AMS 4611, AMS 4612, C46400, Naval Brass is a high strength and corrosion resistant alloy. It is widely used in marine construction where a strong, corrosive resistant, and hard material is required. The addition of tin gives the alloy an inherent resistance to dezincification, thereby further inhibiting the impingement by seawater at higher than normal temperatures
