2. Sheet metal - Wikipedia

   en.wikipedia.org/wiki/Sheet_metal

   In most of the world, sheet metal thickness is consistently specified in millimeters. In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

3. Shear (sheet metal) - Wikipedia

   en.wikipedia.org/wiki/Shear_(sheet_metal)

   A power shear is electrically or pneumatically powered hand tool designed to blank large pieces of sheet metal. They are designed to cut straight lines and relatively large radius curves. They are advantageous over a bandsaw because there is not a size limit. Large versions can cut sheet metal up to 12 gauge. [5]

   The thickness ranges is the tolerance chart do not line up properly with the gauge column and the values are not in agreement with the thickness chart. — Preceding unsigned comment added by 134.24.147.249 ( talk ) 12:38, 29 January 2015 (UTC) [ reply ]

5. Rolling (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Rolling_(metalworking)

   For thin sheet metal with a thickness less than 200 μm (0.0079 in), [citation needed] the rolling is done in a cluster mill because the small thickness requires a small diameter rolls. [10] To reduce the need for small rolls pack rolling is used, which rolls multiple sheets together to increase the effective starting thickness.

6. Aluminium alloy - Wikipedia

   en.wikipedia.org/wiki/Aluminium_alloy

   The second moment of area is proportional to the cube of the radius times the wall thickness, thus increasing the radius (and weight) by 26% will lead to a halving of the wall stress. For this reason, bicycle frames made of aluminium alloys make use of larger tube diameters than steel or titanium in order to yield the desired stiffness and ...
