Applications of Copper Nickel

Cupronickel (Copper-Nickel) includes nickel and nourishing and boosting elements like manganese and iron. It has significant characteristics comprising outstanding ductility, corrosion resilience, adequate tensile robustness, immanent macrofouling resistance, thermal conductivity, extension properties persuadable for heat exchangers and condensers and favourable antimicrobial touch aspects. Copper and nickel effortlessly alloy with one and another. They are tensile and promptly contrived and have a mere composition. Inspite of the excessive proportion of copper, cupronickel has a silver colour. It’s melting point 1170-1240 Degree Celsius and its density is 8.5 mg/m3.

Applications of Cupronickel

The major applications of cupronickel according the Sunflex Metals, the biggest manufacturer and supplier of Copper Nickel are heat exchangers and condensers, seawater piping and for aquatic applications mainly because of their resilience to seawater corrosion.


Cupronickel alloys such as 70Cu30Ni are extensively utilised in MED (multiple effect distillation) and MSF (multi-stage flash) due to their eminent thermal conductivity and corrosion resistance. In summation to the price deliberations, the possibility relies on corrosion situation in several elements of the plant.

MED plants

MED plants are categorised in two forms, one is MVD (mechanical vapour compression) and second and more frequently used is TCD (thermo-compression distillation). There can be various evaporator phases and a concluding heat dismissal segments. Cupronickel is the foremost option for tubes in the evaporator sections. Moreover, sometimes it is used in the heat recuperation exchanger that functions entirely dilated.

Offshore Oil and Gas

Cupronickel has applications on stages as well as FPSO’s (Floating Production Storage and Offloading Vessels) and is in seawater. It is used in structure and splash sector sheathing on onshore oil and gas zones as they have decreased amounts of macrofouling and can be instantly melded to steel.

Shipbuilding and Repair

Cupronickel was initially supplemented for condensers and seawater cooling and piping. It also used on commercial shipping. Moreover, it is used in hydraulic and pneumatic chiller systems, noble gas, fire-fighting, hygiene and bilge and ballast.

Power Generation

Nuclear and Fossil fuel power plants have ancillary cooling complex, excessive and intense pressure pre-heaters, turbine condensers, oil coolers, pipework and valves. The usage of cupronickel alloys is appropriate and befitting for this.

Cupronickel is used in coinage due to its electrical conductivity, corrosion resilience, ductility, permanence, antimicrobial features, and composure to inscribing.

Other uses

Due to its silver colour and rust-less glistening, cupronickel is used in:

  • Jewels and ornaments
  • Medical appliances
  • Automobile units
  • Cylinder cores
  • Silver-plated cutlery
  • Hulls of ships
  • Steel brake lines

Cupronickel heat exchangers and condensers

Cupronickel heat exchangers and condensers is an intense presentation appliance used in several industrial applications. Their purpose is transferring the heat in between two liquid flows. They are extremely persistent and variable. The existence of nickel provides resilience to higher pressure corrosion oxidation and crumbling. It supplies high thermal durability & firmness and adequate power in high-temperature conditions.

The heat exchanger tubes hold surpassing innate resilience to contriving and biofouling. The tempering of these heat condensers and exchangers is conducted at a temperature of 593-816 degree C and because of this it has the ability to function in cold and provides exceptional service.
