✦ The Optimal Alloys Difference

Why 12 gauge changes everything

⚒️

Stamps Deeper & Cleaner

The extra thickness means your stamps don't blow through or distort — each impression is crisp and defined.

💪

Holds Its Shape

Thicker gauge resists warping under the hammer, so your finished cuff keeps its elegant curve.

✨

Professional Finish

Polished to a mirror shine right out of the pack — less prep work, more selling finished pieces.

🎨

Engraver's Choice

Deeper material gives hand engravers and rotary engravers the bite they need for intricate detail.

📦

Bulk Friendly

Order from 5 pieces to 1000 — perfect whether you're a hobby artist or a production studio.

🏅

The Original

We created this product category back in 2012 — over a decade of experience in every blank we ship.

✦ Our Story

Crafted for makers, by makers

Over 12 years ago, we looked at the jewelry supply market and saw an opportunity: the industry standard 14 gauge aluminum was too thin, too flimsy, and too unforgiving under a stamping hammer. So we pioneered 12 gauge aluminum cuff blanks — and changed how artisan jewelers work.

Today, Optimal Alloys is the trusted source for hand-stampers, metal engravers, craft market artists, and jewelry studios around the world. Whether you're fulfilling a single custom order or running a full production line, we have your blanks ready to ship.

  • Premium 12 gauge aluminum — thicker than industry standard 14 gauge
  • Polished mirror finish — ready to stamp right out of the package
  • Available in 1/8″, 1/4″, 3/8″, 1/2″, 3/4″, and 1″ widths
  • Three lengths: 5″, 6″, and 7″ to fit every wrist
  • Order as few as 5 or as many as 1,000 pieces per SKU
  • Tiered bulk pricing — the more you order, the more you save
  • Fast shipping on all orders, free over $35

What crafters are saying

★★★★★

"I've tried other suppliers but I always come back to Optimal Alloys. The 12 gauge is noticeably thicker — my stamps are cleaner and my finished bracelets look so much more professional."

"Ordered 500 blanks for a holiday production run. They arrived fast, perfectly polished, and every single one was consistent. Will never order from anyone else."

★★★★★

"As an engraver, the extra thickness is everything. These blanks hold detail in a way that thinner gauge simply can't. And the bulk pricing is unbeatable for the quality."
