What Are the Benefits of Anodized Aluminum Heat Sinks?

Heat sinks play an important role in electronic and mechanical devices. They act as passive heat exchangers, transferring heat from hot components to a fluid medium (usually air).

Aluminum heat sinks are commonly anodized.

Anodizing is a surface treatment process that uses electrochemistry to form a layer of Al2O3 (aluminum oxide) film on the surface of aluminum and aluminum alloy. Through anodic oxidation, the surface state and performance of the material can be changed, thus improving corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface.

Some of the key benefits of anodized aluminum heat sinks are:
 

• Improved Corrosion Resistance
• Improved Wear Resistance
• Increased Electrical Isolation
• Improved Surface Emissivity
