FOREWORD

Listed in this booklet are the tempers for aluminum and aluminum alloy products registered with The Aluminum Association but not contained in The Association's Aluminum Standards and Data.

Some of the registered tempers may be the subject of U.S. patents or patent applications, and their listing herein is not to be construed in any way as the granting of a license under such patent rights.

Tempers for wrought products are given on pages 1-27 and for castings on page 28. Inactive alloys and tempers are listed on pages 32-38.

An explanation for The Aluminum Association's "Temper Designation System" is given in the Aluminum Standards and Data and in the American National Standard ANSI H35.1.

All new registrations and changes to previously registered mechanical property limits are marked and defined. In addition, the registration column also includes a revision date to indicate changes to the property limits originally registered.
