Description
Powerful Titanium Anode Rod – 99.9% MMO Coated GR1/GR2
🔹 Introduction
The Titanium Anode Rod is an advanced electrochemical component designed for superior performance in harsh industrial environments. Manufactured using high-purity GR1 or GR2 titanium and coated with 99.9% Mixed Metal Oxides (MMO) such as IrO₂/RuO₂, this anode is engineered to withstand corrosive media while maintaining stable electrochemical efficiency. It plays a critical role in applications such as electrolysis, water treatment, electroplating, chlorine production, and cathodic protection systems.
This product is an ideal upgrade from conventional graphite or lead-based electrodes due to its exceptional lifespan, low maintenance needs, and energy-efficient performance. Whether referred to as a Titanium Anode Rod, MMO Coated Titanium Rod, or Electrolysis Anode Rod, it is a reliable and customizable solution for modern electrochemical systems.

🌮 Material & Coating
Our Titanium Anode Rods are crafted from commercially pure Grade 1 or Grade 2 titanium, selected for its strength, weldability, and chemical stability. The MMO coating, composed mainly of ruthenium oxide (RuO₂) and iridium oxide (IrO₂), is applied via thermal decomposition or brush-coating and sintering. This coating provides:
- ✅ Low overpotential for chlorine or oxygen evolution
- ✅ Uniform current distribution
- ✅ High catalytic activity
- ✅ Excellent adhesion to titanium
This Ru-Ir Coated Titanium Rod can also be customized with alternative MMO systems such as Ta₂O₅, SnO₂, or Pt coatings for specific industrial needs.
🚀 Performance Advantages
✨ Superior Durability
The MMO layer ensures superior corrosion resistance in acidic and alkaline solutions, allowing operation in:
- Chloride-rich brine
- Acidified sulfate solutions
- Hypochlorite cells
✨ Energy Efficiency
- Low energy consumption thanks to optimized electrochemical kinetics
- Reduced cell voltage and minimal polarization loss
✨ Long Service Life
- 5000 to 10000 hours depending on usage conditions
- Recoatable titanium base enables reusability
✨ Lightweight & Strong
- Easier to handle and install than lead or graphite alternatives
- Excellent mechanical strength and resistance to warping

❓ Frequently Asked Questions (FAQ)
Q1: What’s the difference between GR1 and GR2 titanium rods?
A: GR1 is softer and more ductile, easier to form and weld. GR2 offers higher strength. Both are suitable for MMO coating.
Q2: Can the rods be reused after coating degrades?
A: Yes, we offer re-coating services for titanium rods. The base remains structurally intact.
Q3: What coating types are available besides Ru-Ir?
A: Ta₂O₅, SnO₂, Pt, and multi-oxide blends for different media.
Q4: Can I use these rods in seawater electrolysis?
A: Yes, the coating is ideal for chloride-rich environments.
Q5: Can you manufacture threaded or flanged rods?
A: Absolutely, we support full machining as per drawings.
