What is C96200?
C96200 is the standard US cast 90-10 copper-nickel (equivalent to CC380H / CuNi10Fe1Mn1-C), iron- and manganese-bearing for erosion-corrosion resistance in flowing seawater. It is widely specified for seawater valves, fittings and pump bodies, with 179 MPa yield, 317 MPa tensile, 25 % elongation and 80 HB in the as-cast condition, and is available in sand, die, centrifugal and continuous cast forms plus a stress-relieved variant. Maximum service temperature is 315 °C and electrical conductivity is only 9.5 % IACS; move to C96400 (70-30) where higher strength or flow velocity is required. C96200 has a density of 8.94 g/cm³ (0.323 lb/in³), heavier than 90% of copper alloy grades. It melts at 1,099°C (2,010 °F). C96200 has a yield strength of 179 MPa (26 ksi) and a tensile strength of 317 MPa (46 ksi) — weaker than 59% of copper alloy grades. Elongation at break is 25% and the elastic modulus is 124 GPa (18 Msi).

Working with C96200
Is C96200 easy to machine?
Gummy, work-hardening chip — use sharp positive-rake carbide, heavy positive feed, rigid setup and copious coolant; do not dwell or the surface hardens.
Can C96200 be welded?
Readily GTAW/GMAW welded with 65/30 CuNi (ERCuNi) filler; keep the weld zone clean and oxide/oil free, use low heat input, no preheat and never weld over sulfide-contaminated surfaces.
Can C96200 be formed, bent or molded?
Cast only — high solidification shrinkage (~2%) needs generous risers, chills and controlled gating; melt must be well deoxidized (Mn/Si) to avoid gas porosity and hot tearing.
C96200 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 C96200?
Not anodizable; pickle/passivate castings and allow the natural brown protective film to develop in clean flowing seawater — avoid tin or nickel plating that would break the film, and shot blast only with non-ferrous media to prevent iron contamination.
Surface treatments FabDigit runs on copper alloy parts — pick them in the quote configurator or call them out on the drawing. Each links to its datasheet in the surface-finish library (thickness, specs, call-out, material verdicts).

What is C96200 used for?
C96200 is typically used for seawater valves, pump bodies, marine fittings and heat exchanger heads. In short: baseline cast seawater alloy; good biofouling resistance; widely stocked cast Cu-Ni.
What is the yield strength of C96200?
C96200 has a typical yield strength of 179 MPa (26 ksi) and a tensile strength of 317 MPa (46 ksi) — weaker than 59% of copper alloy grades. Strength varies by condition: see the 5 listed tempers.
Is C96200 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 67% of copper alloy grades). Gummy, work-hardening chip — use sharp positive-rake carbide, heavy positive feed, rigid setup and copious coolant; do not dwell or the surface hardens.
Can C96200 be welded?
Yes — weldability is rated very good (75/100). Readily GTAW/GMAW welded with 65/30 CuNi (ERCuNi) filler; keep the weld zone clean and oxide/oil free, use low heat input, no preheat and never weld over sulfide-contaminated surfaces.

What is the maximum service temperature of C96200?
C96200 is rated for continuous use to about 315°C (599 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
