Approximate thickness in millimeters.
Mild steel sheet metal gauge thickness.
The larger the gauge number the thinner the metal.
Now to find the maximum capacity for aluminum simply multiply the thickness of your mild steel by 1 5.
The gauge number 18 holds no relevance to the actual measurements.
Approximate thickness in fractions of an inch.
So a 20 gauge brake has a maximum bending capacity of 036.
Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge.

Sheet metal thickness gauges for steel are based on a weight of 41 82 pounds per square foot per inch of thickness.
Gauge to thickness chart click here for a printable pdf chart gauge.
As the gauge number increases the material thickness decreases.
For other materials such as aluminum and brass the thicknesses will be different.
1 ft2 0 0929 m2 1 lb 0 4536 kg.
In the u s the thickness of sheet metal is commonly specified by a traditional non linear measure known as its gauge.
For example 20 gauge mild steel is 036 thick.
The maximum capacity of a sheet metal brake or shear is based on the total thickness gauge of mild steel at its full length.
Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper.
Gauge and weight chart for sheet steel galvanized steel stainless steel aluminum and strip tubing.
A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.
For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.
This is known as the manufacturers standard gage for sheet steel.
