Alloys : Aluminum Alloy

Alloys are composite materials comprised of multiple compatible metals to form a new material, the alloy. Aluminum alloys are ones in which aluminum is the primary metal and are typically characterized as either cast or wrought alloys. The materials selected to be combined with the aluminum vary based on the desire to improve strength, ductility, formability, weldability, or corrosion resistance. Aluminum alloys are very popular in the aircraft industry due to their high strength-to-weight ratios.
