Copper alloy naval brass pipe C46400, a high-strength pipe material suitable for marine environments where strength and seawater resistance are critical. It is a copper-zinc alloy with a controlled addition of tin that offers greater resistance to corrosion, erosion and dezincification than conventional brass. The alloy can be used for parts subjected to continuous water flow, mechanical loads and harsh conditions. C46400 pipes can be produced in different forms: seamless pipe, extruded pipe, cold-drawn pipe, heavy wall pipe, which can meet different dimensional and engineering requirements. They have a broad range of applications in marine pressure-retaining components, shipbuilding, offshore equipment, and shaft sleeves. USA Piping Solution is a manufacturer and supplier of C46400 Naval Brass Pipes with material certification and traceability for marine and industrial applications throughout the world.
