Common Aluminium Sheet Thickness

Aluminum from 0 008 inches to less than 0 25 inches thick is considered sheet.

Common aluminium sheet thickness. For other materials such as aluminum and brass the thicknesses will be different. In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge. Aluminum sheet thickness tolerances xls author. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

Metal foil is especially common with aluminium often referred to as tinfoil. The aluminum sheet metal thickness can be divided into four categories. 0 15 2 0 regular sheets mm. Aluminum sheet thickness tolerances 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075 1100 3003 5052 6061 2024 7075 190 007 0055 009 007.

5052 h32 aluminum sheet astm b209 qq a 250 8 superior corrosion resistance good weldability with excellent formability makes 5052 aluminum sheet a common choice for chemical marine or saltwater applications. The gauge system has long history in metal fabrication. 16 ga crs is 2 5 pounds per square foot. History of the gauge system.

6061 aluminum is also very easy to machine. Anything above that is a metal plate. The thickness of sheet metal starts from 0 5 mm and goes up to 6 mm. The thickness of foil is usually up to 0 2 mm.

Mill finish not polished. Thinner aluminum is foil and aluminum 0 250 inches and thicker is plate. For example in one gauge system 18 gauge steel measures 0 0478 inches thick but 18 gauge aluminum is 0 0403 inches thick. Sheet metal is the next in line.

Because of the varying thicknesses a gauge chart should be used to ensure the metal meets the required dimensions. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. 5052 aluminum sheet applications include. There are several different gauge systems used today with specific gauge designations used for specific metal types.

2 0 6 0 medium thick sheets mm. 6 0 25 0 thick sheets mm. The colder the stronger aluminum plate is used for storage tanks in many industries in part because some aluminum alloys gain strength at supercold temperatures. 25 200 super thick sheets mm.

The common used aluminum sheet thickness are 0 3mm 0 5mm 0 8mm 1mm 1 2mm 1 5mm 2mm 2 5mm 3mm 4mm 5mm and above. However it is not recommended for sheet metal work because it tends to crack on the outside radii once it passes its yield and therefore requires a much larger radii to be able to bend properly. The common grade of aluminium sheet are 1100 1050 1145 1060 1070 2a12 2024 3003 3a21 3004 5a05 5005 5052 5083 6a02 6061 6063 7a04 7075 8011 etc. Aluminum is a general purpose alloy commonly used in extrusions and is also available in sheet metal.

The larger the gauge number the thinner the metal.
