Core Functions of Each Layer of Materials and the Comprehensive Performance after Composite
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:
🔵 Outer Layer — Titanium (Ti)
- Provides excellent corrosion resistance and biocompatibility
- Resists seawater, acidic environments, and chloride ion corrosion
- Low density reduces overall weight
- Aesthetically pleasing surface finish
🟠 Middle Layer — Copper (Cu)
- Superior electrical and thermal conductivity
- Acts as primary channel for current or heat transfer
- Buffer and bonding layer between Ti and steel
- Alleviates thermal stress and enhances bonding strength
⚫ Inner Layer — Steel (Stainless / Carbon)
- Provides main structural strength, rigidity, and toughness
- High mechanical strength and good processability
- Supports welding and machining operations
- Significantly reduces overall material 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 reduced.
- 💰 High cost performance: While ensuring high performance on the surface, 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 always aimed at meeting extreme or special multi-functional requirements, mainly applied in the following key industries:
🧪 Chemical & Electrochemical Industries
Used for special electrolytic electrodes and anode baskets in 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 applied as conductive structural components in highly corrosive environments.
⚓ Marine Engineering & Shipbuilding
Ideal for 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 (Nuclear Power)
Integrated conductive/structural components for key parts of nuclear power plants. Control rod drive mechanisms or measurement instrument penetration assemblies benefit from titanium's resistance to high-temperature and high-pressure water, copper's precise low-loss signal/current transmission, and steel's ability to withstand mechanical loads and be welded to the main structure.
🚀 Aerospace & Defense
Designed for special parts requiring lightweight, high strength, high conductivity, and environmental corrosion resistance. Applied 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
Used in 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 generated during operation.
