Product Introduction
Titanium-copper cathode rods (titanium-clad copper cathode rods) are bimetallic composite conductive components specifically designed for highly corrosive electrochemical conditions. They feature a highly conductive pure copper core and a corrosion-resistant pure titanium outer layer, manufactured through metallurgical-grade bonding processes such as explosive welding and hot-rolling diffusion composite. Unlike traditional pure copper cathode rods, which are prone to corrosion, high losses, and electrolyte contamination, titanium-clad copper cathode rods isolate the copper core from corrosive electrolytes via the titanium outer layer, significantly extending service life, preventing copper ion precipitation and contamination, and maintaining a consistently low contact resistance. These products are widely used in non-ferrous metal electrowinning and electrolytic refining, acid electroplating, electrolytic copper foil production, chlor-alkali industries, and heavy metal wastewater recovery, serving as a core conductive material for reducing energy consumption and maintenance costs in electrolytic production lines.

Product Features and Applications
Product Advantages
Bimetallic synergy, corrosion resistance and conductivity in one: The inner high-purity T2 copper core ensures high current and low loss transmission, while the outer TA1/TA2 titanium layer provides comprehensive corrosion resistance protection, solving the industry pain points of pure copper rods being not corrosion resistant and pure titanium rods having low conductivity. A single rod meets the dual requirements of conductivity and corrosion resistance.
Metallurgical-grade bonding with stable long-term performance: The atomic-level metallurgical bonding of titanium and copper is achieved by explosive composite or hot rolling diffusion process, resulting in high interface bonding strength, no risk of increased contact resistance or delamination, low temperature rise and stable energy consumption under long-term high current operation, avoiding the problem of soaring contact resistance in traditional sleeve-type structures.
Ultra-long service life and lower total life cycle cost: The titanium layer has strong chemical inertness and excellent corrosion resistance in acidic electrolytes and chloride ion systems. Its service life is more than 10 times that of pure copper cathode rods, which greatly reduces the frequency of downtime for rod replacement, reduces labor, material and production downtime losses, and has significant overall cost advantages throughout the entire life cycle.
No impurities are released, ensuring product purity: The titanium layer does not react chemically with the electrolyte, and no copper ions or impurity ions are released during the electrolysis process, which will not contaminate the bath system. It can stably ensure the purity and yield of the cathode metal and the electroplating layer, and is especially suitable for high-precision electrolysis and high-cleanliness electroplating scenarios.
High structural strength and simplified tank design: The composite rod has both excellent mechanical strength and rigidity, and can simultaneously bear the load-bearing support function of cathode hangers and electrode plates. No additional support structure is required, which simplifies the internal design of the tank and makes installation and maintenance more convenient.
Fully customizable with strong adaptability: Supports full customization of cross-sectional shape, size specifications, titanium layer thickness, and end structure. It can be equipped with welding titanium-copper transition joints, conductive copper rods, and hanging lugs, and can be fitted with insulating sleeves. The finished product is directly compatible with various standard and non-standard electrolytic/electroplating tanks.
Application Areas
Hydrometallurgical industry: Electrowinning and electrolytic refining cell cathode conductive beams and conductive rods for non-ferrous metals such as copper, nickel, cobalt, and zinc.
Electroplating industry: cathode hanger rods and tank side conductive busbars for acid copper plating, hard chrome plating, and anodizing production lines.
In the electrolytic copper foil industry: the cathode roller conductive shaft of the foil production machine and the cathode conductive beam of the electrolytic cell ensure uniform and impurity-free copper foil deposition.
Chlor-alkali chemical industry: Conductive components for ion-exchange membrane electrolyzers and diaphragm electrolyzers, suitable for salt water electrolysis corrosion conditions.
Environmental resources industry: Electrolytic treatment of wastewater containing heavy metals, cathode conductive components of electrolytic devices for precious metal recovery.

Professional Consultation Q&A
Q1: What are the core advantages of titanium-clad copper cathode rods compared to pure copper cathode rods?
A1: The core advantages are reflected in three dimensions: service life, maintenance costs, and product quality.
● Service life: The corrosion resistance of titanium layer is far superior to that of pure copper. Under acidic electrolysis conditions, its service life can be more than 10 times that of pure copper rod, greatly reducing the frequency of replacement.
● Maintenance costs: Corrosion of pure copper rods produces copper sludge and contaminates the bath solution, requiring frequent cleaning and maintenance; titanium-clad copper rods do not precipitate corrosion, have high bath solution stability, and reduce maintenance costs by more than 60%.
● Conductivity stability: After corrosion, the cross-section of pure copper rods decreases and the contact resistance increases, resulting in a continuous increase in energy consumption; titanium-clad copper rods maintain a stable cross-section and low contact resistance over a long period of time, with small fluctuations in energy consumption and significant long-term energy-saving effects.
Q2: What are the differences between explosive bonding and hot rolling bonding processes, and how should one choose between them?
A2: Both processes involve metallurgical-grade bonding; the core difference lies in the applicable scenarios and costs.
● Explosion-bonded composite: adaptable to large-diameter, large-section, and irregular-shaped cross-section rods, with high bonding strength, suitable for heavy-load and high-current wet metallurgical scenarios, and highly flexible for single-piece customization.
● Hot-rolled/hot-extruded composite: Suitable for small to medium diameter standard cross-section rods, offering high production efficiency, good batch consistency, and higher surface finish, ideal for bulk orders in electroplating and precision electrolysis. We will recommend the optimal process solution based on your size specifications, operating conditions, and purchase volume.
Q3: Will the contact resistance of the titanium-copper composite interface affect the conductivity?
A3: No. We use metallurgical-grade composite technology to achieve atomic-level bonding at the titanium-copper interface, resulting in contact resistance as low as micro-ohms, far lower than that of bolted connections and sleeve assemblies. Furthermore, the interface will not oxidize or delaminate under long-term operation, and the resistance remains stable. The overall conductivity fully meets the requirements of high-current industrial scenarios.
