Aluminum Sheet Metal Gauge Tolerance

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.
Aluminum sheet metal gauge tolerance. 5052 aluminum h32. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel. 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 aluminum sheet metal thickness can be divided into four categories. 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. Sheet metal guage tolerances. Super thick sheets mm.
During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075.
