Alloy 464 Naval Brass Sheet and Plate (UNS C46400) is a high-strength copper-zinc alloy containing approximately 60% copper, 39% zinc, and a small addition of tin for enhanced corrosion resistance. The tin content improves resistance to dezincification and saltwater exposure, making it well suited for marine and industrial environments. Supplied in flat sheet and plate form, it provides uniform thickness for structural fabrication and precision cutting. Thinner sheet is commonly used for formed components, while thicker plate is selected for load-bearing or heavy-duty applications.

Marine: Structural mounting plates, saltwater-exposed covers and guards, structual reinforcement plates for ship repairs, corrosion-resistant façade panels and pump and valve wear plates
