Aluminum Sheet Metal Gauge Tolerances

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

Aluminum sheet metal gauge tolerances.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Conversion data chart standard gauges chart gauge tolerance chart useful data page. Gauge nominal in mm max in mm min in mm 10. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.

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. Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions.

For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Steel sheet metal tolerances. As a registered iso 9001 2015 company rolled steel products state of the art equipment meets virtually any requirement in panel flat quality leveling precision slitting close tolerance sheet blanking strip quality edge conditioning precision shearing and complete cold reducing capabilities.

The larger the gauge number the thinner the metal. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075.
