Extruded Aluminum Heatsinks
Extruded aluminum heatsinks from Guangzhou Ruiju E-commerce Co., Ltd. are manufactured using Aluminum Alloy 6063-T5 and 6061-T6, offering thermal conductivity values of approximately 180 W/mK and 165 W/mK respectively. These alloys are selected for their balance of thermal performance, machinability, and corrosion resistance in industrial environments. Dimensions are customizable but typically range from 20mm to 150mm in length, with fin thicknesses between 0.8mm and 2.0mm and base thicknesses from 2mm to 5mm, based on the extrusion profile.
The heatsinks are produced through precision die extrusion, followed by straightening, aging, and surface treatment. Anodizing is available as a standard option, increasing surface hardness and oxidation resistance without compromising thermal transfer. Painted finishes are offered for aesthetic or environmental protection needs. These are not generic components but engineered for specific thermal loads, with fin density and base geometry optimized for airflow dynamics in enclosed electronic housings.
These heatsinks are commonly purchased by manufacturers of LED lighting systems, power converters, telecommunications equipment, and industrial control units. Buyers typically require batch sizes from 500 to 5,000 units per order, with packaging in corrugated cardboard or custom foam inserts to prevent surface scratching. Trade terms include FOB Guangzhou or CIF to major ports, with lead times of 15 to 25 days after confirmation of drawings and payment. Custom profiles require tooling approval before production begins.
| Material | Aluminum Alloy 6063-T5 / 6061-T6 |
| Thermal Conductivity | 165 W/mK to 180 W/mK, typical for 6061-T6 and 6063-T5 alloys |
| Fin Thickness | 0.8mm to 2.0mm, typical range for extruded heatsinks |
| Base Thickness | 2mm to 5mm, typical for structural rigidity and thermal spread |
| Fin Height | 10mm to 80mm, typical for airflow optimization in electronics |
| Fin Density | 4 to 12 fins per inch, standard for balanced thermal resistance and airflow |
| Surface Finish | As-extruded, anodized, or painted; anodizing typically 10 to 25 microns thick |
| Tolerance on Dimensions | ±0.1mm on critical dimensions, typical for precision extrusion |
| Weight per Unit | Varies by profile; typical range 50g to 800g depending on size and fin count |
| Maximum Operating Temperature | 120°C continuous, standard for aluminum alloys under load |
Guangzhou Ruiju E-commerce Co., Ltd. is based in Tianhe District, Guangzhou, Guangdong, with a registered address at Room 401, Building 9, No. 200 Yuangang Road. The company operates as a supplier of extruded aluminum components with a focus on thermal management products. The listing indicates no verified factory inspection reports, no production capacity figures, and no direct manufacturing history is disclosed. The supplier is classified as 'harbor' tier, suggesting a basic level of platform verification but no third-party audit confirmation.
There is no public information on workforce size, years in operation, export volume, or client list. The company does not list certifications such as ISO 9001 or IATF 16949 on the profile. The response rate and average response time are both recorded as zero, indicating no documented buyer interactions. Buyers should treat this as a trading entity that sources or coordinates extruded heatsinks rather than a verified manufacturer. Direct communication with the supplier is required to confirm production capability and quality control procedures.
Our extruded aluminum heatsinks are engineered for superior thermal management across electronics, LED lighting, power supplies, and telecommunications applications. Manufactured from high-grade aluminum alloys such as 6063 and 6061, these heatsinks offer excellent thermal conductivity and corrosion resistance with custom extrusion profiles. Available in standard and custom dimensions, they are ideal for B2B buyers seeking reliable, cost-effective heat dissipation solutions for import and distribution.

Sourcing Extruded Aluminum Heatsinks from Guangzhou Ruiju E-commerce Co., Ltd. - China Import Guide
Before placing an order, verify the exact alloy composition and temper designation through a material test report. Confirm that the supplier can produce the required fin geometry and base thickness to match your thermal model. Request a sample for thermal performance validation under real operating conditions. Do not rely on generic product descriptions - demand detailed engineering drawings with tolerances and surface finish requirements.
Lead time is typically 15 to 25 days after drawing approval. Confirm whether the supplier uses FOB Guangzhou or CIF terms, and clarify who is responsible for export documentation and insurance. Payment terms are usually 30% advance, 70% against copy of bill of lading. Ask for packaging details: whether heatsinks are individually wrapped, stacked with spacers, or packed in bulk. Request photos of packed shipments to assess protection against damage.
Perform incoming quality inspection using a digital caliper to verify critical dimensions and a thermal imaging camera to test heat spread uniformity. Check for surface scratches, burrs, or uneven anodizing. Request batch-specific mill test reports and ensure compliance with RoHS if used in regulated markets. Retain a sample from each shipment for traceability. Document all inspection results with photos and measurements before accepting delivery.
