The Pink Sheets, Designations and Chemical Composition Limits for Aluminum Alloys in the Form of Castings and Ingot (revised August 2025, superseding October 2018), record the registered designations and chemical composition limits for cast aluminum alloys. The contents include the registered designations and limits, footnotes, inactive alloys, the registered chemical composition limits of inactive original alloys, a cross reference of current and former designations, and the recommendation of the Association. Foundries, casting buyers and specifiers use the record to confirm the composition range attached to a designation such as 356.0 or A356.0, and to trace older designations that have been superseded.
