Materials for Efficient and Durable Heat Sinks

Whether aluminum, copper, or stainless steel – we select the optimal material for each heat sink to ensure maximum thermal conductivity, stability, and durability.

Selected Materials – for Maximum Efficiency and Reliability

Choosing the right material is crucial for the performance of air and liquid coolers. In addition to excellent thermal conductivity, heat sinks must be corrosion-resistant and mechanically stable. We advise you on which material and alloy best suit your specific requirements.

Aluminum

Aluminum is the preferred material for manufacturing heat sinks and liquid cooling plates in power electronics. It offers excellent thermal conductivity, low weight, and high corrosion resistance, making it ideal for a wide range of cooling applications.

Copper

Copper provides extremely high thermal and electrical conductivity – about twice that of aluminum. This allows for highly efficient heat dissipation, ideal for applications with high power density and limited space.
