Copper Sheet Gage Thickness

Copper thickness for example is measured in ounces representing the weight of copper contained in an area of one square foot.

Copper sheet gage thickness.

40 mil 18 gauge 040 18 gauge copper sheeting is heavyweight copper. It is approximately twice as thick as 22 mil copper and weighs approximately 2 pounds per square foot. 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. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter.

Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge to thickness chart gauge stainless galvanized sheet steel aluminum fraction inches mm inches mm inches mm inches mm 30 0 0125 0 33 0 0157 0 40 0 0120 0 30 0 0100 0 25. 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.

Gauge differs between ferrous iron based metals and nonferrous metals such as aluminum or copper. 8 gauge 4 115 mm. For different materials of steel the same gauge will also correspond to different mm. It is approximately twice as thick as 22 mil copper and weighs approximately 2 pounds per square foot.

It s based on the american or brown and sharpe wire gauge standard. 8 gauge 4 191 mm aluminum brass copper. Unlike with steel i can t find a set standard for tolerances for sheets of this material.
