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 "1 + 1 + 1 > 3".
- Resists seawater, acidic environments, and chloride ion corrosion
- Low density reduces overall weight
- Aesthetically pleasing surface finish
- Acts as primary channel for current or heat in high-conductivity scenarios
- Alleviates thermal stress between titanium and steel layers
- Enhances bonding strength and improves production feasibility
- High mechanical strength and good toughness
- Good processability (welding and machining)
- Cost-effective base material significantly reduces overall cost
- ✦ "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 significantly 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.
Main Purposes and Application Fields
Ti/Cu/Steel clad material is designed to meet extreme or special multi-functional requirements, and is mainly applied in the following industries:
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 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/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 in the primary circuit, precise low-loss signal/current transmission, and the ability to withstand mechanical loads.
Special parts requiring lightweight, high strength, high conductivity, and resistance to environmental corrosion — such as special grounding, electromagnetic shielding, or conductive structural units in spacecraft or high-performance aircraft. The copper layer provides electromagnetic pulse 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 and effectively dissipates internal heat, while the steel layer provides the main structural support.
