Brass sheet for craft jewelry these are special alloys of copper zinc made to resemble gold more about this in sheet metal jeweler s bronze sheet right has deep gold color is also known as 230 brass and is 85 copper. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. In an earlier article we took a look at the standard gauges for steel sheet.
Gauge when applied to copper brass or silver means a different set of thicknesses however. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. Unlike with steel i can t find a set. As with steel as the gauge gets higher the thickness gets lower.
It is the same alloy as our jewelers bronze wire. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Stainless steel is 0 105 thick aluminum is 0 080 copper is 0 108 and brass is 0 081. It is important to know that the gauge thicknesses also vary depending on the type of sheet metal being referenced.
