Standards: ASTM B-21, ASTM B-124, ASTM B-171, SAE J461, SAE J463, SAE 73, AMS 4611, AMS 4612, DIN 3.053

Naval Brass C46400 is nominally composed of 60% copper, 39.2% zinc, and 0.8% tin. As is typical of brass alloys with the duplex alpha + beta structure, C46400 has 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 alloy an inherent resistance to dezincification, thereby further inhibiting the impingement by seawater at higher than normal temperatures. The alloy is also noted for its resistance to wear, fatigue, galling, and stress corrosion cracking.
