High-Performance and Low-Cost Product
The essence of this structure lies in the firm combination of the three layers through metallurgical methods (such as explosive cladding and rolling cladding), achieving a performance of:
- Function: Provides excellent corrosion resistance and biocompatibility.
- Resists seawater, acidic environments, and chloride ion corrosion.
- Low density reduces overall weight; aesthetically pleasing surface finish.
- Function: Offers superior electrical and thermal conductivity; serves as a functional transition and buffer layer.
- Electrical/Thermal Bridge: Acts as the primary channel for current or heat in high-conductivity scenarios.
- Buffer & Bonding Layer: Copper has better compatibility with both titanium and steel, effectively alleviating thermal stress, enhancing bonding strength, and improving production feasibility.
- Function: Provides the main structural strength, rigidity, and toughness; significantly reduces costs.
- High mechanical strength and good processability (welding and machining).
- Cost-effective base material for large-scale applications.
Summary of Comprehensive Performance
"External Corrosion Resistance + Medium-High Conductivity + Internal High Strength": The surface is corrosion-resistant, the middle layer is highly efficient for electrical and heat transfer, and the inner layer is strong and load-bearing.
Excellent Electrochemical Compatibility: In applications such as cathodic protection, the potential sequence of titanium and copper can be carefully designed to achieve specific functions.
Good Thermal Expansion Matching: The copper transition layer reduces the stress caused by the difference in thermal expansion and contraction between the titanium and steel layers.
High Cost Performance: While ensuring high surface performance, using inexpensive steel as the base material is far less costly than using all-titanium or thick-copper materials.
Main Purposes and Application Fields
Special electrolytic electrodes and anode baskets used in the electrolysis of corrosive media (such as chlorine-containing environments). The titanium layer resists corrosion, the copper layer ensures uniform current distribution, and the steel layer serves as a structural framework. Also used as conductive structural components in highly corrosive environments.
Hybrid grounding and lightning protection systems for ships. The titanium layer resists seawater corrosion, the copper layer provides a low-resistance grounding path, and the steel layer offers structural support. Also used in cathodic protection systems as auxiliary anodes or special connectors requiring both conductivity and corrosion resistance.
Integrated conductive and structural components for key parts of nuclear power plants, such as control rod drive mechanisms or measurement instrument penetration assemblies. Titanium resists high-temperature and high-pressure primary circuit water; copper enables precise, low-loss signal and current transmission; steel withstands mechanical loads and is weldable to the main structure.
Special parts requiring lightweight, high strength, high conductivity, and environmental corrosion resistance. Applications include special grounding, electromagnetic shielding, or conductive structural units in spacecraft or high-performance aircraft. The copper layer provides electromagnetic pulse (EMP) protection capability.
Vacuum chambers or beam components in particle accelerators and synchrotron radiation sources. The titanium layer facilitates achieving ultra-high vacuum (low outgassing rate); the copper layer is used for cooling or transmitting high-frequency currents; the steel layer provides the main structural framework. The copper layer also effectively dissipates internal heat.
