Aluminum profile-heat sink mill finish

Product Introduction

What can we know about Aluminum heatsink ?

Aluminum heatsinks offer a great balance of performance, weight, and cost, making them the most popular choice for general cooling needs. For extreme thermal demands, copper or hybrid designs may be better, but aluminum remains the go-to for most applications.

Why we choose Aluminum heatsink ?

1. High Thermal Conductivity

• Aluminum has a thermal conductivity of around 205–250 W/m·K, efficiently transferring heat away from components.

• While not as conductive as copper (~385 W/m·K), it offers a good balance between performance and cost.

2. Lightweight

• Aluminum is about three times lighter than copper, making it ideal for applications where weight matters (e.g., electronics, automotive, aerospace).

3. Cost-Effective

• Cheaper than copper while still providing effective cooling.

• Easier to manufacture in bulk via extrusion or die-casting.

4. Corrosion Resistance

• Naturally forms a protective oxide layer, preventing rust and degradation.

• Can be anodized for enhanced durability and aesthetics.

5. Easy to Manufacture

• Can be extruded into complex shapes with fins for better heat dissipation.

• Also suitable for die-casting and stamping for custom designs.

6. Good Heat Dissipation Surface

• Large surface area with fins improves convection cooling (especially when paired with fans).

• Can be combined with heat pipes for high-performance cooling.

7. Recyclable & Environmentally Friendly

• Aluminum is 100% recyclable without losing quality, reducing environmental impact.
