What Does Cupro Nickel Mean?

Cupronickel or copper-nickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. The copper content typically varies from 60 to 90 percent. Despite its high copper content, cupronickel is silver in colour.

What is cupro nickel used for?

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.

Is cupro nickel worth anything?

The value of the metal in both the cupronickel and nickel-plated steel coins is still less than their face value. HM Treasury and The Royal Mint will continue to ensure that there are enough coins, of the right denominations, to meet public demand.
