CuNi44 Copper Nickel Alloy For Sea Water System Components Resistant Of Corrosion
Description :
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.

Application :
- 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 plants.
