Cu-Ni 90/10 (C70600) is a copper-nickel alloy widely used for seawater piping because of its corrosion and biofouling resistance. Copper nickel (Cu-Ni) alloys such as 90/10 and 70/30 offer excellent resistance to seawater corrosion and biofouling, combined with good thermal conductivity and fabricability.

Available forms & variants

  • Seamless Pipes — The go-to choice for high-pressure and high-temperature lines.
  • ERW Pipes — Economical welded pipe for utility and process piping.
  • Welded / EFW Pipes — Fusion-welded construction for large-diameter runs.
  • Tubes — Round, square and rectangular tubes, plus U-bends for heat exchangers.

Performance highlights

  • Seawater Corrosion Resistance — Excellent performance in seawater and marine environments.
  • Biofouling Resistance — Natural resistance to marine biofouling.
  • Thermal Conductivity — Good heat-transfer properties for exchangers and condensers.
  • Easy Fabrication — Good formability and weldability.
