Why do we choose aluminum heat sinks ?

Aluminum vs Copper Heat Sink

Comparison Factor	Aluminum	Copper
Key Benefits	✅ 1/3 the weight of copper ✅ ~1/5 the material cost ✅ Easy to extrude/shape ✅ Corrosion-resistant (anodized)	❌ Heavy (not ideal for portables) ❌ Higher material/processing cost ✅ 68% better thermal conductivity ✅ Handles thermal spikes better
Thermal Performance	▪ Good with composite bases ▪ Effective with thin fins	▪ Superior heat transfer ▪ Needs nickel plating to prevent oxidation
Design Considerations	▪ 0.1mm thin extruded fins ▪ Unibody CNC designs	▪ Requires reinforcement ▪ Often hybrid (copper base + aluminum fins)
Best Applications	▪ Aerospace/vehicles ▪ Mass-produced electronics	▪ High-heat components (CPUs/GPUs) ▪ Overclocking setups
Cost & Production	▪ Low raw material cost ▪ High recyclability (60% lower carbon footprint)	▪ Expensive materials/processing ▪ Limited to high-end applications

Why 6 Series Aluminum Alloys Are Best for Heat Sinks

The 6xxx series aluminum alloys achieve an optimal balance within the thermal conductivity / structural strength / production cost / process compatibility trade-off framework. This makes them a universal thermal solution, employed everywhere from consumer electronics CPU coolers to industrial heat spreaders. Notably, within the extrusion sector, alloy 6063 has become the cornerstone material for performance-grade heat sinks.

Alloy Specifications

Grade	Thermal Conductivity (W/m·K)	Tensile Strength (MPa)	Characteristics
6063	200–210	180–230	Optimal overall performance; Primary choice for extruded fins
6061	170–180	290–310	Higher strength; Well-suited for heat spreader/base plate applications
6005	160–170	260–280	Balanced performance; Commonly used in automotive radiator applications

Design Recommendations

Fin Material

The preferred choice is 6063 (with good thin-wall extrusion performance).

Substrate Material

Choose 6061 (suitable for bearing weight or for drilling holes).

Key Advantage of 6 Series Alloys

The 6xxx series offers the ideal combination of thermal efficiency, mechanical strength, and manufacturing versatility that heat sink applications demand. Their extrusion-friendly properties allow for complex fin designs that maximize surface area—critical for effective heat dissipation.
