Understanding the Aluminum Temper Designation System

Abstract

This chapter provides additional detail and illustrations for the use of temper designations in the aluminum industry today for both wrought and cast alloys. This discussion expands on the basic Aluminum Association Temper Designation System as described in Chapter 2. All standard tempers (i.e., those recognized by the industry because they have been registered by the Aluminum Association Technical Committee on Product Standards) are published either in Aluminum Standards and Data or in the Alloy and Temper Registration Records together with the procedures for registering alloys.
