Extruded heat sinks are usually supplied with a “finish” such as anodizing which can enhance its thermal performance. The heat sinks can also be supplied with a chromate finish which provides some corrosion protection or can be used as a primer before a final paint or powder coating is applied. While each extruded shape is unique to the requirements that it was designed for, extruded heat sinks are the most cost-effective cooling solution. Each shape is engineered to achieve the optimal thermal and structural performance.
