Naval Brass
Overview
C46400 is a tin-bearing brass developed specifically for marine service. The addition of tin provides superior dezincification resistance in seawater, making it the standard brass for marine fasteners, propeller shafts, and underwater hardware.
As a C46400 naval brasssupplier, Triton Bronze & Metals stocks brass in round bar, flat bar, hex bar, and more — all cut to length and shipped from US mills. Mill test reports available on request for full material traceability.
