Aluminum Alloy and Temper Designation Systems of the Aluminum Association

Abstract

It is very useful for secondary fabricators and users of aluminum products and components to have a working knowledge of the Aluminum Association alloy and temper designation systems. The alloy system provides a standard form for alloy identification that enables the user to understand a great deal about the chemical composition and characteristics of the alloy. Similarly, the temper designation system permits an understanding of the manner in which the product has been fabricated.
