extrusion aluminum high power led heat sink 

Extruded Aluminum heat sink is one of the most popular and cost-efficient fabrications. Extruded aluminum heat sink range in size based on application, smaller for board level or larger for medium power applications. They can be designed for passive or active cooling based on fin shape and pitch. Board level extruded heat sinks are common for packages such as BGAs and FPGAs.Choosing the right extruded aluminum heat sink is largely based on the profile needed. Extruded aluminum heats sinks are made by creating a profile die that determines fin density, pitch, and length, as well as the base height and width. Softened aluminum is pushed through the extrusion die to create a long bar, known as a raw bar, with the same custom aluminum extrusion profile and size as the die. The bar is then cut into smaller, standard shaped bars/rectangles or custom lengths. These are further machined and finished to create customized aluminum heat sink. This process is fast, cost-efficient, and scala…
