Vale Nickel Plating Chips® are a disk like shaped, non-activated, 99.98 % high purity form of nickel anode material made from Vale's unique carbonyl refining process. The dissolution characteristics are similar to other non-activated nickel anodes and they will dissolve at 100 % anode efficiency in common nickel electroplating solutions that contain chlorides. Dissolution produces a small amount of metallic residues.
