Abstract

This standard provides systems for designating wrought aluminum and wrought aluminum alloys, aluminum and aluminum alloys in the form of cast ings and foundry ingot, and the tempers in which aluminum and aluminum alloy wrought products and aluminum alloy castings are produced. Specifi c limits for chemical compositions and for mechanical and physical properties to which conformance is required are provided by applicable product standards. <br>NOTE: A numerical designation assigned in conformance with this stan dard should only be used to indicate an aluminum or an aluminum alloy having chemical composi tion limits identical to those registered with The Alumi num Association and, for wrought aluminum and wrought aluminum alloys, with the signatories of the Declaration of Accord on an International Alloy Designation System for Wrought Aluminum and Wrought Aluminum Alloys.
