Titanium-clad copper is a composite material created primarily through explosive welding or rolling (with explosive welding being more common). It combines the excellent conductivity, cost-effectiveness, and formability of copper with the exceptional corrosion resistance of titanium.

Titanium-copper clad materials include titanium-copper rods, titanium-copper plates, and titanium-copper tubes. Among them, the titanium-copper clad rod is the most widely used.

Due to its outstanding conductivity and corrosion resistance, titanium-clad copper cathodes are widely used in electrochemical applications. The copper core ensures efficient conductivity, while the titanium cladding provides corrosion protection, making it suitable for various corrosive environments. In electroplating, titanium-copper cathodes extend equipment life and improve plating efficiency; in electrolysis and electrorefining, their durability excels in metal extraction and refining, particularly in copper, zinc, and nickel recovery. In chlor-alkali production, they resist chlorine corrosion, ensuring long-term use. Additionally, titanium-clad copper cathodes effectively remove heavy metals and pollutants in water and wastewater treatment, and in cathodic protection systems, they offer corrosion protection for pipelines and marine structures.
