In the past, true silver coins were debased with cupronickel. Despite high copper content, cupronickel is dark bronze in colour when in storage, but is a light copper colour when polished. Thermocouples and resistors whose resistance is stable across changes in temperature contain the 55% copper-45% nickel alloy constantan.
