Aluminum Sheet Metal Thickness Tolerance Standard

A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

Aluminum sheet metal thickness tolerance standard.

Deviation allowed for the specified width. We work with nominal thicknesses so it s important to know the thickness tolerance on the material you chose in order to know if the final product will be suitable for your application. General information of aluminum sheet thickness. The aluminum sheet metal thickness can be divided into four categories.

During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. Standard tolerances for aluminum usually choosing material thickness is one of the first steps a designer takes when starting a project. 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. Tolerance in.

For other materials such as aluminum and brass the thicknesses will be different. Astm a240 a480 steel sheet sthickness tolerance. Thus a 10 gauge steel sheet which has a thickness of 0 1345 inches will weigh. Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric. For example 18 gauge steel according to a gauge conversion chart is 0. Aluminum sheet thickness tolerances xls author. This is known as the manufacturers standard gage for sheet steel.
