Platinum is used on the surface as a primary anode material due to its excellent corrosion resistance under anodic conditions coupled with its ability to pass current in all electrolytes without forming an insulating film. The corrosion resistance of platinum manifests itself in its low consumption rate. Its major disadvantage is its high cost, thus making it clear that it is most desirable to use as little platinum as is necessary. In order to restrict the amount of platinum used and to maintain an anode of some structural integrity, it is necessary to use some type of substrate material.

Platinum-niobium wire anode is a composite made of a niobium base and plated platinum. Platinum-niobium wire anode has good corrosion resistance, great current density and very low consumption rate. Platinum-niobium wire anode is the best choice for use in the high resistivity containing Cl electrolyte solution.

Platinum-niobium wire anode has low consumption rate and long life, mainly used in the field of cathodic protection for offshore platforms, reinforced concrete, shipbuilding, steel piles, circulating pumps, condensers, piping, storage tanks, etc.
