Compare all 5 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Sand cast, stress relieved | Use when heavy welded/repaired castings must be dimensionally stable or free of residual stress before final machining. | 130 | 290 | 28 | 75 HB | 10.5 % IACS |
GSDefault Sand cast | Standard route for valve bodies, pump casings and flanges of any size; most commonly stocked/ordered condition. | 140 | 300 | 25 | 80 HB | 10 % IACS |
Permanent (gravity die) cast | Choose for repeat small/medium fittings where faster solidification gives finer grain, tighter tolerances and slightly higher strength. | 150 | 310 | 25 | 85 HB | 10 % IACS |
Continuously cast | Bar and hollow stock for machined seawater fittings; uniform fine structure with good machining behaviour. | 155 | 320 | 25 | 88 HB | 10 % IACS |
Centrifugally cast | Best for seawater pipe spools, sleeves and bushings — dense, porosity-free wall with the highest cast strength. | 160 | 330 | 25 | 90 HB | 10 % IACS |
What is CC380H?
CC380H is the European cast 90-10 copper-nickel (CuNi10Fe1Mn1-C, equivalent to C96200), with iron and manganese additions for erosion-corrosion resistance in seawater. It is produced as sand (GS), die (GM), centrifugal (GZ) and continuous (GC) castings, and in a stress-relieved GS-SR condition, for valve bodies, pump casings and flanges, with 140 MPa yield, 300 MPa tensile, 25 % elongation and 80 HB. Service is limited to 300 °C, electrical conductivity is only 10 % IACS, and machinability is about 20 % of free-cutting brass; CC381H (70-30) is the step up where higher strength or flow velocity is required. CC380H has a density of 8.9 g/cm³ (0.322 lb/in³), heavier than 77% of copper alloy grades. It melts at 1,100°C (2,012 °F). CC380H has a yield strength of 140 MPa (20.3 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 74% of copper alloy grades. Elongation at break is 25% and the elastic modulus is 124 GPa (18 Msi).

Working with CC380H
Is CC380H easy to machine?
Gummy and work-hardening — use sharp positive-rake carbide, low speed with heavy feed, ample coolant and rigid setups; rating ≈20 % of free-cutting brass.
Can CC380H be welded?
Readily GTAW/GMAW welded with CuNi 70/30 (ERCuNi) filler; keep interpass low, no preheat needed, avoid lead/sulphur contamination and back-purge for root passes.
Can CC380H be formed, bent or molded?
Cast only — needs good gating/risering, Mn-Si deoxidation and controlled pour temperature (~1250 °C) to avoid gas porosity and shrinkage.
CC380H 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 CC380H?
Not anodizable; usually supplied bare so the protective seawater film can form, or lightly pickled/shot blasted; electroplating and silver brazing are both feasible.

CC380H — frequently asked
What is CC380H used for?
CC380H is typically used for seawater valve bodies, marine pump casings, flanges and offshore piping fittings. In short: standard seawater casting alloy; strong biofouling resistance; lower-cost cast Cu-Ni.
What is the yield strength of CC380H?
CC380H has a typical yield strength of 140 MPa (20.3 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 74% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.
Is CC380H easy to machine?
Not especially — machinability is rated poor (28/100, worse than 78% of copper alloy grades). Gummy and work-hardening — use sharp positive-rake carbide, low speed with heavy feed, ample coolant and rigid setups; rating ≈20 % of free-cutting brass.
Can CC380H be welded?
Yes — weldability is rated very good (80/100). Readily GTAW/GMAW welded with CuNi 70/30 (ERCuNi) filler; keep interpass low, no preheat needed, avoid lead/sulphur contamination and back-purge for root passes.

What is the maximum service temperature of CC380H?
CC380H 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 CC380H-GS and CC380H-GZ?
GS is the default condition — standard route for valve bodies, pump casings and flanges of any size; most commonly stocked/ordered condition. GZ: best for seawater pipe spools, sleeves and bushings — dense, porosity-free wall with the highest cast strength. Yield strength is 140 MPa in GS versus 160 MPa in GZ.
