Cut Oxidized Bronze

Oxidized Bronze numbers and letters are water-jet cut from flat sheets of bronze in the various thicknesses mentioned in the table above. The faces of these pieces are then brushed. The returns are bead-blasted. The pieces are then oxidized by submersion in a chemical solution to darken the bronze into either a medium or dark finish.

For the final step, the returns are tinted a very dark brown and then the faces and returns are clear-coated and baked with a glossy 2-part hardened acrylic polyurethane clear coat.

Our solid, oxidized, bronze numbers and letters are water-jet cut from lead and mercury-free alloy NAVY G 88-8-0-4 (nominal: Cu 88 Sn 8 Zn 4).

NOTE: The oxidized bronze finish will darken over time. This process is accelerated in damp or marine environments. For a fixed color of medium or dark bronze oxidation, please consider medium or dark-bronze anodized aluminum.
