Cupreous Metal (Copper, Bronze, Brass) Conservation

CUPREOUS METAL CORROSION The term 'cupreous' is used to designate all metals that consist of copper or alloys that are predominantly copper, such as bronze (an alloy of copper and tin) and brass (an alloy of copper, zinc, and often lead). The term does not imply a valence state as does cupric-divalent copper or cuprous-monovalent copper.
