In chemical plants and refineries, cupronickel alloys containing manganese and iron have found application in valves, pump bodies, rotating elements like impellers, heat exchanger components, and parts of distillation machines, stirrer equipment, presses and corrosion resistant pipelines.

What is the use of cupronickel?

Cupronickel is highly resistant to corrosion by salt water, and is therefore used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats.

What is cupronickel made of?

Cupronickel, any of an important group of alloys of copper and nickel; the alloy containing 25 percent nickel is used by many countries for coins. Because copper and nickel mix readily in the molten state, the useful range of alloys is not confined within any definite limits.
