Copper Nickel

C46400 Naval Brass

Strength and Performance in Extreme Environments

C46400, commonly known as naval brass, combines high strength, hardness, and excellent wear resistance with good machinability, making it well suited for marine and shipbuilding applications. Its robust bearing surfaces, bushings, and gears endure constant friction in hydraulic and pneumatic systems aboard vessels, while pump components and valve stems stay durable under demanding marine conditions. The alloy’s fatigue resistance and dimensional stability support precision parts for steering gear, winches, and deck machinery, as well as corrosion-resistant fittings and fasteners in saltwater environments. Additionally, its properties make it suitable for heat exchanger applications, where reliable performance and fabrication ease are essential.
