Values for the GS condition
CC330G tempers and conditions
CC330G is supplied in 5 conditions, soft to hard. GS is the default FabDigit quotes; the values on this page are for it.
Compare all 5 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Annealed | Applied after welding or heavy machining to relieve residual stress and homogenise α; slightly softer, more ductile, better dimensional stability. | 185 | 480 | 30 | 100 HB | 14 % IACS |
GSDefault Sand cast | Standard route for pump/valve bodies and large one-off housings; lowest cooling rate, coarsest grain, highest ductility relative to strength. | 200 | 500 | 25 | 110 HB | 13 % IACS |
Continuously cast bar/tube | Stock semi-finished bar and hollow for machined bushings and fittings; uniform fine structure and best machining consistency. | 215 | 540 | 25 | 115 HB | 13 % IACS |
Permanent mould (chill) cast | Choose for medium-series small/medium parts where the finer chill-cast grain gives ~10 % higher strength and better surface. | 220 | 550 | 25 | 120 HB | 13 % IACS |
Centrifugally cast | Best for bushings, sleeves and ring-shaped valve seats — dense, dross-free wall with directional solidification. | 220 | 550 | 25 | 120 HB | 13 % IACS |

Working with CC330G
Is CC330G easy to machine?
Gummy, continuous chips — use sharp positive-rake carbide, moderate speed (60–120 m/min), heavy feed and flood coolant; rates about 40–50 % of free-cutting brass.
Can CC330G be welded?
One of the most weldable cast bronzes: GTAW/GMAW with CuAl9 (ERCuAl-A2) filler, preheat 150–250 °C on heavy sections, remove oxide film and interpass dross carefully.
Can CC330G be formed, bent or molded?
Cast only — bottom gate with generous risers, degassed and skim-protected melt to control Al₂O₃ dross; avoid slow cooling in heavy sections to limit γ2 and dealuminification risk.
CC330G 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.

|---|---|---|
| Al | 8 – 10.5 | 9 |
| Feresidual; higher Fe refines grain | ≤ 1 | 0.4 |

CC330G — frequently asked
What is CC330G used for?
CC330G is typically used for valve bodies, pump housings, marine fittings and bushings. In short: most weldable cast bronze; low-cost aluminium bronze casting; 500 MPa with 25% elongation.
What is the yield strength of CC330G?
CC330G has a typical yield strength of 200 MPa (29 ksi) and a tensile strength of 500 MPa (72.5 ksi) — weaker than 54% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.
Is CC330G easy to machine?
Not especially — machinability is rated fair (42/100, better than 59% of copper alloy grades). Gummy, continuous chips — use sharp positive-rake carbide, moderate speed (60–120 m/min), heavy feed and flood coolant; rates about 40–50 % of free-cutting brass.
Can CC330G be welded?
Yes — weldability is rated very good (78/100). One of the most weldable cast bronzes: GTAW/GMAW with CuAl9 (ERCuAl-A2) filler, preheat 150–250 °C on heavy sections, remove oxide film and interpass dross carefully.

What is the maximum service temperature of CC330G?
CC330G 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 CC330G-GS and CC330G-GM?
GS is the default condition — standard route for pump/valve bodies and large one-off housings; lowest cooling rate, coarsest grain, highest ductility relative to strength. GM: choose for medium-series small/medium parts where the finer chill-cast grain gives ~10 % higher strength and better surface. Yield strength is 200 MPa in GS versus 220 MPa in GM.
