Aluminum sheet thickness tolerance.

General information of aluminum sheet thickness. For more than 60 years the aluminum association has worked with the industry to develop and maintain technical standards for aluminum production. 2011 t3 2024 t4 6061 t6 t651 cold finish. The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker.

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. 4 20 2009 11 06 07 am.
