Aluminum Alloys

Metals where the dominant alloying element is aluminum (Al, also spelled aluminium). Aluminum alloys are subdivided by fabrication method (wrought or cast, typically). Wrought alloys are further subdivided by series or composition family.

Wrought aluminum alloys are identified by a 4-digit integer Aluminum Association designation. In European standards, the same number is prepended with "EN AW-". Casting alloys use different designation systems in Europe and North America.
