Description
Grade 1 Titanium Anode – MMO Coated
🔎 Introduction
Select a coated electrode using both substrate and coating requirements. The GR1 Titanium Anode uses commercially pure titanium with a selected MMO formulation for the defined electrolyte, target reaction and current duty. Send the drawing, dimensions, active area, connection and inspection requirements for a quotation.
Unlike palladium-bearing Grade 7, GR1 titanium is a commercially pure grade valued for ductility and formability. Its coating is selected independently to create an MMO-coated titanium anode for specified electrolysis, water-treatment or impressed-current protection conditions.
🧪 What Makes GR1 Titanium Unique?
GR1 titanium is a ductile commercially pure grade. The catalogue 99.5% titanium reference requires confirmation of the ordered specification and lot-analysis basis; substrate identity does not establish catalytic activity or finished-electrode life.
Key characteristics of GR1 Titanium Anode substrate:
-
✅ Commercially pure substrate selected by the ordered grade specification, impurity limits and lot documents
-
✅ Corrosion selection based on the actual solution, concentration, pH and temperature
-
✅ Outstanding formability, making it suitable for mesh, plate, rod, and tubular anode designs
-
✅ Lightweight and easy to fabricate, enabling cost-efficient manufacturing
👉 Select GR1 when ductility, forming requirements and the ordered substrate specification suit the drawing; choose the coating separately for the intended reaction and operating conditions.
⚡ Role of MMO Coating
The titanium substrate carries current; the Mixed Metal Oxide (MMO) coating provides the catalytic surface selected for the target anodic reaction. Confirm coating formulation/loading and process conditions rather than inferring activity from titanium purity.
MMO Coating Components
-
IrO₂ (Iridium Oxide): A catalytic component considered within the complete formulation for the selected reaction and electrolyte
-
RuO₂ (Ruthenium Oxide): A catalytic component often considered for chlorine-evolving service; confirm formulation suitability for the actual medium
-
Ta₂O₅ (Tantalum Oxide): A component used in some mixed-oxide formulations; agree the composition and inspection requirements
Advantages of MMO Coating on GR1 Substrate
-
⚡ Catalytic formulation selected for the specified reaction and current duty
-
🛡 Coating adhesion verified by the ordered test method and acceptance criteria
-
⏳ Catalogue life reference of 5–10 years to be assessed against coating loading, environment, current duty and the agreed life basis
-
♻️ Coating and process selection considered with the required product-water or effluent criteria
⚖️ Comparison: GR1, GR2 & GR7 Substrate References
| Feature | GR1 Titanium Anode (MMO) | GR2 Titanium Anode (MMO) | GR7 Titanium Anode (MMO) |

| Mechanical Strength | Lower (most ductile) | Moderate | Moderate |
| Corrosion Resistance | Excellent in most media | Excellent, broader applications | Superior in extreme chloride |
| Fabrication Ease | Very high | High | Moderate |
| Cost Efficiency | Most economical | Balanced | Higher due to Pd content |
| Best Applications | General electrolysis, water treatment | Industrial electrolysis, plating | Offshore, seawater electrolysis |
👉 Selection note: Compare substrate forming and corrosion requirements together with the coating and current duty required for the specific project. The comparison table is a catalogue selection reference; verify the ordered material and performance criteria in the quotation.
🌟 Advantages of GR1 MMO Coated Titanium Anode
💎 1. Substrate and Environment Selection
For the GR1 Titanium Anode, confirm the commercially pure substrate specification, lot documents, surface preparation and suitability for the actual solution. Titanium content alone does not determine coating performance.
⚡ 2. Reaction and Energy Assessment
For an MMO-coated titanium anode, assess current efficiency and energy use under the defined coating, active area, cell geometry and operating conditions.
⏳ 3. Service-Life Basis
The catalogue 5–10 years reference requires a coating-loading, current-duty, electrolyte and life-assessment basis agreed for the order.
♻️ 4. Process Acceptance Requirements
Select the coating together with the required process chemistry, gas handling, product-water quality or effluent criteria; inspect the electrode against the agreed requirements.
🔧 5. Easy Customization
Use the GR1 substrate form and manufacturing route appropriate to the drawing for plates, meshes, rods, tubes, or wires. Confirm the corresponding ordered substrate-form standard and coating requirements.
