The Gold Sheets, International Designations and Chemical Composition Limits for Unalloyed Aluminum (revised August 2025, superseding the January 2018 edition), form part of the Aluminum Association's Registration Record Series. After a foreword and the signatories to the Declaration of Accord, the record lists the registered designations and chemical composition limits for unalloyed aluminum, with explanatory footnotes, the inactive registration list, and the recommendation to the Declaration of Accord. It is the reference used by producers, specifiers and purchasers who need the internationally agreed composition limits behind designations such as 1050, 1100 or 1235.
