Premium Quality Titanium Cathodes from China Suppliers - Factory Direct 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 and 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 makes titanium cathode plates superior to stainless steel cathodes in electrolytic processes? ▼Titanium cathode plates offer significantly better corrosion resistance in acidic and chloride-rich electrolytes compared to stainless steel. They form a stable TiO₂ oxide layer on their surface, which protects against long-term chemical erosion. Additionally, titanium is lighter (only 57% the density of steel) while maintaining comparable strength, making installation and handling much easier. Their service life typically exceeds 5–10 years, reducing overall maintenance costs.
-
Q What coating materials are commonly used on titanium cathode plates, and why? ▼The most common coating materials applied to titanium cathode plates are ruthenium-iridium (Ru-Ir) oxide mixtures and platinum (Pt). These noble metal oxide coatings serve dual purposes: they significantly enhance the electrical conductivity of the titanium substrate and provide excellent catalytic activity for electrochemical reactions. They also help reduce cell voltage and overpotential for metal deposition, thereby improving current efficiency and reducing energy consumption.
-
Q In which industries are titanium cathode plates most widely used? ▼Titanium cathode plates are most widely applied in hydrometallurgy (copper, zinc, nickel, cobalt, and manganese electrolysis), the electroplating industry (precious metal plating such as gold and platinum), the chlor-alkali industry (ion-exchange membrane electrolytic cells), electrochemical water treatment (electrocoagulation and electro-Fenton processes), and new energy material preparation (electrolytic manganese dioxide and hydrogen production via water electrolysis).
-
Q How does the surface treatment of titanium cathode plates affect their performance? ▼Surface treatments such as sandblasting and chemical activation play a critical role in improving the adhesion of the noble metal oxide coating to the titanium substrate, ensuring a longer-lasting and more uniform coating layer. Specific surface patterns or textures can also be engineered to promote efficient gas release during electrolysis (e.g., hydrogen evolution), which helps maintain consistent electrode performance and prevents gas bubble accumulation that could interfere with current distribution.
-
Q Are titanium cathode plates an environmentally friendly choice for industrial electrolysis? ▼Yes, titanium cathode plates are considered an environmentally responsible choice for several reasons. Their long service life (5–10+ years) significantly reduces the frequency of replacement, lowering waste generation and maintenance-related resource consumption. Titanium is a fully recyclable material, and the noble metal coatings used are applied in minimal quantities, reducing the demand for scarce resources. Their energy-saving properties through reduced cell voltage also contribute to lower carbon emissions in industrial operations, aligning with green manufacturing standards.
-
Q What is the expected service life of titanium cathode plates, and what factors affect their longevity? ▼Under normal operating conditions, titanium cathode plates typically have a service life of 5 to 10 years or more. Key factors that influence their longevity include the quality and thickness of the noble metal oxide coating, the concentration and temperature of the electrolyte, the operating current density, the frequency of maintenance and cleaning, and the precision of the surface treatment applied during manufacturing. Proper installation and adherence to recommended operating parameters can significantly extend the service life of the plates.
