You may have seen our list of standard materials which are part of our online quoting system. But for many of our clients involved in making jewelry, fine art, or interior design, these materials aren't what they're looking for.  For them (and anyone who wants a material not on the list) we do custom orders. Popular materials in these fields include copper, brass, and silver. On these projects, the thickness of the material is frequently specified in gauge, rather than inches or millimeters.

At Big Blue Saw, we turn raw copper, brass, and other stock into custom parts from YOUR designs made using waterjet cutting. For an instant quote on your design, try our online quoting and ordering system.

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. It's based on the American or Brown and Sharpe Wire Gauge standard. As with steel, as the gauge gets higher, the thickness gets lower. Unlike with steel, I can't find a set standard for tolerances for sheets of this material. This means that you're at the mercy of the manufacturer and distributor for tolerances here. (If you know of such a standard, please let me know.)

Here's a chart showing wire gauges in inches and millimeters.

Also, galvanized steel sheet also has its own set of gauge thicknesses:

Zinc sheet has yet another gauge system for thickness. I can't recall a single customer who ever wanted us to make something out of zinc sheet, so I'll leave that for you to find on your own. Machinery's Handbook is an authoritative source, and has a chart which includes zinc sheet gauges.

If you're having trouble picking out a thickness, take a look at our page on deciding on a material thickness.

Keep in mind that some manufacturers, distributors, and end users get the gauge thickness wrong. They might use the wrong metal's gauge chart or pick an obsolete standard when labeling a sheet of material. That's why we suggest working with thicknesses in common, unambiguous units like millimeters or inches.
