Morphology

cupronickel = copper + nickel (transparent) = cupro + nickel

The word is a straightforward combination referring to an alloy of copper and nickel, which learners can infer if they know the two metals.

Etymology

Cupronickel combines cupr(o)-, from Latin 'cuprum' meaning 'copper' (think English copper), and nickel, the name of the other metal. So cupronickel means a mix of 'copper' and 'nickel', which is why it is used for coins and for ship parts because it resists salt water and does not rust easily.
