Naval Brasses are nominally composed of 60% copper, 39.2% zinc and 0.8% tin. As are typical of brass alloys . Naval brasses have good strength and rigidity. By substituting tin for an equal quantity of zinc, a high corrosion resistance to seawater is achieved. The addition of tin also gives the C486 alloys an inherent resistance to dezincification, thereby further inhibiting the impingement by seawater at higher than normal temperatures. The alloys are also noted for its resistance to wear, fatigue, galling, and stress corrosion cracking.
