What is CC332G?
CC332G (CuAl10Ni3Fe2-C, equivalent to C95400 and ZCuAl10Fe3Mn2) is a nickel-modified cast aluminum bronze in the C90000–C95999 family, with nickel raising strength and erosion resistance over plain aluminum bronze. Castings give 570 MPa tensile, 250 MPa yield, 20 % elongation and 120 HB, with service to 300 °C, which suits pumps and valves handling seawater and abrasive slurries. Available as castings only; heat-treated (HT) condition is on file. It machines slowly with abrasive, continuous chips, and for the most severe cavitation duty CC333G nickel-aluminum bronze is the next step. CC332G has a density of 7.5 g/cm³ (0.271 lb/in³), lighter than 98% of copper alloy grades. It melts at 1,040°C (1,904 °F). CC332G has a yield strength of 250 MPa (36.3 ksi) and a tensile strength of 570 MPa (82.7 ksi) — stronger than 54% of copper alloy grades. Elongation at break is 20% and the elastic modulus is 110 GPa (16 Msi).

Working with CC332G
Is CC332G easy to machine?
Machines like a tough duplex bronze: rigid setup, positive-rake carbide, 60–120 m/min, moderate feed and generous coolant; chips are continuous and abrasive on tooling.
Can CC332G be welded?
Readily GTAW/GMAW welded with matching CuAl10Ni or CuAl9Ni5 filler, preheat 150–250 °C for heavy sections; keep interpass low and avoid slow cooling through 550–450 °C to limit γ2 formation.
Can CC332G be formed, bent or molded?
Foundry alloy only — bottom/tangential gating with generous filtration to trap alumina films; feed with chills, no meaningful cold forming, hot working only 800–900 °C.

What surface finishes work on CC332G?
Pickle in dilute sulfuric/nitric to remove the alumina skin before painting; takes a bright polish but oxidises to an olive-brown patina; do not anodise, use epoxy or antifouling coatings in seawater.

CC332G — frequently asked
What is CC332G used for?
CC332G is typically used for pump impellers, valve bodies, marine propeller hubs and wear plates. In short: nickel-strengthened cast aluminum bronze; seawater erosion resistance; weldable with matching filler.
What is the yield strength of CC332G?
CC332G has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 570 MPa (82.7 ksi) — stronger than 54% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.
Is CC332G easy to machine?
Reasonably — machinability is rated good (55/100, better than 71% of copper alloy grades). Machines like a tough duplex bronze: rigid setup, positive-rake carbide, 60–120 m/min, moderate feed and generous coolant; chips are continuous and abrasive on tooling.
Can CC332G be welded?
Yes — weldability is rated good (65/100). Readily GTAW/GMAW welded with matching CuAl10Ni or CuAl9Ni5 filler, preheat 150–250 °C for heavy sections; keep interpass low and avoid slow cooling through 550–450 °C to limit γ2 formation.

What is the maximum service temperature of CC332G?
CC332G is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between CC332G-GS and CC332G-HT?
GS is the default condition — default condition for pump casings, valve bodies and large one-off marine castings. HT: optional treatment (common on C95400-type castings) for maximum hardness and wear resistance, and to remove γ2 for better dealloying resistance; ductility drops sharply. Yield strength is 250 MPa in GS versus 400 MPa in HT.
