Abstract

Sets out designation systems to identify grades of wrought aluminium and aluminium alloys and their tempers. Full chemical compositions are included for wrought grades currently available in Australia.
RECONFIRMATION NOTICE
Major stakeholders of this publication have reviewed the content of this publication and in accordance with Standards Australia procedures for reconfirmation, it has been determined that the publication is still valid and does not require change.
Certain documents referenced in the publication may have been amended since the original date of publication. Users are advised to ensure that they are using the latest versions of such documents as appropriate, unless advised otherwise in this Reconfirmation Notice.

Scope

This Standard provides a listing of wrought aluminium and aluminium alloys currently available in Australia and defines the temper designation system for aluminium and aluminium alloys that have been strain hardened, with or without supplementary thermal treatments, or thermally treated, with or without supplementary strain-hardening. This Standard specifies chemical composition limits for all designated grades. Requirements for other properties are specified in Standards that cover product types.
