obtain a mill test certificate showing chemical composition to GB/T 3190 or EN 573-3. Request dimensional inspection report for a production sample, measuring overall dimensions, weight, and critical features against your drawing. Confirm the paint formulation and supplier's testing for adhesion, hardness, and thermal cycling. Given the 0.00 percent response rate, establish direct communication channels (alternative contact persons, instant messaging platforms used in China) and confirm sample lead time before committing to production volume.
Shipments from Dongguan typically depart via Shenzhen or Guangzhou Port, with Hong Kong as an alternative for air freight. Confirm Incoterms (EXW Dongguan, FOB Shenzhen, or CIF destination) and whether the supplier has export license and experience with your destination country's customs requirements. Payment structures for hardware suppliers in this region commonly involve 30 percent deposit, 70 percent before shipment for established buyers, or 100 percent LC at sight for new relationships. Negotiate tooling cost amortisation if custom extrusion dies are required, and confirm who retains die ownership.
On receipt, inspect for dimensional conformance (length, width, height, weight), surface finish uniformity, and paint adhesion using simple tape test. Check base flatness with a precision straightedge or feeler gauge, as poor flatness will negate thermal interface material effectiveness. Request batch-specific test reports and retain samples for potential metallurgical analysis. For ongoing supply, consider periodic factory audits and incoming inspection protocols to maintain consistency, particularly if thermal performance is critical to product reliability and warranty obligations.
