Premium Quality Titanium Cathodes from China Factory - Leading Suppliers of Titanium Clad Copper Hanger Bars and Plates
Product Features
-
🛡️ 1. Excellent Corrosion Resistance
Titanium exhibits outstanding corrosion resistance in oxidative media and chloride ion environments, and can withstand the long-term erosion of acidic electrolytes such as copper sulfate, nickel sulfate, and zinc chloride. A dense oxide film (TiO₂) forms easily on its surface, which is highly stable and has a long service life (typically over 5 to 10 years).
-
⚡ 2. Good Electrical Conductivity & Low Resistance
Titanium itself has a relatively high resistivity, but its conductivity can be significantly enhanced and the cell voltage reduced by applying special surface treatments, such as coating with noble metal oxide layers, thereby saving electrical energy. Common coating materials include ruthenium-iridium (Ru-Ir) and platinum (Pt), which possess both catalytic activity and stability.
-
🏗️ 3. High Strength & Lightweight
Titanium has a density of only 57% that of steel, yet its strength is close to that of common steel. It is easy to install and transport, and can withstand mechanical stress during the electrolysis process. It has good rigidity and is not prone to deformation under long-term current, ensuring the stability of the plate spacing.
-
🔬 4. Surface Characteristics Optimization
The surface can undergo treatments such as sandblasting and activation to enhance the adhesion of the coating, or be designed with specific patterns to facilitate gas release (such as hydrogen evolution during electrolysis). The coating can reduce the overpotential for metal deposition and increase current efficiency.
-
🌿 5. Environmental Protection & Economy
Long service life reduces replacement frequency and lowers maintenance costs. Titanium material is recyclable and requires less coating metal, meeting the requirements of green production.

Frequently Asked Questions
-
Q What is a titanium cathode plate and how does it work in electrolysis?A titanium cathode plate is an electrode component made from high-grade titanium substrate, often coated with noble metal oxides (such as ruthenium-iridium or platinum). During electrolysis, metal ions in the electrolyte solution are reduced and deposited onto the cathode surface. The titanium substrate provides structural stability, corrosion resistance, and long service life, while the coating enhances electrical conductivity and catalytic performance.
-
Q Why is titanium preferred over stainless steel for cathode plates in hydrometallurgy?Titanium offers superior corrosion resistance in acidic and chloride-rich environments compared to stainless steel. It naturally forms a stable TiO₂ oxide film that protects against chemical attack. Additionally, titanium is significantly lighter (density ~57% of steel) while maintaining comparable strength, making it easier to handle and install. Its longer service life (5–10+ years) also reduces overall operational costs.
-
Q What coating materials are commonly used on titanium cathode plates?The most common coating materials are ruthenium-iridium (Ru-Ir) oxide and platinum (Pt). These noble metal coatings provide excellent catalytic activity, reduce overpotential during metal deposition, and improve current efficiency. The choice of coating depends on the specific electrolytic application, operating temperature, and the chemical composition of the electrolyte.
-
Q How long is the typical service life of a titanium cathode plate?Under normal operating conditions, titanium cathode plates have a typical service life of 5 to 10 years or more. The actual lifespan depends on factors such as the concentration and type of electrolyte, operating temperature, current density, and the quality of the surface coating. Proper maintenance and periodic inspection can further extend the service life.
-
Q Can titanium cathode plates be used in hydrogen production through water electrolysis?Yes. Titanium cathode plates are increasingly used in water electrolysis systems for green hydrogen production. Their excellent corrosion resistance in alkaline and acidic electrolytes (such as PEM and alkaline electrolyzers), combined with high-performance coatings that reduce hydrogen evolution overpotential, make them ideal cathode carriers for efficient and durable hydrogen generation.
-
Q Are titanium cathode plates environmentally friendly and recyclable?Yes. Titanium is a highly recyclable material, and spent cathode plates can be reprocessed to recover both the titanium substrate and the precious metal coating, minimizing waste. Their long service life reduces replacement frequency and associated waste generation. These characteristics make titanium cathode plates a sustainable choice that aligns with green manufacturing and circular economy principles.
