Heatsink Extrusions

High performance extrusion with the highest dimensional flexibility.

Our heatsinks are manufactured by pushing hot aluminium billets through a steel die to produce the final shape. Extruded heatsinks are usually supplied with a finish such as anodising, which can enhance the heatsinks thermal performance. GD Rectifiers heatsink extrusions are engineered to achieve optimal thermal and structural performance.

An extrusion for high-quality heatsink profiles always starts from a careful tooling design. The set up of the extrusion tooling is carried out by specialised personnel with extensive experience. Accurate inspection of the dimensions, the mechanical properties and the chemical composition are guaranteed for a high-quality product.

Each aluminium alloy has its own physical, chemical and mechanical characteristics which make it suitable for specific applications. We require versatile and machinable extruded heatsink profiles and rely on 6060/6063 Al-Mg-Si alloys, together with its good anodising characteristics.

We offer the largest range of profiles with more than 160 standard free toolings. In addition we hold a wide range of heatsink profiles in stock in our warehouse which can be accessed to meet your urgent and small quantity requirements. Our technical team can help and advise in the development of new profiles, according to your requirements and application.

Browse the heatsink range by device type, part number or comparison guide. The comparison guide allows you to compare the various sizes of each device. GD Rectifiers offer technical support on all heatsinks including specific heat dissipation requirements.
