Common Aluminum Sheet Metal Gauges

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.

Common aluminum sheet metal gauges.

Fuel tanks food chemical handling trailer siding roofing etc. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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. If your project does not have any physical or structural demands and the aesthetics are not important then almost any aluminum grade will do the job.

Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet. Mill finish not polished. When working with sheet metal it is common for the term gauge to be used someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel for example. Ryerson offers heat treatable aluminum sheet grades like the popular 6061 aluminum alloy that can be used for commercial applications that require strength corrosion resistance and machinability as well as non heat treatable grades when formability and weldability are priorities.

This is known as the manufacturers standard gage for sheet steel. Aluminum is a general purpose alloy commonly used in extrusions and is also available in sheet metal. Metal gauges below you ll find the info you need with our sheet steel stainless steel and aluminum sheet metal charts. General information of aluminum sheet thickness.

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. 3003 aluminum sheet has a smooth semi shiny finish and is popular for many applications including. For other materials such as aluminum and brass the thicknesses will be different. 3003 h14 aluminum sheet astm b209 qq a 250 2 excellent weldability and formability with good corrosion resistance makes 3003 aluminum sheet a popular and economical choice.

The larger the gauge number the thinner the metal. Aluminum is a common metal used for both industrial and non industrial applications. 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.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. 6061 aluminum is also very easy to machine. Aluminum sheet metal comes in a variety of thicknesses and weights in many different grades. Use the chart below to convert standard gauge numbers in decimals of an inch for sheet steel aluminum and stainless steel.

In most cases it can be difficult to choose the correct aluminum grade for your intended application.
