MMO Wire Anode Introduction
MMO Wire Anode is a high-performance anode used in various cathodic protection applications. It is designed to provide long-lasting protection against corrosion in diverse environments. MMO titanium wire anode is made of titanium wire with a mixed metal oxide (MMO) coating. The MMO coating enhances the anode's corrosion resistance and increases its current efficiency. The coating thickness and surface area can be customized according to specific project requirements. The anode's characteristics include uniform current distribution, high efficiency, and outstanding durability.The MMO-coated titanium wire anode exhibits an exceptionally low consumption rate. The anode's operational lifespan depends on the current used for a specific application. During its service life, the size of the titanium wire anode remains almost unchanged. The inherent elasticity and stability of titanium give the wire anode considerable installation flexibility. The titanium wire is not affected by surge currents and can withstand higher current overloads during initial polarization without damaging the anode.
- Exceptional Corrosion Resistance: The MMO Wire Anode exhibits an unparalleled ability to shield against corrosion. Its distinctive design and superior materials render it highly resistant to the detrimental impacts of rust and degradation.
- Optimized Current Efficiency: This system is meticulously engineered to deliver an elevated level of current efficiency, ensuring that it adeptly and resourcefully combats the corrosion of metal structures, such as pipelines and water heaters.
- Even Current Dispersal: Among the foremost advantages of this cathodic protection system is its capability to uniformly disperse protective current across the structure’s surface, thwarting localized corrosion and ensuring comprehensive coverage.
- Tailored Coating Thickness and Surface Area: This system provides adaptability concerning coating thickness and surface area. It can be customized to suit the specific requirements of diverse applications, ensuring a precise and efficient solution.
- Economical Resolution: The MMO Wire Anode not only excels in effectiveness but also proves cost-efficient. Its capacity to extend the lifespan of structures and reduce the necessity for frequent maintenance renders it an economically sound choice.
- Minimal Long-Term Maintenance Expenditure: By substantially diminishing the maintenance demands of safeguarded structures, this cathodic protection system aids in minimizing long-term maintenance costs, ultimately conserving both time and resources.
- Robust and Enduring: The MMO Wire Anode is constructed for long-lasting performance. Its sturdy build and utilization of top-quality materials guarantee its sustained effectiveness over an extended duration, offering prolonged safeguarding against corrosion.

Applications
MMO flexible anode
It can be combined with cables to form an MMO flexible anode, well-suited for pipeline, storage tank floors and industrial infrastructures, etc. This unique coating of crystalline, electrically conductive noble metal oxide activates the titanium wire, allowing it to function effectively as an anode.
Pipeline
This MMO wire anode is produced by applying a multi-layer noble metal oxide catalyst to a high-tensile solid titanium wire substrate that conforms to ASTM B338 GR1 standards. Our MMO wire anode can be connected to a feed cable at one end or piggybacked to create a continuous anode suitable for installing beneath storage tanks or providing uninterrupted protection for pipelines.
Water heater liner
MMO wire anode is also effective for safeguarding the internal surfaces of water heaters. Their flexible shape ensures even current distribution, which is particularly valuable in areas where water levels can vary significantly.
