C46400 Naval Brass Pipe is a high-strength, copper-zinc-tin alloy engineered for exceptional corrosion resistance in harsh marine environments. Known for its outstanding durability against dezincification, it maintains structural integrity under high stress and moisture. This versatile piping solution features excellent hot workability and fair cold formability, making it the industry standard for marine hardware, condenser tubes, and offshore applications.

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.
