The Aluminum Association has updated three of its registration records commonly known as the Teal, Pink and Light Green Sheets, which are available in the Association Bookstore.
The Teal Sheets: International Alloy Designations and Chemical Composition Limits for Wrought Aluminum and Wrought Aluminum Alloys — This registration record is the defining source for the designations and chemical composition limits for wrought aluminum and wrought aluminum alloys referenced in a number of standards and specifications worldwide. The 2018 edition contains 20 new alloys and one newly inactive alloy.
The Pink Sheets: Designations and Chemical Composition Limits for Aluminum Alloys in the Form of Castings and Ingot — This registration record contains designations and chemical composition limits registered with the Association for aluminum and aluminum alloys in the form of castings and ingot. In the latest 2018 edition, 34 new alloys were added, two alloys were inactivated, and one new footnote was added. This version supersedes the previous 2009 edition.
The Light Green Sheets: Components of Clad Aluminum Alloy Products — This publication is the registration record for clad aluminum alloy products registered with The Aluminum Association, and contains the registered designations, component alloys, cladding location, and other information. The new version of this publication has one new clad alloy combination and removed four others.
All three registration records are available digitally or as a hard copy.
Association designations and product standards information are used throughout aluminum commerce, as well as in other organizations’ codes and standards. Aluminum alloy and temper designations, chemical composition limits, and registered properties in the U.S. all originate from the aforementioned system of ANSI and Aluminum Association standards. These standards are also the basis for international agreements for the worldwide producer registration of wrought alloys, unalloyed aluminum, and aluminum hardeners.
