Extruded Heat Sinks provide a greater range of natural convection solutions for higher power components and systems. Complex fin structures can be created by forcing raw aluminum through an extrusion die. These complex fin profiles allow greater heat dissipation through increased surface area while eliminating the cost and time associated with machining an equivalent shape from block aluminum.

More efficient than stamped heat sinks
Lower cost than fully machined assemblies
Many standard shapes and sizes assure availability
Easily customized for any application
Significant weight advantage over copper
Extruded heat sinks are the "utility infielder" of our industry. They are relatively inexpensive, once a design is made the manufacturing is highly automated, and, in most cases, aluminum is the material used. Aluminum is cheap and a relatively good thermal conductor. They are used for most general applications, depending on the design, fin pitch and base thickness they can be low to high performers, and, as I mentioned earlier, they are cost effective.  The basic con is they are limited in their dimensions being that they are based on an aluminum extrusion with a given width
