AMS: 4611, 4612
Alloy Description: Naval Brass
UK: BS2871, CZ133
EU: CuZn39Sn1

This moderate-strength alloy is also known as naval brass. Wrought strengthening and the addition of tin gives this alloy an inherent resistance to dezincification, greatly inhibiting seawater corrosion at higher-than-normal temperatures. C46400 Naval Brass is also noted for its resistance to wear, fatigue, galling, and stress corrosion cracking. C46400 Brass is used are mainly in seawater applications such as deck hardware, lock pins, pump and valve stem nuts, heat exchanger tubes, and propeller shafts.


  • Moderate corrosion resistance in sea water
  • Moderate strength properties
  • Excellent machinability
  • Good impact resistance
