Ultra Thin Brass Sheet 0.3–0.8 mm, Cut to Size

Ultra Thin Brass Sheet for Fine Work

RapidKeen ultra thin brass sheet covers the softest, most formable brass in our range, from 0.3 mm to 0.8 mm. This is the gauge to reach for when a part has to wrap, bend tightly, emboss, etch or sit invisibly behind another surface — thin enough to fold by hand, yet still a full flat brass sheet rather than coiled foil.

Why This Thickness Range

Very formable

Soft annealed 0.3–0.8 mm brass bends, folds and wraps by hand without a press, and holds a clean radius around tight corners.

Clean surface

Mill finish is consistent across the sheet, ready for polishing, patina, lacquer or painting.

Joins easily

Solders, brazes and glues cleanly — no heavy fixtures needed for small assemblies.

Won't rust

Indoors or sheltered outdoors, brass holds its tone without the rusting of steel sheet.
