Product Description

What Is MMO Disc Anode and How to Choose the Right One for Your Industry?

MMO Disc Anode is a high-efficiency mixed metal oxide (MMO) electrode designed for cathodic protection and electrochemical applications. It is manufactured using a titanium base coated with a catalytic MMO layer, providing excellent corrosion resistance, stable current distribution, and long operational lifespan. Its disc-shaped structure ensures uniform current output and high installation flexibility in confined or specialized environments.

MMO Disc Anode is widely used in impressed current cathodic protection systems, including tank bottom protection, marine structures, pipeline systems, and reinforced concrete corrosion control. Compared with conventional anodes, MMO Disc Anode offers lower consumption rates, higher energy efficiency, and significantly improved durability under aggressive environmental conditions.

Selecting the right MMO Disc Anode depends on factors such as soil or electrolyte resistivity, required current density, installation depth, and system design life. High-corrosion environments require higher coating loading and optimized disc surface area, while precision systems benefit from compact geometry and stable current output. Proper selection ensures maximum corrosion protection efficiency, reduced maintenance cost, and long-term structural safety.
