What is Naval Brass?

Naval brass is a copper alloy consisting of approximately 59% copper, 40% zinc, and 1% tin, with trace amounts of lead. It belongs to the Alpha Beta, or Duplex, Brass subfamily, which is known for being harder and stronger than other types of brass.

Originally developed for use in seawater applications, Naval Brass includes tin to enhance its corrosion resistance. The lead content improves the alloy’s machinability. C464 Naval Brass Rod offers moderate machinability, at around 35% compared to Free Machining Brass.
