What is an Extruded Heat Sink?

An extruded heat sink is created through an extrusion process. It involves forcing heated metal, typically aluminum, through a die to create continuous profiles with specific cross-sectional shapes. With this method, heat sinks are produced with well-defined fin structures, thus delivering excellent thermal conductivity.

Materials & Surface Finishes

Extrusion heat sinks combine high thermal performance with versatile material and surface finish options, ensuring reliable cooling solutions for a wide range of electronic and industrial applications.

Material

Extruded heat sinks are commonly made from aluminum alloys such as AL6063, due to their exceptional thermal conductivity, lightweight properties, and ease of machining.

Surface Finishes

Anodizing is often applied as a surface treatment to enhance corrosion resistance and surface durability. This process also improves the aesthetic appeal, providing a uniform finish for functional and visible components.

Benefits of Extrusion Heat Sinks

Cost-Effective for Mass Production

Extrusion heat sinks are recognized as an economical solution, particularly suitable for high-volume production. It keeps continuous profiles with minimal material waste in production, lowering costs while maintaining consistent quality.

Flexible Profile and Design Options

Extruded heat sinks can be tailored into a wide range of shapes, sizes, and fin structures by simply changing the extrusion die. Thanks to their flexibility, they are ideal for various thermal management needs across different industries.

Supports Secondary Machining

After extrusion, the profiles can undergo further processing such as CNC machining, drilling, or cutting. These secondary operations enable precise customization, allowing the heat sink to be adapted for specific mounting or integration requirements in complex assemblies.
