Application Field Analysis
Double-layer metal clad bar material — mainly titanium clad copper — not only ensures superior electrical conductivity but also provides strong surface corrosion resistance. It is widely used in highly corrosive conductive environments, including electrochemical processing, electroplating, electrolysis, hydrometallurgy, PCB manufacturing, electrochemical industry, water treatment, ocean engineering, and more.
Electrolytic Industry:
· Cathode Roll: Used for producing electrolytic copper foil (a key raw material for lithium batteries and printed circuit boards). The titanium layer contacts the corrosive electrolyte; the copper layer provides high conductivity and thermal conductivity — one of the most significant applications of titanium-coated copper today.
· Other Electrolytic Electrodes: Used in the chlor-alkali industry and hydrometallurgy as insoluble anodes or special cathodes, balancing conductivity and corrosion resistance.
· Cathodic Protection System: As an anode bed material for corrosion prevention of offshore platforms and pipelines. The titanium layer resists seawater corrosion; the copper layer enhances current distribution efficiency.
High-Performance Electronic Devices:
· Contacts, connectors, or heat dissipation substrates (e.g., power semiconductor modules) requiring high conductivity and local corrosion resistance.
· Some vacuum equipment requires components that are both conductive and corrosion-resistant.
Welding and High-Temperature Tools:
· Resistance welding electrodes, electrical discharge machining electrodes, etc. Copper provides excellent conductivity; the titanium layer prevents high-temperature oxidation or adhesion.
Ship and Seawater Systems:
· Seawater coolers, heat exchanger tubesheets, etc. The titanium layer resists seawater corrosion; the copper layer enhances heat conductivity and reduces costs compared to all-titanium components.
Chemical Equipment:
· Reactor linings, agitators, etc., used where both corrosion resistance and rapid heat conduction are required.
Hydrogen Fuel Cell:
· Bipolar plates or related components. The titanium layer resists the corrosive internal environment of the fuel cell; the copper layer ensures high conductivity.
Nuclear Industry:
· Some nuclear reactors require materials that are radiation-resistant, corrosion-resistant, and thermally conductive.
Decoration and Architecture:
· The titanium surface provides aesthetic appeal and durability; the copper interior offers strength and weight reduction, suitable for high-end decoration or architectural components.
Medical Equipment:
· Combines the biocompatibility of titanium and the antibacterial properties of copper, suitable for special medical devices or implantable equipment (requiring strict biocompatibility verification).
