Import Aluminum Extrusion Heat Sink For Lighting — Buy in wholesale FOB from Supplier in China

This aluminum extrusion heat sink for lighting is a compact thermal management component measuring 8.5 cm by 3.8 cm and weighing 170.1 grams, manufactured from Aluminum Alloy 6063-T5 (ASTM B221). The extrusion process forms finned or profiled geometry that increases surface area for convective heat transfer, a critical requirement for LED modules and conventional lamp fixtures where junction temperature directly affects lumen maintenance and operational life. The 6063-T5 temper designation indicates solution heat-treated and artificially aged material, delivering typical yield strength of 145 MPa and excellent extrudability for complex cross-sections.

The 6063 alloy composition contains magnesium (0.45-0.9%) and silicon (0.20-0.60%), forming Mg2Si precipitates during aging that strengthen the matrix while preserving thermal conductivity typically around 200-220 W/(m.K) at 25 degrees C. For lighting applications, this alloy balances the need for structural rigidity in fixture mounting with sufficient thermal diffusivity to spread heat from LED arrays or driver electronics. Standard industry practice for comparable heat sinks includes anodising (Type II or Type III per MIL-A-8625) to enhance emissivity and corrosion resistance, though the supplier's stated surface treatment reads only as 'on', requiring clarification. The 8.5 x 3.8 cm footprint suits downlights, track lighting heads, and small panel light housings where space constraints limit heatsink volume.

Buyers in LED fixture manufacturing, commercial lighting distribution, and industrial lamp refurbishment source this component for integration into finished products. The extrusion process allows for cost-effective production at volume, with typical minimum order quantities for custom profiles ranging from 500 to 3000 metres depending on die complexity. Importers should confirm whether Dongguan Jeefly offers cut-to-length finishing, deburring, and thermal interface preparation (such as flatness machining for direct LED module contact). The supplier's location in Dongguan, Guangdong Province, places it within China's principal aluminum extrusion manufacturing cluster, with access to raw material suppliers and surface treatment subcontractors.

Dongguan Jeefly Hardware Co. Ltd is located in Liaobu, Dongguan, Guangdong Province, China, with the address listed as Xiabian, Liaobu, Dongguan, 510000. The supplier holds a 'harbor' trust tier designation, which represents a baseline verification level on the platform. The response rate is recorded at 0.00% with an average response time of 0 hours, indicating that this supplier has not responded to buyer enquiries through the platform's messaging system. Buyers should treat this as a significant due diligence flag and plan to establish direct communication channels before committing to orders.

The listing presents itself as a hardware manufacturer focused on aluminum extrusion products for lighting thermal management. No factory size, year of establishment, annual revenue, export licence details, or client references are provided in the available data. The supplier's description emphasises cost-effectiveness for lighting manufacturing operations, but does not indicate in-house CNC machining, surface treatment capabilities, or quality management certifications such as ISO 9001. Importers should verify production capacity, existing export experience, and whether the company operates as a direct manufacturer or trading intermediary, as the profile does not clarify organisational structure or ownership of extrusion presses.
