| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Temper annealed 675 °C / 2–6 h, air cooled | Mandatory for critical seawater parts: decomposes continuous κIII/β networks and suppresses selective de-aluminification. | 260 | 630 | 20 | 155 HB | 7.2 % IACS |
GSDefault Sand cast | Standard route for large propellers, pump casings and one-off heavy sections. | 270 | 650 | 18 | 160 HB | 7 % IACS |
Chill (permanent mould) cast | Faster cooling gives finer structure and higher strength for medium-size repeat parts. | 300 | 700 | 16 | 170 HB | 7 % IACS |
Centrifugally cast | Choose for dense, porosity-free bushings, wear rings and large-diameter sleeves. | 300 | 700 | 16 | 170 HB | 7 % IACS |

What is CC333G?
CC333G (CuAl10Fe5Ni5-C, equivalent to C95800 and ZCuAl10Fe5Ni5) is a high-strength nickel-aluminum bronze casting alloy from the C90000–C95999 family. It is the standard choice where seawater corrosion, cavitation and erosion resistance must combine with 650 MPa tensile, 270 MPa yield, 18 % elongation and 160 HB, and it carries a corrosion resistance score of 82. Supplied as sand, centrifugal and continuous castings, including the TA temper-annealed condition. Machinability is low, roughly 30 % of AISI 1212, and heavy sections need controlled feeding; for higher hardness at the cost of ductility see CC334G. CC333G has a density of 7.6 g/cm³ (0.275 lb/in³), lighter than 93% of copper alloy grades. It melts at 1,043°C (1,909 °F). CC333G has a yield strength of 270 MPa (39.2 ksi) and a tensile strength of 650 MPa (94.3 ksi) — stronger than 56% of copper alloy grades. Elongation at break is 18% and the elastic modulus is 117 GPa (17 Msi).

Working with CC333G
Is CC333G easy to machine?
Tough, gummy chips — use sharp positive-rake carbide, rigid setups, moderate speed (60–120 m/min) with generous coolant; rating ≈30 % of AISI 1212.
Can CC333G be welded?
GTAW/GMAW with matching CuAl10Fe5Ni5 filler, 150–250 °C preheat and interpass ≤300 °C; remove oxide film, post-weld 675 °C temper anneal for seawater duty.
Can CC333G be formed, bent or molded?
Casting alloy only — control gating/feeding to avoid oxide films and shrinkage; not cold formable, but hot working at 850–950 °C is possible for wrought equivalents.
CC333G chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on CC333G?
Not anodizable; parts are shot-blasted and machined, then protected by the natural passive film, epoxy/antifouling coatings or cathodic protection; polishes to a bright bronze lustre.

CC333G — frequently asked
What is CC333G used for?
CC333G is typically used for ship propellers, seawater pump impellers, offshore valve bodies and cavitation-resistant components. In short: standard marine propeller bronze; best seawater cavitation resistance; weldable and repairable castings.
What is the yield strength of CC333G?
CC333G has a typical yield strength of 270 MPa (39.2 ksi) and a tensile strength of 650 MPa (94.3 ksi) — stronger than 56% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.
Is CC333G easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% of copper alloy grades). Tough, gummy chips — use sharp positive-rake carbide, rigid setups, moderate speed (60–120 m/min) with generous coolant; rating ≈30 % of AISI 1212.
Can CC333G be welded?
Yes — weldability is rated very good (70/100). GTAW/GMAW with matching CuAl10Fe5Ni5 filler, 150–250 °C preheat and interpass ≤300 °C; remove oxide film, post-weld 675 °C temper anneal for seawater duty.

What is the maximum service temperature of CC333G?
CC333G 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 CC333G-GS and CC333G-GM?
GS is the default condition — standard route for large propellers, pump casings and one-off heavy sections. GM: faster cooling gives finer structure and higher strength for medium-size repeat parts. Yield strength is 270 MPa in GS versus 300 MPa in GM.
