For those of us who buy our copper and brass in large quantities from commercial metals companies, you may have encountered an odd way they measure thickness for our metal. At our local store, Industrial Metals, the sheets have “oz” measurements. If you’ve forgotten to bring your B&S metal gauge (remember the one for steel is not the same as the one for non-ferrous metals) you may not know what you are getting. Here’s a handy chart to keep on your phone or print out for your car so you always know what gauge you are buying. It’s a jpg so feel free to download it as you need.
