    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 high-corrosion conductive applications such as electrochemistry, 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 current applications.
      · 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 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 and local corrosion resistance.
      · Vacuum equipment components that must be both conductive and corrosion-resistant.

      Welding and High-Temperature Tools:
      · Resistance welding electrodes and electrical discharge machining electrodes — 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 — 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, and components where both corrosion resistance and rapid heat conduction are required simultaneously.
    • 🔋 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 have excellent thermal conductivity.
    • 🏛️ Other Special Applications +
      Decoration and Architecture:
      · Titanium surface for color and durability; copper interior for 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).

    Double-Layer Metal Clad Bar Material — Conclusion

    Double-layer metal composite materials are not merely a simple "1+1". Instead, through advanced composite technologies, they achieve functional integration and performance amplification, successfully resolving the key engineering challenge that a single metal cannot simultaneously meet the requirements of "surface corrosion resistance" and "high conductivity of the bulk". They are particularly suitable for high-end and demanding industrial environments.

    Frequently Asked Questions (FAQ)

    • Q What is double-layer metal clad bar material?
      Double-layer metal clad bar material is a composite product made by metallurgically bonding two different metals — such as titanium and copper — into a single bar. This structure combines the corrosion resistance of the outer layer (e.g., titanium) with the high electrical and thermal conductivity of the inner layer (e.g., copper), delivering performance that neither metal could achieve alone.
    • Q What substrate and clad material combinations are available?
      Common substrate materials include Copper (T1, T2), Anaerobic Copper (TU1, TU2), and Aluminum. Clad materials include Titanium (Ti), Zirconium (Zr), Nickel (Ni), Tantalum (Tan), and Stainless Steel (304, 316L). Custom combinations can be arranged based on specific application requirements.
    • Q What sizes and shapes are available for clad bar material?
      Available cross-section shapes include rectangular (width 20–150 mm × thickness 6–30 mm), circular (Φ 8–50 mm), square (10–30 mm), and wire/silk material (Φ 2.0–8.0 mm). The standard clad layer thickness ranges from 1.0 to 2.5 mm. All products can be customized to meet customer specifications.
    • Q What industries commonly use titanium-clad copper bar material?
      Titanium-clad copper bar material is widely used in electrochemistry, electrolysis, hydrometallurgy, PCB manufacturing, water treatment, marine engineering, hydrogen fuel cells, chemical processing equipment, and high-performance electronic components. Its combination of corrosion resistance and conductivity makes it ideal for demanding industrial environments.
