Naval Brass 464 / C464 / C46400

ASTM B171, ASTM B21, ASME SB171, BS 2870 CZ113, BS 2874 CZ113, BS 2875 CZ113, EN CW719R

Farmer’s Copper Ltd. keeps on hand a hefty stock of lead-free C464 naval brass, available in plate & sheet, diamond cut plate, and rod & bar. C46400 possesses great resistance to seawater, making it ideal for salt and fresh water immersion in either stagnant or moving water. 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. Copper Alloy 464 has uses for decorative fittings, turnbuckles, shafting, and as a universal non-corrosive marine alloy.

Typical Applications for C46400

  • Valve Stems
  • Propeller Shafts
  • Ship Equipment
  • Tooling Plates
  • Wear Plates
  • Heat exchanger tube sheets and baffles
