Copper sheet gage thickness.

Gauge when applied to copper brass or silver means a different set of thicknesses however. 8 gauge 4 191 mm aluminum brass copper. It is approximately twice as thick as 22 mil copper and weighs approximately 2 pounds per square foot. 8 gauge 4 176 mm stainless steel.

It s based on the american or brown and sharpe wire gauge standard. Unlike with steel i can t find a set standard for tolerances for sheets of this material. For different materials of steel the same gauge will also correspond to different mm. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 40 mil 18 gauge 040 18 gauge copper sheeting is heavyweight copper. As with steel as the gauge gets higher the thickness gets lower.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. Copper thickness for example is measured in ounces representing the weight of copper contained in an area of one square foot.
