20 oz. Copper Sheet 6"X6" - Shop Seconds for Jewelry & Art.

6" x 6" 20 oz copper sheet — shop seconds from our Colorado fabrication shop.

This is real architectural copper, the same 20 oz sheet we use on custom work. These pieces are leftover drops from cutting and fabricating. They are brand-new copper, not recycled scrap and not weathered roofing.

What “seconds” means here

• New 20 oz copper
• May have fingerprints or light surface scratches from handling
• No dents
• No gouges
• Light marks usually come off with 0000 steel wool or disappear once you hammer, texture, or patina the piece

If a sheet has a crease, a ding, or a deep scratch, it does not go in this listing.

Good for Jewelry, small cuffs, pendants, stamp-and-texture studies, enamel tests, mixed-media, small vessels, tiles, and practice pieces. This is a sturdier sheet than the thin 24–26 ga jewelry blanks. It still works at the bench, but you will want snips or shears, and a brake or mallet for sharp bends.

Honest note These are priced as seconds because we will not pretend they are mill-perfect, plastic-film-protected jewelry blanks. The metal is the same copper we build with. You are buying usable shop drops at a working-artist price.

Need a different size? We also cut 12" x 12", 18" x 18", 24" x 24", and custom sizes. Message us before you order if you need a specific cut.
