Aluminum Sheet Metal Gauge Tolerances

Gauge nominal in mm max in mm min in mm 10.

Aluminum sheet metal gauge tolerances.

The larger the gauge number the thinner the metal. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. General information of aluminum sheet thickness. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick.

Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.

An aluminum sheet metal thickness refers to the thickness of an aluminium sheets a flat square or rectangle piece of aluminum material with a thickness of between 0 2mm and 500mm a width of 200mm some are even 50mm and above and more and a length of 16m or less.

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

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. In most of the world sheet metal thickness is consistently specified in millimeters.
