Conversion From Inches To Gauge In Sheet Metal

Sheet metal gauge conversions.

Conversion from inches to gauge in sheet metal. You can find the gauge to mm inch conversion for sheet metal by the chart below. The smaller the number the thicker the material. The maximum capacity of a sheet metal brake or shear is based on the total thickness gauge of mild steel at its full length. These dimensions vary slightly between different materials such as stainless steel and aluminium but should be accurate enough for most everyday purposes.

The thickness of sheet metals is specified by gauge. Sheet metal gauges work opposite to what one might consider the norm. For example 20 gauge mild steel is 036 thick. The gauge number 18 holds no relevance to the actual measurements.

Now to find the maximum capacity for aluminum simply multiply the thickness of your mild steel by 1 5. Steel galvanized and aluminum. Sheet metal gauge to mm. Sheet metal gage conversion chart inches american wire gage sizes.

The table below shows the actual thickness of sheet steel in millimetres and inches compared to gauge size. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Hence 4 gauge material is thicker than 6 gauge material.

Is different from inches there is no conversion formula. Awg decimal size. So a 20 gauge brake has a maximum bending capacity of 036.
