Application Field Analysis
Double-layer metal clad bar material — mainly titanium clad copper — not only ensures superior conductivity but also delivers strong surface corrosion resistance. Widely used in high-corrosion conductive environments such as electrochemical processing, electroplating, electrolysis, hydrometallurgy, PCB manufacturing, electrochemical industry, water treatment, and ocean engineering.
· Cathode roll: Used for producing electrolytic copper foil (a key raw material for lithium batteries and printed circuit boards). The titanium layer contacts the corrosive electrolyte while the copper layer provides high conductivity and thermal conductivity — one of the most significant current applications.
· Other electrolytic electrodes: Used in the chlor-alkali industry and hydrometallurgy as insoluble anodes or special cathodes, balancing conductivity and corrosion resistance.
· Cathodic protection system: As anode bed material for corrosion prevention of offshore platforms and pipelines; the titanium layer resists seawater corrosion and the copper layer enhances current distribution efficiency.
· Welding and high-temperature tools: Resistance welding electrodes, electrical discharge machining electrodes, etc. Copper provides excellent conductivity and a titanium layer prevents high-temperature oxidation or adhesion.
· Chemical equipment: Reactor linings, agitators, etc., used where both corrosion resistance and rapid heat conduction are simultaneously required.
· Nuclear industry: Some nuclear reactors require materials that are radiation-resistant, corrosion-resistant, and have good thermal conductivity.
· Medical Equipment: Combines the biocompatibility of titanium and the antibacterial properties of copper, suitable for special medical devices or implantable equipment (requiring strict biocompatibility verification).
Double-Layer Metal Clad Bar Material — Conclusion
Double-layer metal composite materials are not merely a simple "1+1". Instead, through advanced composite technologies, they achieve functional integration and performance amplification — successfully resolving the key engineering challenge that a single metal cannot simultaneously meet the requirements of "surface corrosion resistance" and "high conductivity of the bulk". They are particularly suitable for high-end and demanding industrial environments.
Frequently Asked Questions
Double-layer metal clad bar material is a composite product consisting of two different metals bonded together through advanced metallurgical processes such as explosive welding, roll bonding, or diffusion bonding. For example, titanium-clad copper combines a corrosion-resistant titanium outer layer with a highly conductive copper core, delivering dual performance that neither material could achieve alone.
The substrate materials include Copper (T1, T2), Anaerobic Copper (TU1, TU2), and Aluminum. The clad materials include Titanium (Ti), Zirconium (Zr), Nickel (Ni), Tantalum (Tan), and Stainless Steel (304, 316L). Custom combinations can be produced to meet specific project requirements.
We supply rectangular bars (width 20–150 mm × thickness 6–30 mm), round bars (Φ 8–50 mm), square bars (10–30 mm), and silk/wire material (Φ 2.0–8.0 mm). The conventional clad layer thickness ranges from 1.0 to 2.5 mm. Custom specifications are available upon request.
Titanium-clad copper is preferred in electrochemical environments because the titanium outer layer provides outstanding resistance to aggressive acids, alkalis, and chloride-containing electrolytes, while the copper core delivers the high electrical and thermal conductivity required for efficient current distribution. This combination significantly reduces material costs compared to using solid titanium while maintaining performance.
Our double-layer metal composite bar materials are manufactured in accordance with the Chinese national standard GB/T 12769-2015. Products can also be produced to meet other international standards or customer-specified technical requirements upon request.
