Copper Heat Sink

• Exceptional Thermal Conductivity: Copper’s thermal conductivity (~400 W/m·K) is approximately twice that of aluminum, enabling rapid and efficient heat transfer.
• Superior Durability & Corrosion Resistance: Copper excels in maintaining performance under high humidity, elevated temperatures, and accelerated thermal cycling environments.
• Precision Shaping & Material Versatility: Copper can be processed into intricate geometries via skiving, CNC machining, stamping, or soldering-even allowing composite structures such as copper-aluminum integration.
• Compact & High-Performance Designs: Skived-fin copper heat sinks achieve ultra-high fin density and aspect ratios, delivering maximal surface area for cooling in minimal space.
• Long-Term Reliability: Copper’s resistance to biofouling, oxidation, and wear makes it suitable for demanding applications such as telecom, data centers, and industrial electronics.
• Scalable Production Efficiency: Copper solutions-from skived fins to composite cores-offer flexible prototyping and volume production without sacrificing thermal performance.

• Material Choices: Pure copper or copper-aluminum hybrid constructions.
• Manufacturing Processes: Options include skiving, CNC machining, stamping, and soldered stack-fin assembly.
• Geometry Customization: Tailor fin thickness, spacing, height, and density for optimal thermal performance in compact designs.
• Surface Finishes: Treatments such as passivation, plating, or coatings to enhance durability and thermal transfer.
• Heat Pipe Integration: Compatible with embedded heat pipes or vapor chambers for enhanced heat spreading.
• Volume Flexibility: Rapid prototyping for low-volume demand and cost-efficient scaling for mass production.
• OEM/ODM Support: Fully brandable with custom dimensions, packaging, and assembly options.
• Quality Assurance: Comprehensive thermal testing, material integrity checks, and surface finish verification.
