STANDARDS ACTION REPORT
January 2021 RECENT STANDARDS ACTIONS 2021 EDITION OF THE “STANDARDS FOR ALUMINUM SAND AND PERMANENT MOLD CASTINGS” PUBLISHED The 16th edition of the Standards for Aluminum Sand and Permanent Mold Castings has been published. This publication is the definitive resource for standardizing the entire gamut of technical criteria and conditions pertinent to the world of Aluminum casting, enabling optimal communication between purchasers and manufacturers in terms of design and fabrication. The Standards for Aluminum Sand and Permanent Mold Castings contains two sections:
Among numerous corrections and updates, this latest edition improves upon the multitude of tolerances specified within the Engineering Series by providing examples for tolerance calculation, along with the addition of precision flatness tolerances for sand molds. The discontinuity level requirements specified in the Aluminum Casting Quality Standard have been updated. The edition also comprehensively builds upon the properties of Aluminum alloys relevant to casting today, including the addition of popular cast alloys such as A206. The Standards for Aluminum Sand and Permanent Mold Castings is available in print and in digital download and may be ordered from the Aluminum Association online bookstore at www.aluminum.org/bookstore. The cost is $60 for members and $120 for non-members. RECENT STANDARDS ACTIONS The Aluminum Association completed registration of two (2) new alloys/tempers A206-T4 and A206-T7, castings and one (1) new international wrought alloy 6035. In addition, the association registered five (5) new powder alloys 2A05.50, 2A05.51, 2A05.60L, 2A05.61L, 2B05.50 and 2B05.60. Note: The chemical composition limits of the registered alloys since the last edition of the Teal Sheets, Purple Sheets and the Yellow and Tan Sheets are listed in the addenda of this publication are available at http://www.aluminum.org/resources/industry-standards. |

The majority of the Association’s standards activities are carried out by the Technical Committee on Product Standards (TCPS) in accordance with The Aluminum Association procedures governing these activities. Product Divisions may also form technical committees to work on specific standards that affect their products. For example, the Electrical Division has a Task Group of AA Representatives on National Electrical Code Panels.
