Products Description
An MMO wire anode is a titanium wire coated with mixed metal oxide catalytic coating. It works as an impressed current anode in cathodic protection systems.
Compared with traditional consumable anodes, MMO titanium wire anodes offer stable electrochemical performance, low consumption rate, strong corrosion resistance, and long operating life when properly selected and used under suitable project conditions.
The performance of an MMO wire anode depends on several factors, including coating type, coating loading, titanium substrate quality, operating current density, installation environment, electrolyte or soil conditions, and required design life.
That is why we do not recommend choosing an MMO wire anode only by diameter or price. A reliable selection should be based on your actual cathodic protection system.
Ehisen supplies MMO titanium wire anodes for impressed current cathodic protection systems. Our MMO wire anodes are made with titanium substrate and mixed metal oxide catalytic coating, designed to provide stable current output, corrosion resistance, and long service life in demanding protection environments.

Products applications
The versatility of Mixed Metal Oxide (MMO) Wire Anodes in the cathodic protection industry makes them highly regarded. Their inherent design guarantees that they provide unmatched corrosion prevention in a variety of situations by combining titanium wires with a specific mixture of metal oxides. Examining their uses in greater detail:
Soil-based Cathodic Protection:
MMO Wire Anodes have become essential components of grounding systems. They are used to protect buried utilities, storage tanks, and other subterranean metallic infrastructures from the ubiquitous dangers of corrosion caused by soil. The operational life of these utilities is significantly extended by their efficiency in these conditions.
Concrete Constructions:
The internal rebar corrosion of concrete structures poses a significant danger to their structural stability. In these situations, MMO Wire Anodes are essential. They are skilled at keeping the reinforcing bars in concrete from corroding, guaranteeing the robustness and security of constructions like tunnels and bridges as well as skyscrapers and parking lots.
Freshwater Environments:
Although it may not seem harmful, freshwater can cause corrosion in metallic buildings that are submerged. MMO Wire Anodes are made specifically to combat this. They are frequently employed to keep constructions safe and operational for extended periods of time, such as piers, docks, water tanks, and freshwater pipelines.
Marine Structures:
Corrosion is more likely in the marine environment because of the saltwater and variety of microbiological activity. In this situation, MMO Wire Anodes show their worth by providing strong defense for underwater cables, ship hulls, jetties, and offshore drilling platforms.

5.Note: Other third-party quality inspection items can be carried out according to customer requirements.
Coating Options
Ir-Ta MMO Coating
Ir-Ta coating is commonly used for oxygen evolution environments and long-life cathodic protection systems.
It is suitable for:
●Soil environments
●Freshwater systems
●Low-chloride conditions
●Long design life applications
●Tank bottom protection
●Pipeline cathodic protection
●Reinforced concrete protection
Ir-Ta MMO coating offers good chemical stability and is often selected when the system requires long-term durability under oxygen evolution conditions.
Ru-Ir MMO Coating
Ru-Ir coating is commonly used for chloride-containing environments where chlorine evolution performance is important.
It is suitable for:
●Seawater environments
●Brackish water systems
●Marine structures
●High-chloride conditions
●Electrochlorination-related environments
●Special CP systems with chloride exposure
Ru-Ir MMO coating provides strong catalytic activity in chloride media. The final selection should be based on chloride concentration, current density, temperature, and expected design life.
Custom MMO Coating Design
For special cathodic protection projects, we can adjust the coating system according to your working conditions.
Please provide your environment, current output, design life, installation method, and project standard. Our technical team will help evaluate the suitable coating type and coating loading.
How to Choose the Right MMO Wire Anode
Choosing the correct MMO wire anode is not only about diameter. The right anode should match your project design and working environment.
You need to consider:
●Protected structure type
●Soil resistivity or water conductivity
●Chloride concentration
●Required current output
●Current density
●Design life
●Anode layout
●Installation method
●Backfill material
●Cable connection method
●Project standard
For example, a pipeline project in high-resistivity soil may need a different anode layout from a tank bottom project in sand backfill. A freshwater tank and a seawater structure may also require different MMO coating systems.
If you are not sure which type to choose, send us your project conditions. We will help recommend a suitable MMO wire anode solution.
Common Problems Caused by Wrong Anode Selection
Choosing the wrong MMO wire anode may lead to:
● Insufficient current output
● Uneven cathodic protection potential
● Higher circuit resistance
● Fast coating consumption
● Poor cable or joint performance
● Shorter-than-expected service life
● Higher maintenance cost
● Project delay or replacement risk
Most failures are not caused by titanium wire alone. They are often related to coating selection, current density design, installation layout, cable connection, backfill condition, and real operating environment.
That is why we recommend confirming project conditions before final quotation.
Quality Control
Quality control is important for MMO titanium wire anodes because coating quality directly affects current output and service life.
Our inspection process may include:
● Titanium substrate inspection
● Wire diameter inspection
● Surface pretreatment check
● Coating appearance inspection
● Coating adhesion test
● Coating loading or thickness control
● Electrical performance verification
● Accelerated life testing when required
● Packing inspection before shipment
For project orders, we can provide inspection documents according to customer requirements.
