![]() ![]() Typical Uses for C46400 Naval Brass "Lead-Free":ĮLECTRICAL: Precision Shipboard Equipment The alloy is also noted for its resistance to wear, fatigue, galling, and stress corrosion cracking. 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. By substituting tin for an equal quantity of zinc, a high corrosion resistance to seawater is achieved. As is typical of brass alloys with the duplex alpha + beta structure, C46400 has good strength and rigidity. Naval Brass C46400 is nominally composed of 60% copper, 39.2% zinc, and 0.8% tin.
