For more than 60 years the aluminum association has worked with the industry to develop and maintain technical standards for aluminum production. Below you will find the tolerances for plates an sheets according to alloy group. 2011 t3 2024 t4 6061 t6 t651 cold finish.

The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances. These rods are precision ground and held to a strict straightness tolerance so they re ready for turning in a lathe. When working with sheet metal it is common for the term gauge to be used someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel for example. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.

To help this blog will explain the gauge system and features a sheet metal gauge chart.
