According to QYResearch survey data, the global MMO/Ti flexible anode market size is projected to reach approximately $237 million in 2024, growing to $329 million by 2031 with a compound annual growth rate (CAGR) of 4.8% during the 2025-2031 period. As a precious metal oxide-assisted anode material, MMO tubular anodes demonstrate significant technical advantages in cathodic protection. Featuring a titanium substrate coated with electrocatalytically active metal oxides, these anodes maintain extremely low polarization currents in diverse environments including soil, freshwater, and seawater. The steady global market growth reflects the expanding application scope of MMO anodes across various industrial sectors.
Major manufacturers of MMO tubular anodes in the international market include Umicore, Industrie De Nora (DSA anode), Farwest Corrosion Control Company, Syncor Cathodic Protection, Uyemura, BSS Technologies, and Matcor. These manufacturers offer MMO tubular anodes in various specifications, such as the Φ25×1000mm model with a current density of 8.0A, the Φ25×700mm model at 5.0A, and the Φ50×1000mm model capable of 15.0A. Different brands of MMO tubular anodes feature distinct coating compositions and current density designs to meet specific customer requirements across diverse application environments.
The recycling value of MMO tubular anodes primarily stems from their precious metal content. Titanium anodes (MMO) are formed by coating precious metal iridium salts onto a titanium substrate and sintering at high temperatures. These precious metal components confer substantial recycling and reuse value. Discarded MMO tubular anodes are typically processed through remelting to extract valuable metallic materials. As the MMO tubular anode market continues to expand, a comprehensive recycling system is emerging. Professional recycling processes not only minimize resource waste but also provide users with residual value returns, further enhancing the anodes' lifecycle economics.

MMO tubular anodes play a vital role across multiple industrial sectors. In the petrochemical industry, they are extensively used for cathodic protection of tank bottoms. Installed in mesh or concentric ring patterns, they provide corrosion protection for large storage tanks for over 20 years. In marine engineering, MMO tubular anodes are the preferred anode material in seawater environments due to their corrosion resistance and high current density. They are particularly suitable for facilities like ships, docks, and subsea pipelines. Municipal construction also extensively utilizes MMO tubular anodes, especially for protecting reinforced concrete structures. These anodes effectively inhibit rebar corrosion, significantly extending structural lifespan. Furthermore, within the energy sector, MMO tubular anodes safeguard oil pipelines traversing challenging terrains like deserts and permafrost. By deploying deep-well anode arrays, the protective radius extends up to 150 meters. These diverse applications fully demonstrate the adaptability and reliability of MMO tubular titanium anodes as high-performance corrosion protection materials.
