Titanium Clad Copper
Product Description
Titanium-copper composite material (also known as titanium-clad copper) achieves atomic-level tight bonding between commercial pure titanium and high-conductivity copper through advanced metallurgical processes such as explosive bonding, roll bonding, or explosive-roll bonding. This bimetallic composite not only retains the excellent corrosion resistance of titanium but also possesses the superior electrical and thermal conductivity of copper, along with reliable structural strength. It can effectively replace pure titanium, pure copper, and precious metal alloys, easily handling complex working conditions such as strong corrosion, high current, and high temperature.
Features
1. Excellent Dual Advantages of Corrosion Resistance and Conductivity
- Corrosion-Resistant Layer (Titanium): The surface pure titanium layer can resist various strong corrosive media, such as seawater, chlor-alkali solutions, acids, alkalis, and salt spray. In electrochemical and hydrometallurgical environments, its service life is far longer than that of pure copper components, up to more than 10 times.
- Conductive Core (Copper): The internal high-conductivity copper layer has a conductivity of over 90% IACS, and the overall electrical conductivity can reach 60%-80% of pure copper, which is much higher than that of pure titanium (only 2% IACS), effectively reducing voltage loss.
- Thermal Conductivity: The thermal conductivity is as high as 54 W/m ·K, three times that of titanium-steel composite plates, which can perfectly meet the needs of high heat load dissipation.
2. High-Strength Metallurgical Bonding
- The interface shear strength is ≥85MPa, far exceeding the requirement of ≥40MPa specified in the national standard GB13238, and some specifications can reach more than 200MPa.
- It can easily handle secondary processing such as bending, stamping, drilling, and welding, and will not delaminate or crack even under long-term thermal cycling conditions.
3. Lightweight and Cost-Effective
- Its density is only 60% of pure copper, reducing weight by 40%, which can significantly lower transportation and installation costs, and the weight burden of components.
- Compared with pure titanium, its electrical and thermal conductivity is increased by more than 50%; compared with pure copper, its corrosion resistance life is greatly extended, and the comprehensive use cost can be reduced by 30%-60%.
4. Excellent Processing Adaptability
According to customers' drawing requirements, it can complete customized processing such as cutting, drilling, bending, assembly welding, and forming, meeting the precision production needs of various electrodes, busbars, and structural components.
Applications
1. New Energy & Power Batteries

2. Electrolysis, Electroplating & Hydrometallurgy
Core Application Scenarios: In chlor-alkali chemical production, it can be used as insoluble anodes, cathodes, and conductive beams of electrolytic cells. Immersed in high-concentration acid-alkali electrolytes for a long time, it can resist corrosion from chlorine gas, sodium hydroxide, and other strong corrosive media, reducing electrode shedding and replacement frequency. In the electroplating industry (galvanizing, copper plating, nickel plating), it serves as an electroplating tank electrode to ensure stable current transmission and improve coating uniformity. In non-ferrous metal smelting (copper, zinc, nickel, cobalt), it acts as a conductive component of electrolytic cells, adapting to high-temperature and strong-corrosion smelting environments and extending equipment maintenance cycles.

Core Application Scenarios: In coastal substations and cross-sea power transmission projects, it is used as busbars, cable joints, and photovoltaic busbars, which can resist corrosion from marine salt spray and humid air, avoid conductive loss caused by oxidation and rust of traditional copper materials, and have a service life of more than 30 years. In seawater desalination projects, it is used as a conductive and corrosion-resistant component of heat exchangers and condensers, which not only adapts to the strong corrosion environment of seawater but also improves desalination efficiency with its excellent thermal conductivity. On ships and marine platforms, it serves as a conductive connector for electrical systems, resisting seawater immersion and salt spray corrosion to ensure stable operation of equipment.

The copper layer provides low-resistance electrical conductivity to ensure accurate signal transmission of medical equipment. In surgical equipment such as high-frequency electrosurgical units, it serves as electrode components, with both corrosion resistance and conductive stability, which can withstand high temperatures during surgery and disinfection environments, avoiding electrode corrosion affecting surgical results.
