Product Overview
Our Pure Iron Anodes are engineered specifically for electrolytic processes in the chemical industry. Produced in our own foundry with stringent metallurgical control, these anodes offer high electrochemical efficiency, uniform dissolution, and extended service life in aggressive electrolyte environments. They are the ideal choice for applications requiring reliable and consistent performance in electrochemical synthesis, metal recovery, and effluent treatment.
Key Features (Chemical Electrolysis-Specific Advantages)
✅ Ultra-Low Impurity Profile
Carbon (≤0.004%), phosphorus (≤0.008%), and sulfur (≤0.006%) levels prevent impurity leaching into electrolytes-critical for producing high-purity chemicals (e.g., pharmaceutical-grade caustic soda) and avoiding catalyst poisoning.
✅ Enhanced Corrosion Resistance
Proprietary surface treatments (passivation, acid-resistant plating, or ceramic coating) reduce corrosion rates by up to 80% in aggressive electrolytes (e.g., 30% NaOH, 20% HCl) compared to unprocessed pure iron.
✅ Stable Electrical Conductivity
Pure iron's inherent conductivity (100 S/m at 20°C) remains consistent over long-term use-ensures uniform current distribution across the electrolytic cell, avoiding hotspots that damage cell membranes or electrodes.
✅ Mechanical Stability in Process Conditions
Retains tensile strength (≥310 MPa) and dimensional integrity at electrolysis temperatures (50–90°C) and pressures (1–5 bar)-prevents component warping that disrupts cell alignment or fluid flow.
✅ Compatibility with Common Electrolytes
Tested and validated for use with chlor-alkali (NaCl/NaOH), metal electrowinning (CuSO₄, ZnSO₄), and organic synthesis (sulfuric acid-based) electrolytes-no risk of chemical incompatibility.
✅ Customizable for Cell Designs
Available in custom shapes (plates, tubes, frames, brackets) and sizes (from 50mm small parts to 2000mm cell frames) to match your electrolytic cell blueprint-supports both monopolar and bipolar cell configurations.
