Aluminum uniquely combines thermal conductivity, cost efficiency, and durability. Thanks to a wide range of alloys and machining options, it remains the preferred material for efficient heatsinks and liquid cooling plates in modern power electronics.
-
Excellent Thermal Conductivity
With a thermal conductivity of about 200 W/mK, aluminum efficiently dissipates heat, making it ideal for applications where reliable thermal management is critical.
-
Low Weight and High Stability
Aluminum significantly reduces the total weight of the cooling system – a major advantage in aerospace, automotive, and mobile devices.
-
Natural Corrosion Resistance
The formation of a protective oxide layer makes aluminum highly resistant to moisture and coolants – ideal for long-lasting liquid cooling plates.
-
Cost Efficiency and Sustainability
Compared to copper, aluminum is much more affordable and almost infinitely recyclable, offering both ecological and economic benefits.
