Aluminum Sheet Metal Gauge Tolerance

5052 aluminum h32.

Aluminum sheet metal gauge tolerance.

The aluminum sheet metal thickness can be divided into four categories. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075. Super thick sheets mm. History of the gauge system the gauge system has long history in metal fabrication.

Sheet metal guage tolerances. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. It s also important when working with sheet metal that you factor in finish tolerances. For example if you add a finish such as powdercoat you add more thickness this should be factored into your design at the beginning.

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. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges.
