If you purchase mixed metal oxide (MMO) titanium anodes — whether for chlor-alkali, wastewater treatment, cathodic protection, or electrolytic copper foil — you've likely noticed upward pressure on pricing.

The performance of a titanium anode is defined by its catalytic coating. Key parameters such as coating uniformity, thickness, composition, crystal structure, and microscopic morphology directly determine electrochemical activity, service life, and current efficiency.

NW HENGYI METAL recently completed a project for a cathodic protection application in a soil environment, where the customer specified an iridium-tantalum coating at 5μm—a specification that sits at the higher end of the typical range for MMO anodes in this industry.

China's titanium anode industry has evolved from a period of import dependence and technological catch-up to one of independent innovation and global leadership. Its growth is closely tied to the nation's industrialization, particularly in key sectors such as chlor-alkali chemicals, environmental protection, and marine engineering.

​As the Christmas and New Year holidays approach, NW HENGYI METAL hosted a special year-end celebration to express gratitude to our hardworking employees. The event featured a warm and festive hotpot dinner, bringing everyone together to share delicious food and joyful conversations.

The integrity of a cathodic protection (CP) system depends on every single component. Beyond our industry-leading MMO (Mixed Metal Oxide) Titanium Anodes, the unsung hero ensuring sustained performance is the critical connection – the cable. Today, we are proud to detail the engineering excellence behind our standard and robust cable system, the backbone that delivers protection to your assets.

At N.W. HENGYI METAL, we specialize in advanced corrosion protection solutions, delivering top-tier quality and reliability.

Ever wondered how critical infrastructure like pipelines, water tanks, and marine structures are protected from the relentless attack of corrosion? The unsung hero is often the Discrete Anode.

Titanium anodes (typically coated with precious metal oxides like RuO₂-IrO₂) used in chlorine electrolysis cells generally have a lifespan of 3–8 years under normal operating conditions. High-performance coatings (e.g., RuO₂-IrO₂-Ta₂O₅) can last over 10 years with optimized process parameters.

For tank bottom cathodic protection systems, MMO ribbon anodes, titanium conductor bars, and anode power feed connectors are critical components ensuring long-term anti-corrosion performance.
