Cylindrical Aluminum Heat Sink

• 360-Degree Heat Dissipation: Cylindrical design maximizes surface exposure for uniform, all-around heat dissipation, ideal for enclosed or vertical installations.
• High-Grade Aluminum Alloy: Manufactured using A6063 or A6061 aluminum for excellent thermal conductivity, corrosion resistance, and structural durability.
• Space-Efficient Profile: Compact round shape enables efficient cooling in confined spaces or tubular housings such as LED lights and power modules.
• Surface Finish Flexibility: Available with anodized, powder-coated, or mill finish options to enhance appearance, oxidation resistance, and thermal radiation.
• Robust Mechanical Structure: Offers good impact resistance, high formability, and dimensional stability under thermal cycling conditions.
• OEM Customization Available: Supports fully customized outer diameter, wall thickness, slot patterns, and end-cap integration based on customer design.
• Tool-Free Assembly Potential: Round shape supports press-fit or twist-lock installations in compatible enclosures, reducing assembly time and cost.

• Material Options: A6063, A6061, or client-specified aluminum grades
• Outer Diameter: From 20mm to 200mm or custom sizes available
• Wall Thickness: Typically 1mm to 5mm; customizable for strength or thermal needs
• Fin Design: Internal or external fins, straight or spiral; slot spacing and depth can be customized
• Surface Finishes: Clear/silver anodizing, black anodizing, powder coating, or raw mill finish
• Mounting Options: Press-fit, adhesive, or mechanical screw/bracket integration
• Machining Support: CNC drilling, tapping, slotting, or end-cut machining available
• MOQ: 200kg per specification
• Lead Time: 15-25 working days depending on complexity
