Application Field Analysis
Double-layer metal clad bar material mainly of titanium clad copper is not only ensure material superior conductivity, and with a strong surface corrosion resistance. Widely used in strong corrosion condition of conductive body, such as electrochemical, electroplating, electrolysis, hydrometallurgy, PCB, electric chemical industry, water treatment, ocean engineering, etc.
· Electrolytic industry:
· Cathode roll: Used for producing electrolytic copper foil (a key raw material for lithium batteries and printed circuit boards), the titanium layer comes into contact with the corrosive electrolyte, and the copper layer provides high conductivity and thermal conductivity, being 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, used for corrosion prevention of facilities such as offshore platforms and pipelines, the titanium layer is resistant to seawater corrosion, and the copper layer enhances the efficiency of current distribution.
· High-performance electronic devices:
· Require contacts, connectors or heat dissipation substrates (such as power semiconductor modules) that are highly conductive but 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 a titanium layer prevents high-temperature oxidation or adhesion.
· 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).
· Chemical equipment:
· Reactor linings, agitators, etc., used in situations where both corrosion resistance and rapid heat conduction are required.
· Hydrogen fuel cell:
· Bipolar plates or related components, the titanium layer is resistant to the corrosive environment inside the fuel cell, and the copper layer ensures high conductivity.
· Nuclear industry:
· Some nuclear reactors require materials that are resistant to radiation, corrosion-resistant, and have good thermal conductivity.
· Decoration and Architecture:
· The surface is in titanium, with its color and durability. The interior is made of copper, providing strength and weight reduction, suitable for high-end decoration or architectural components.
· Medical Equipment:
· It combines the biocompatibility of titanium and the antibacterial property of copper, suitable for special medical devices or implantable equipment (requiring strict verification of biocompatibility).
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.
