How do you make cupronickel?

Answer 1

Cupronickel has a natural resistance to corrosion in seawater, so it is often used in pipes carrying seawater to fire mains, cabled tubed for hydraulic lines, boat hardware, and underwater Fencing. The copper nickel alloy can also be found in jewelry and automobile parts.

Answer 2

The addition of nickel to copper improves strength and corrosion resistance but good ductility is retained. Copper-nickel alloys have excellent resistance to marine corrosion and biofouling.

The two main alloys are 90/10 and 70/30. The 70/30 is stronger and has greater resistance to sea water flow; but the 90/10 will provide good service for most applications and being less expensive tends to be more widely used. Both alloys contain small but important additions of iron and manganese which have been chosen to provide the best combination of resistance to flowing sea water and to overall corrosion.

Copper-nickel alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, high inherent resistance to biofouling and good fabricability. They have provided reliable service for several decades whilst offering effective solutions to todays technological challenges.

Applications

• Sea water pipework
• Offshore fire water systems
• Heat exchangers and condensers
• Sheathing of legs and risers on offshore platforms and boat hulls
• Hydraulic lines
• Fish cages for aquaculture
• Desalination units.

Answer 3

Cupronickel is typically made by combining copper and nickel in varying proportions, depending on the desired properties. The metals are usually melted together and then formed into the desired shape through processes like casting or rolling. Other elements like iron and manganese may also be added to further enhance specific characteristics of the alloy.

Answer 4

cupronickel is made of two metals called copper and nickel therefore it is an alloy
