DESCRIPTION

Naval brass is the classic marine, high-strength and corrosion-resistant alloy containing 60 percent copper, .75 percent tin and 39.2 percent zinc. The addition of Tin also gives Naval Brass a high resistance to dezincification. It is widely used in marine construction where strong, corrosive-resistant and hard material is required and is suitable for both salt and fresh water applications. Naval Brasses have good strength and rigidity. The alloys are noted for their resistance to wear, fatigue and stress corrosion cracking.
