Finned Aluminum Heat Sink

• Thin-Fin High Efficiency Design: Features ultra-thin, densely spaced fins to maximize surface area, ensuring fast and even heat dissipation in compact systems.
• Premium Aluminum Alloys: Manufactured using high-thermal-conductivity aluminum such as 6060, 6063, or 7005, balancing strength, machinability, and heat performance.
• CNC-Machined Precision: Supports milling, drilling, tapping, and trimming processes with ±0.02 mm tolerance for precise fitment and assembly.
• Durable Surface Finishes: Available in silver anodizing and custom colors; improves corrosion resistance and extends product life in indoor or outdoor environments.
• Customizable Geometry: Fin layout, base thickness, mounting holes, and size can be tailored to specific thermal design requirements.
• Reliable for Passive Cooling: Optimized for natural convection, ideal for systems requiring fanless, low-maintenance heat management.
• Secure Export Packaging: Reinforced cartons with foam and wooden supports ensure safe delivery during international transport.

• Material Options: Aluminum 6060, 6063, 7005; others available upon request
• Fin Structure: Height, spacing, angle, and thickness fully customizable
• Surface Treatment: Anodizing (silver, black, custom), polishing, drilling, and tapping
• Machining Tolerance: CNC processing with ±0.02 mm accuracy
• Profile Dimensions: Custom baseplate sizes and fin array dimensions available
• OEM Branding: Logo engraving, label printing, and design adaptation supported
• Prototyping Support: Rapid prototype service for design validation before mass production
