Premium Quality Titanium Cathodes from China Suppliers and Factory - 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
-
Q1 What makes titanium cathode plates superior to stainless steel cathode plates in electrolytic processes?Titanium cathode plates offer significantly better corrosion resistance than stainless steel, especially in chloride ion and acidic electrolyte environments such as copper sulfate and zinc chloride solutions. The naturally forming TiO₂ oxide film on titanium's surface provides long-term stability, whereas stainless steel may suffer from pitting or crevice corrosion under the same conditions. Additionally, titanium's lower density (57% of steel) makes it easier to handle and install while maintaining comparable mechanical strength.
-
Q2 What coating materials are commonly applied to titanium cathodes, and what are their functions?The most common coating materials are ruthenium-iridium (Ru-Ir) oxide and platinum (Pt). These coatings serve dual purposes: they significantly enhance the electrical conductivity of the titanium substrate by reducing resistivity, and they provide catalytic activity that lowers the overpotential for metal deposition. This results in reduced cell voltage, improved current efficiency, and overall energy savings during electrolysis operations.
-
Q3 How long is the typical service life of a titanium cathode plate, and what factors affect it?Under normal operating conditions, titanium cathode plates typically have a service life of 5 to 10 years or more. Key factors that influence longevity include the quality and thickness of the surface coating, the concentration and temperature of the electrolyte, current density, and the frequency of maintenance and cleaning. Proper surface pretreatment—such as sandblasting and activation—before coating application also plays a critical role in extending service life by improving coating adhesion.
-
Q4 Can titanium cathode plates be used in both acidic and alkaline electrolyte environments?Yes. Titanium cathode plates demonstrate excellent performance across a wide range of chemical environments. In acidic systems—such as sulfate or chloride electrolytes used in copper, zinc, nickel, and cobalt refining—they resist corrosion effectively. In alkaline environments, such as the high-temperature, high-concentration caustic soda solutions found in chlor-alkali industry electrolytic cells, titanium cathode plates also perform reliably as components of the cathode chamber. The specific coating selected may vary depending on the application environment.
-
Q5 How do titanium cathode plates contribute to environmental sustainability and green manufacturing?Titanium cathode plates support green manufacturing in several ways. Their extended service life (5–10+ years) significantly reduces the frequency of replacements, thereby lowering both material consumption and maintenance costs. Titanium is a fully recyclable material, and the thin noble metal coatings (Ru-Ir or Pt) require only minimal quantities of precious metals. Furthermore, the energy-saving properties of coated titanium electrodes—through reduced cell voltage and improved current efficiency—directly contribute to lower electricity consumption and a reduced carbon footprint in industrial electrolysis operations.
-
Q6 What are the emerging application areas for titanium cathode plates beyond traditional hydrometallurgy?Beyond traditional hydrometallurgy, titanium cathode plates are increasingly being adopted in several growing sectors. In the new energy field, they serve as cathode carriers for electrolytic manganese dioxide used in lithium battery precursors, and as electrodes in water electrolysis systems for green hydrogen production. In environmental engineering, they are applied in electrocoagulation and electro-Fenton processes for treating heavy metal-containing industrial wastewater. The electroplating industry also uses them for precious metal plating applications such as gold and platinum plating, where uniform current distribution is critical.
