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 "1 + 1 + 1 > 3".
Outer Layer — Titanium (Ti)
Function: Provides excellent corrosion resistance and biocompatibility.
Performance: Resists seawater, acidic environments, and chloride ion corrosion; low density reduces weight; aesthetically pleasing surface.
Middle Layer — Copper (Cu)
Function: Superior electrical and thermal conductivity; serves as a functional transition and buffer layer.
Performance: Acts as an electrical/thermal bridge; alleviates thermal stress between titanium and steel; enhances bonding strength and production feasibility.
Inner Layer — Steel (Stainless / Carbon)
Function: Provides main structural strength, rigidity, and toughness; significantly reduces costs.
Performance: High mechanical strength, good processability (welding, machining), and cost-effective base material.
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 conduction and heat transfer, and the inner layer is strong and capable of bearing loads.
- 🔵 Excellent electrochemical compatibility: In certain applications (such as cathodic protection), the potential sequence positions of titanium and copper can be carefully designed to achieve specific functions.
- 🔵 Good thermal expansion matching: Through the transition of the copper layer, the stress caused by the difference in thermal expansion and contraction between the titanium layer and the steel layer is reduced.
- 🔵 High cost performance: While ensuring high surface performance, using inexpensive steel as the base material is much less costly than using all-titanium or thick copper materials.
Ti/Cu/Steel clad material is designed to meet extreme or special multi-functional requirements, and is mainly applied in the following fields:
High-End Chemical & Electrochemical Industries
Special electrolytic electrodes and anode baskets. Used in the electrolysis of corrosive media (e.g., chlorine-containing environments); the titanium layer resists corrosion, the copper layer ensures uniform current distribution, and the steel layer serves as a framework. Also used as conductive structural components in highly corrosive environments.
Marine Engineering & Shipbuilding
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.
Power & Energy Sector (Nuclear Power)
Integrated conductive/structural components for key parts of nuclear power plants — such as control rod drive mechanisms or measurement instrument penetration assemblies — requiring resistance to high-temperature and high-pressure water (Ti), precise signal or current transmission (Cu), and the ability to withstand mechanical loads (Steel).
Aerospace & Defense
Special parts requiring lightweight, high strength, high conductivity, and environmental corrosion resistance. Used in special grounding, electromagnetic shielding, or conductive structural units in spacecraft or high-performance aircraft. The copper layer provides electromagnetic pulse protection capability.
Scientific Research Equipment
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, and the steel layer provides the main structure. The copper layer effectively dissipates internal heat.
