Brief: Discover Precision CNC Machining China Copper Alloy Heat Sink, a high thermal conductivity cooling solution for electronic devices. Our CNC machined copper alloy heat sinks offer superior thermal management with conductivity up to 412W/m·K, oxidation resistance, and customizable designs for various applications.
Related Product Features:
  • Advanced thermal management with copper's rapid heat transfer (412W/m·K) and expanded surface designs.
  • Optimized structure using skiving technology for 0.1mm thin fins with minimized pitch for maximum density.
  • Optional EMI shielding with graphite-copper composites providing 1750W/m·K horizontal conductivity.
  • Design flexibility supporting wave-like stamping or gradient MIM manufacturing for specialized airflow.
  • Stable base compressed under 60MPa pressure achieving 99%+ density for minimal thermal resistance.
  • Pure copper (C1100) or copper alloy (C1441/C1450) materials with thermal conductivity of 401-412W/m·K.
  • Operating temperature range from -50℃ to 400℃ (standard) or 600℃ (graphite composite).
  • Customizable thickness range from 0.1-3.0mm with 0.01mm precision options available.
Faqs:
  • What are the key benefits of using copper alloy heat sinks?
    Copper alloy heat sinks offer superior thermal conductivity (up to 412W/m·K), oxidation resistance, and longevity, making them ideal for efficient heat dissipation in electronic devices.
  • Can the heat sinks be customized for specific applications?
    Yes, our heat sinks support customization in thickness (0.1-3.0mm), design (wave-like stamping or gradient MIM), and materials (pure copper or alloys) to meet specific thermal management needs.
  • What industries commonly use these heat sinks?
    These heat sinks are widely used in consumer electronics, industrial equipment, automotive electronics, LED lighting, and specialized fields like medical imaging and aerospace.
  • What is the lead time for custom orders?
    Custom orders typically have a lead time of 7-10 days, depending on the complexity and specifications of the heat sink design.
