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.
