CITIZEN introduced special purity Copper Anodes produced from virgin Copper cathode especially for Decorative, Rotogravure, Printed Circuitry, Electrical Ground Rod, Electroforming and many other functional plating applications.

CITIZEN (OF) is a high-purity copper with electrical conductivity of at least 100 % IACS. The maximum oxygen content is 10 ppm (0.001%) and the copper is resistant to hydrogen embrittlement. 

Manufacture
(OF) manufacturing starts with high-quality copper cathodes melted under strictly controlled conditions and cast in an inert atmosphere into cakes. During this process the copper is not allowed to come into contact with air. Intermediate or final annealing is done either in a reducing atmosphere or a vacuum. Properties
