Copper Sheet Metal Thickness Tolerance
Sheet metal guage tolerances.
Copper sheet metal thickness tolerance. The 16 mil is approximately 1 5 times thicker than the 10 mil. Fabrication tolerances for dimensional variance in sheet metal and machined parts standard tolerances for copper usually choosing material thickness is one of the first steps a designer takes when starting a project. Gague are used to specify the thickness of a metal sheet. 16 mil 016 inches thick 26 gauge.
The annealing temperature of 110 copper is 700 1200 f. Also called 26 gauge the 16 mil copper weighs approximately 12 ounces per square foot. A tolerance of 48 000 0 125 inches by 96 000 0 125 inches is much quicker to produce and can be done at a lower cost. The sheet metal does however have a tolerance on the rolling thickness which needs to be taken into account when designing a tight fitting assembly especially as the sheet metal material gets thicker.
The tolerances in the table and attachments reflect current manufacturing practices and commercial standards and are not representative of the manufacturer s standard gauge which has no inherent tolerances. Sheet metal is manufactured and delivered from the processing mill rolled to the standard thickness that you specify which is now metric. At american metal supply we provide the chart to calculate thickness and sheet tolerance in inches and the weight for various gauges. It would take approximately 62 5 sheets of 16 milstacked on top of each other to make an inch.
They might use the wrong metal s gauge chart or pick an obsolete standard when labeling a sheet of material. The recommended hot working temperature for 110 copper is 1400 1600 f. Sheet metal gauge thickness chart 2019 10 24t01 36 33 00 00 when working with sheet metal the term gauge is often used. If the application can still be successful with a wider ranging metal tolerance then that is usually the best option.
Keep in mind that some manufacturers distributors and end users get the gauge thickness wrong. During the rolling process the rollers bow slightly which results in the sheets being thinner on the edges. If you re having trouble picking out a thickness take a look at our page on deciding on a material thickness. Oxygen free coppers are made for welding operations if needed.
