FOREWORDListedherein are designations and chemical composition limits for wrought aluminum andwrought aluminum alloys registered with The Aluminum Association. Numerical designationsare assigned in accordance with the Recommendation—International Designation System forWrought Aluminum and Wrought Aluminum Alloys, which is printed on pages 28 through 30.Additions may be made in accordance with the rules outlined in the Declaration of Accordprinted on page 31, and alloys will be deleted when no longer in commercial use (see table ofinactive alloys printed on pages 22-23).Effective July/2015, the practice of registering experimental alloys has been discontinued andnew experimental alloy designations shall not be granted. Prior to July/2015, designations forexperimental alloys, defined by prefix “X,” had been registered in accordance with the systemdefined in ANSI H35.1, “American National Standard Alloy and Temper Designation Systemsfor Aluminum.” Previously registered and subsequently inactivated experimental alloys remainin the Previously Assigned but Presently Inactive Alloy Designation list. An experimental alloycomposition shall retain the prefix “X” for the duration of its inactive status and can only bereactivated with removal of the experimental alloy status and prefix “X.”Some of the registered alloys may be the subject of patent or patent applications, andtheir listing herein is not to be construed in any way as the granting of a license undersuch patent right.This registration record is not intended to address all regulatory requirements that maybe imposed by local, national or international governing bodies. Regulatoryrequirements, which vary by region and end use, can further restrict the chemicalcomposition within the registered limits. When applicable, inclusion of suchrequirements in the sales agreement is advised.Alist of the organizations that are signatories to the Declaration of Accord on theRecommendation is printed on pages ii-iii.i
