China Suppliers Factory for Double-layer Metal Composite Bars - Titanium, Copper, Zirconium, Stainless Steel

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 highly corrosive conductive environments such as electrochemical, electroplating, electrolysis, hydrometallurgy, PCB, 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, while the copper layer provides high conductivity and thermal conductivity — one of the most significant applications of titanium-coated copper.
  · 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 (e.g., power semiconductor modules) requiring high conductivity with 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, and the titanium layer prevents high-temperature oxidation or adhesion.
• Marine and Chemical Equipment
  Ship and seawater systems:
  · Used for manufacturing 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 solutions.
  
  Chemical equipment:
  · Reactor linings, agitators, etc., used in situations requiring both corrosion resistance and rapid heat conduction.
• New Energy and High Technology Fields
  Hydrogen fuel cell:
  · Bipolar plates or related components. The titanium layer resists the corrosive environment inside the fuel cell, and the copper layer ensures high conductivity.
  
  Nuclear industry:
  · Some nuclear reactors require materials that are radiation-resistant, corrosion-resistant, and have good thermal conductivity.
• Other Special Applications
  Decoration and Architecture:
  · Surface in titanium for its color and durability; interior made of copper for 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 biocompatibility verification).
