Premium Quality Titanium Cathodes from China Suppliers - Durable Titanium Clad Copper Hanger Bars & Plates Factory
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's conductivity can be significantly enhanced and 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, can withstand mechanical stress during the electrolysis process, 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
-
QWhat makes titanium cathode plates superior to other cathode materials in electrolytic processes?Titanium cathode plates offer a unique combination of excellent corrosion resistance, high strength-to-weight ratio, and long service life (typically 5–10+ years). Their surface can be coated with noble metal oxides such as ruthenium-iridium (Ru-Ir) or platinum (Pt) to significantly enhance electrical conductivity and catalytic performance, making them far more durable and efficient than conventional materials in aggressive electrolytic environments.
-
QHow long is the typical service life of a titanium cathode plate?Under normal operating conditions, titanium cathode plates typically last 5 to 10 years or more. The dense TiO₂ oxide film that naturally forms on the titanium surface provides exceptional stability and protection against acidic and chloride-rich electrolytes, significantly reducing the need for frequent replacement and lowering overall maintenance costs.
-
QWhat types of coatings are commonly applied to titanium cathode plates, 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 and provide catalytic activity that reduces overpotential for metal deposition. Surface pre-treatments such as sandblasting and chemical activation are also applied to improve coating adhesion and longevity.
-
QIn which industries are titanium cathode plates most widely used?Titanium cathode plates are widely used across multiple industries, including hydrometallurgy (copper, zinc, nickel, cobalt, and manganese electrolysis), the electroplating industry (precious metal plating such as gold and platinum), the chlor-alkali industry, electrochemical water treatment for environmental protection, and the preparation of new energy materials such as electrolytic manganese dioxide and hydrogen production via water electrolysis.
-
QAre titanium cathode plates an environmentally friendly choice for industrial electrolysis?Yes. Titanium cathode plates are considered an environmentally responsible option for several reasons: their long service life minimizes replacement frequency and waste generation; titanium is a fully recyclable material; and the coatings require only small amounts of noble metals, reducing resource consumption. These properties align well with the goals of green manufacturing and sustainable industrial production.
-
QCan titanium cathode plates be customized for specific electrolytic applications?Yes. Titanium cathode plates can be tailored to meet specific process requirements. Surface treatments, coating compositions, plate dimensions, and structural patterns (such as gas-release channel designs) can all be customized. This flexibility allows manufacturers to optimize current efficiency, minimize energy consumption, and ensure compatibility with a wide range of electrolyte systems and operating conditions.
