Lightweight: about 1/3 the weight of iron, steel, copper or brass, making aluminum extrusions easier to handle, less expensive to ship, and an attractive material for use in applications where weight reduction is a priority such as transportation and other applications involving moving parts.
 

Strong: can be made as strong as needed for most applications and, due to the nature of the extrusion process, the strength can be concentrated where it is really needed by including varying wall thicknesses and internal reinforcement in the profile design.
 

positive sustainability benefits due to their recyclability, recycled content and geographically disbursed production network (reducing transport fuel and emissions), often their greatest environmental benefit comes in use, i.e.: from the reductions in environmental impact realized from more efficient products.
