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.
Typical applications for Cu-Ni 90/10 Pipes & Tubes include marine engineering, shipbuilding, desalination, offshore platforms, heat exchangers, condensers, seawater piping, power generation and general engineering.
Key Features of Cu-Ni 90/10
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.
