Aluminum Industry Standards

United States' aluminum industry standards, which are voluntary, have been developed and continue to evolve to meet the need for a communication system to facilitate aluminum commerce.

The structure for this communication system is defined by seven American National Standards Institute (ANSI) H35 Standards, some of which authorize The Aluminum Association to administer the registration of chemical composition limits and mechanical properties, with accompanying assignment of alloy and temper designations.

The ANSI standards are developed under approval by the American National Standards Committee H35, Aluminum and Aluminum Alloys, which is an ANSI accredited standards committee. Aluminum Association standards are promulgated by the Technical Committee on Product Standards (TCPS).

In addition to registering alloy compositions and designations, the TCPS also registers alloy-temper product standards. Most industry product standards information for aluminum mill products is published in Aluminum Standards and Data (available in both customary and metric editions).

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).
