What is a Cold Forged Heat Sink?

A Cold Forged Heat Sink is a precision metal cooling component manufactured through room-temperature cold forging. This process shapes metal billets under high pressure into dense fin structures without secondary machining, achieving ultra-thin fins (as low as 0.5mm) and optimized thermal conductivity. Ideal for scenarios demanding lightweight design, corrosion resistance, and high heat dissipation efficiency.

Key Features of Cold Forged Heat Sinks

Superior Thermal Performance
- High-density fins (1.0-3.0mm spacing) increase surface area by 30-50% vs. extruded heatsinks.
- Refined grain structure from cold forging enhances thermal conductivity by 5-10%.
Structural Integrity
- Seamless monolithic design with 20% higher vibration resistance compared to die-cast alternatives.
- Surface roughness Ra ≤0.8μm minimizes contact thermal resistance.
Material Versatility
- Compatible with aluminum alloys (6061/6063) for lightweight applications or copper alloys (C1100) for extreme thermal loads.
- Optional surface treatments: anodizing (500+ hours salt spray resistance), micro-arc oxidation.
