Stamping Blanks

Good copper stamping starts with the blank itself. If the metal's too thin it warps under your dies. Too thick and you're fighting every strike. Our blanks are cut from 16oz copper — roughly 24 gauge — which hits that sweet spot where the material takes clean impressions without buckling or cracking at the edges.

We stock circles, ovals, rectangles, crescents, hearts, stars, and strips. Most of our customers are jewelers and craft artists making pendants, charms, tags, and keychains. A few buy the larger sheets and strips for architectural accent work or custom flashing details. The raw copper surface takes stamps beautifully and patinas on its own over time, or you can force a finish with liver of sulfur if you want that aged look right away.

Buy high-quality metal stamping blanks for use in arts and crafts, custom jewelry, designs and more. Copper and stainless steel options. Everything ships uncoated and unpolished — raw copper, ready for your tools. Packs of 10 on most shapes, wholesale lots available on the popular sizes. If you need a shape or dimension we don't list, reach out. We cut custom runs regularly.
