CuNi44 Copper Nickel Alloy For Sea Water System Components
Resistant Of Corrosion
Copper Nickel is an alloy that can contain anywhere from 2% to 30%
nickel. This material has a very high corrosion-resistance and has
thermal stability. This material also exhibits a very high
tolerance to corrosion cracking under stress and oxidation in a
steam or moist air environment. Higher nickel content in this
material will have improved corrosion resistance in seawater, and
resistance to marine biological fouling. This material is typically
used in making electronic products, marine equipment, valves, pumps
and ship hulls.
- Shipbuilding and repair: Cupronickel alloys are used in seawater
cooling, bilge and ballast, sanitary, fire fighting, inert gas,
hydraulic and pneumatic chiller systems.
- Desalination plants: Cupronickel alloys are used in brine heaters,
heat rejection and recovery, and in evaporator tubing
- Offshore oil and gas platforms and processing and FPSO vessels:
Cupronickel alloys are used in systems and splash zone sheathings.
- Seawater system design: Cupronickel alloys are used in tubular heat
exchangers and condensers, piping and high pressure systems.
- Cupronickel is used in cryogenic applications. Its combination of
good ductility retention and thermal conductivity at very low
temperatures is advantageous for low-temperature processing and
storage equipment as well as for heat exchangers at cryogenic
