MMO Titanium Ribbon Anode for Impressed Current Cathodic Protection (ICCP)
The MMO Titanium Ribbon Anode is engineered for Impressed Current Cathodic Protection (ICCP) systems, specifically designed for the bottom plates of above-ground storage tanks and reinforced concrete structures. Built on an ASTM B265 Grade 1 titanium substrate and coated with a mixed metal oxide (typically iridium-tantalum based), it provides a stable, low consumption rate and high current output density in aggressive environments.
Our in-house titanium mesh welding and thermal decomposition coating lines ensure consistent precious metal loading and uniform adhesion across every coil, minimizing project risks for corrosion engineers and contractors.
Key Features
Stable Electrochemical Performance: Low consumption rate (≤ 1 mg/A·yr) ensures long-term operational stability.
High Current Density: Operates efficiently at high current outputs without substrate passivation.
Dimensional Stability: Maintains structural integrity throughout its designed service life; does not distort under mechanical stress during installation.
Weldability: Designed for secure spot-welding to titanium conductor bars, forming low-resistance electrical connections.
Factory-Controlled Coating: Applied via controlled thermal decomposition, verified by accelerated lifetime testing (ALT).

Frequently Asked Questions
Q: What is the standard lifespan of your MMO titanium ribbon anode?
A: Standard designs offer 20 to 30 years of operating life. Lifespan is directly determined by the coating thickness (loading weight in g/m²) and operating current density specified for your project.
Q: What standards do your titanium substrates meet?
A: The titanium substrate strictly complies with ASTM B265 Grade 1 or Grade 2 specifications, ensuring low iron content and optimal purity for corrosion resistance.
Q: Can the ribbon be welded directly to titanium conductor bars?
A: Yes. The ribbon is designed for electrical connection via resistance spot-welding to titanium conductor bars. We also supply pre-welded grid assemblies to minimize field installation work.
Q: How do you test the durability of the coating before shipment?
A: We perform Accelerated Life Testing (ALT) in aggressive acid solutions on sample coupons from every production batch to verify that the coating lifespan meets design specifications.
Q: What is the recommended current output density in concrete structures?
A: For reinforced concrete applications, the typical maximum design current output density ranges up to 110 mA/m², depending on concrete resistivity and rebar surface area.
Q: What documents are provided with the shipment?
A: Every shipment includes a Mill Test Certificate (MTC) for the titanium substrate, coating thickness verification report, and a Certificate of Conformance (CoC).
