Long Aluminum Heat Sink

• Extended Cooling Surface: The long structure provides a significantly larger surface area, enhancing passive heat dissipation for high-power applications.
• High-Quality Aluminum Alloy: Made from 6063 or 6061 aluminum, combining excellent thermal conductivity with lightweight and corrosion resistance.
• Optimized Fin Design: Customizable fin geometry allows for improved airflow, reduced thermal resistance, and tailored performance across various systems.
• Sturdy and Lightweight: Long profiles retain structural integrity even with reduced weight, ideal for equipment requiring both stability and thermal control.
• Precision Extrusion Capability: Supports complex cross-sections, variable base thicknesses, and high-fin-density configurations.
• Surface Treatment Compatibility: Can be finished with anodizing, powder coating, or mill finish to enhance durability and thermal emissivity.
• Adaptable for Various Mounting Methods: Available with pre-machined holes, channels, or brackets for easy integration into industrial assemblies.

• Alloy Options: 6063-T5, 6061-T6, or customer-specified grades
• Length Range: From 100mm to over 3000mm, cut to size or continuous extrusion
• Fin Parameters: Adjustable height, pitch, and thickness to optimize convection
• Base Thickness: From 2mm to 20mm depending on load and spreading resistance
• Surface Finish: Available in anodized (black/silver), powder-coated, or mill finish
• Machining Support: Includes drilling, CNC milling, tapping, and deburring
• Mounting Interfaces: Custom holes, slots, or brackets for easy installation
• MOQ: 200kg per profile type
• Lead Time: Typically 15-25 working days
