  • Electrical conductor, in particular suitable for use as an insoluble anode in electrowinning processes, and in electrochemical processes in general, and process for producing it
    Patent number: 5030520
    Abstract: An electrical conductor is particularly suitable for use as an insoluble anode in electrowinning processes, and is composed of an inner core of copper coated with an outer, thinner layer of a transition metal, preferably selected from among tantalum, titanium and niobium. The conductor is manufactured by a process including the steps of inserting a copper bar inside a relatively thin tube made of the selected transition metal, inserting the tube containing the copper bar inside a copper tube to obtain a three-metal structure, submitting the three-metal structure to a drawing process to produce a three metal wire, and dipping the three-metal wire in a solvent to remove the outer copper layer to produce a bimetallic wire.
