AA Standard For Aluminium Alloys

Aluminum Association designations and product standards information are used throughout all facets of aluminum commerce, as well as in other organizations’ codes and standards. Aluminum alloy and temper designations, chemical composition limits and registered properties in North America, all originate from the above system of ANSI and AA standards. These standards are also the basis for several international agreements for the worldwide producer registration of wrought alloys, unalloyed aluminum, and aluminum hardeners (aluminum alloy materials and grain refiners).
