Key Features and CNC Machining Applications

Excellent Materials:

extruded heat sinks are primarily made from highly thermally conductive aluminum alloys (e.g., 6063, 6061) or copper. Aluminum is favored for its light weight and cost-effectiveness, while copper offers superior thermal conductivity under extreme heat loads.

CNC Precision Machining:

Complex Geometries: CNC milling and drilling techniques enable precise fabrication of complex fin arrays, microchannels, and custom profiles to maximize surface area and enhance convection.

Surface Finishing: CNC controlled tools achieve uniform roughness for improved thermal interface contact and coating adhesion.

Threaded Holes and Mounting Features: CNC ensures precise alignment of screw holes and brackets for seamless integration with PCBs or chassis.

Advanced Surface Finishing:

Anodizing: Electrochemical oxidation (e.g., black anodizing) increases emissivity (up to 0.9) and corrosion resistance, which is critical for LED lighting and outdoor applications.

Sandblasting: Increases surface roughness for enhanced airflow turbulence and heat dissipation efficiency.

Powder coating: provides aesthetic customization and additional protection from environmental wear and tear.

Applications across industries

High-quality extruded heat sinks are essential in the following areas:

Electronics: Cooling of CPUs, GPUs, and power modules in servers and telecommunications equipment

Automotive: Thermal management of electric vehicle batteries, LED headlights, and on-board chargers

Industrial systems: Cooling of laser diodes, power converters, and renewable energy inverters
