Products Overview
Zhongxinbao Metal iridium–tantalum coated titanium anodes are widely used in electrochemical and electroplating systems due to their stable catalytic performance, low oxygen evolution overpotential, and excellent corrosion resistance under demanding operating conditions. The Ir–Ta MMO coating provides reliable performance while maintaining a lightweight and structurally stable titanium substrate.
Zhongxinbao Metal manufactures Ir–Ta coated titanium anodes in multiple configurations, including plates, meshes, rods, and custom-formed structures. Anode geometry and effective surface area are designed according to the customer's specific bath dimensions, operating current, electrolyte composition, and process requirements.
Based on defined service conditions, Zhongxinbao Metal can optimize the Ir–Ta coating composition and loading to achieve the required service life and operating stability. Anode size, shape, and coating thickness can be customized to match the customer's actual working conditions and expected lifespan.

Application & Features
product key technologies
Water treatment and disinfection system
It is applied to electrochemical disinfection, oxidation to remove pollutants, and online sterilization in municipal and industrial water treatment, and is suitable for chlorine-containing or strong oxidizing environments.
Electroplating and Surface Treatment
Used as an inert anode, it is suitable for processes such as nickel plating, copper plating, and gold plating. It provides uniform current distribution and controllable coating loss.
Why Choose us?
We offer a variety of services
Stable Coating System with Controllable Lifespan
The Ir-Ta composite coating design balances catalytic activity and corrosion resistance, maintaining low-loss operation under high current density and chlorine-containing conditions.
Clear Operating Boundaries and More Reliable Parameters
Provides clearly defined recommended current densities, media compatibility, and operating limitations, avoiding lifespan uncertainties caused by "overload use."
Good Consistency and Repeatability
Controlled coating thickness and sintering process result in minimal batch-to-batch voltage and performance fluctuations, suitable for long-term continuous operation systems.
Customized Support for Engineering Applications
Dimensions and coating schemes can be customized according to electrolyzer structure, current distribution, and media conditions, reducing system compatibility risks.
