Copper nickel tubing for fuel is a copper alloy tube that contains nickel and strengthening elements, such as iron and manganese. One of the important properties of cupronickel tubing is high-pressure resistance, which meets the strict pressure requirement of fuel (oil and gas) delivery tubing. Despite its high copper content, Copper nickel is silver in colour, due to nickel's high electronegativity causing copper's d-shell electron loss.
