Heat Sink Thermal Extrusions

Wakefield Thermal Heat Sink Thermal Extrusions are available in 1- and 3-foot lengths and are the most common heat sinks used for thermal management. These heat sinks are manufactured by pushing hot aluminum billets through a steel die to produce the final shape. Extruded heat sinks are usually supplied with a finish such as anodizing, which can enhance their thermal performance. Wakefield Thermal Heat Sink Thermal Extrusions are engineered to achieve optimal thermal and structural performance.
