Extrusion advantage:
1. High strength-to-weight ratio
Because the extrusion process "puts the metal where it is needed," the result is a very strong part with relatively low weight.
2. Light weight
The weight of aluminum is approximately one-third that of copper or brass or steel.
3. Corrosion resistance
Aluminum has exceptionally good corrosion-resistance properties. It is self-protected by its own thin, transparent oxide film. Aluminum's natural protective properties and color can be enhanced by chemical or electrochemical means.
4. Machines at high speed
Aluminum is normally machined at speeds of 600 to 700 surfaces per minute and can usually be machined on standard equipment. Special lubricants, cutters and tools have been developed for aluminum to permit machining at even higher speeds.
5. Easily joined
Aluminum alloys can be joined by welding, brazing, soldering, adhesive bonding, mechanical fastening by stakin, as well as by the use of nuts, bolts, rivets, etc.
6. Formed easily
Extruded shapes can be formed or bent using conventional equipment. Minimum radii and other specific points depend on a number of considerations: alloy, wall thickness, temper and shape.  
7. High electrical conductivity
On a weight-to-weight basis, aluminum carries twice the current of copper. On a size-to-size basis, aluminum carries two-thirds the current of copper at considerably lower cost.
8. Excellent thermal properties
Aluminum is both a good heat conductor and a good heat reflector. Its ability to conduct heat is almost equal to that of the best conductors: silver, copper, and gold. Because of its ability to conduct heat, aluminum is used in heat transfer applications. And, because aluminum is also highly light reflective, it is used as a heat shield.
