January 28, 2021
Today, the Aluminum Association released the 16th edition of Standards for Aluminum Sand and Permanent Mold Castings. The first update since 2008, this new edition is an essential guide for anyone who works with aluminum castings. A definitive resource for standardizing the entire gamut of technical criteria and conditions, the publication facilitates optimal communication between purchasers and manufacturers in terms of design and fabrication. Print and digital versions are available at  
“This critical update to the only publication on the market focused on aluminum sand and permanent mold castings, the 16th edition consolidates all the latest standards and data in one location,” said Tom Dobbins, president & CEO of the Aluminum Association. “Updates on tolerances, technical definitions, new alloys and more make this an indispensable publication for those involved in the aluminum casting industry. This is just one of a comprehensive library of standards the association maintains to give designers the tools that they need to make good products great and great products even better with aluminum.”  
The Standards for Aluminum Sand and Permanent Mold Castings contains two sections:
  • ENGINEERING SERIES (E): This section establishes metrics for the various tolerances, precisions, allowances and finishes applicable to unmachined cast aluminum products;
  • METALLURGICAL SERIES (M): This section delves into the properties of the various aluminum alloys and tempers frequently used in casting, and the metallurgical requirements to cast products of desired quality.  
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 has 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 can be purchased from the Aluminum Association online bookstore at  The price is $60 for members of the Aluminum Association and $120 for non-members.
