Application Field Analysis

• ⚡ 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 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, 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) that are highly conductive yet resistant to local corrosion.

  · 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 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 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 possess good thermal conductivity.

• 🏗️ Other Special Applications

  −

  Decoration and Architecture:

  · The surface is titanium, offering distinctive color and durability. The interior is copper, providing 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).
