China Double-Layer Metal Composite Bar Material - Titanium, Zirconium, Copper Suppliers & Factory

Application Field Analysis

Double-layer metal clad bar material — mainly titanium clad copper — not only ensures superior conductivity, but also provides strong surface corrosion resistance. Widely used in high-corrosion conductive environments such as electrochemical processing, electroplating, electrolysis, hydrometallurgy, PCB manufacturing, electrochemical industry, water treatment, ocean engineering, and more.

• ⚡ Electrochemistry and Corrosion Environment Electrode
  · 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, and the copper layer provides high conductivity and thermal conductivity — one of the most significant applications of titanium-coated copper at present.
  · 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, and the copper layer enhances current distribution efficiency.
• 🔌 Special Conductive / Thermal Components
  · High-performance electronic devices:
  · Contacts, connectors, or heat dissipation substrates (such as power semiconductor modules) requiring high conductivity with resistance to local corrosion.
  · Vacuum equipment components requiring both conductivity and corrosion resistance.
  · Welding and high-temperature tools:
  · Resistance welding electrodes, electrical discharge machining electrodes, etc. Copper provides excellent conductivity, and the titanium layer prevents high-temperature oxidation or adhesion.
• 🌊 Marine and Chemical Equipment
  · Ship and seawater systems:
  · Seawater coolers, heat exchanger tubesheets, etc. The titanium layer resists seawater corrosion, while the copper layer enhances heat conductivity and reduces costs (compared to all-titanium).
  · Chemical equipment:
  · Reactor linings, agitators, etc., used where both corrosion resistance and rapid heat conduction are required.
• 🔬 New Energy and High Technology Fields
  · Hydrogen fuel cell:
  · Bipolar plates or related components. The titanium layer resists the corrosive internal environment of the fuel cell, and the copper layer ensures high conductivity.
  · Nuclear industry:
  · Some nuclear reactors require materials that are radiation-resistant, corrosion-resistant, and thermally conductive.
• 🏗️ Other Special Applications
  · Decoration and Architecture:
  · The titanium surface provides color 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 property of copper, suitable for special medical devices or implantable equipment (requiring strict verification of biocompatibility).
