Composition Analysis
Every batch is validated via ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy) to meet stringent bath stability requirements:
| Element | Content (ppm) | Role in Electrolytic Performance |
|---|---|---|
| Fe | ≥99.97% | Primary conductor with minimal ionic interference |
| C | ≤20 | Prevents carbon sludging in acidic baths |
| S | ≤5 | Eliminates sulfide-induced passivation |
| O | ≤50 | Reduces oxide layer formation |
| Cu | ≤3 | Avoids galvanic displacement in copper electrolytes |
| Cl | ≤2 | Critical for chloride-sensitive processes (e.g., gold refining) |
| Trace Metals | ≤15 (Ni, Cr, Zn) | Strictly controlled to prevent alloy contamination |
Key Advantages
Acid/Alkali Resilience
Proprietary passivation layers reduce pitting corrosion by 70% in pH 1–13 environments, ideal for zinc electrowinning and chrome plating.
High Current Efficiency
Uniform resistivity (12–18 μΩ·cm) ensures stable current distribution, improving metal deposition uniformity by up to 40%.
Custom Geometry
Laser-cut perforations, embossed patterns, or pre-bent shapes to optimize electrolyte flow and gas venting in complex bath designs.
Recyclability
100% recyclable material with closed-loop production, supporting circular economy goals in mining and electroplating industries.
Rapid Replacement
Pre-qualified material grades for retrofitting existing bath systems without process requalification.
Industry Applications
Metal Refining: Copper cathode starter sheets, cobalt/nickel electrowinning anodes.
Surface Finishing: Hard chrome plating racks, decorative gold/silver electroforming mandrels.
Environmental Tech: Electrocoagulation modules for heavy metal removal, hydrogen peroxide synthesis cells.
Chemical Processing: Chlor-alkali membrane cell cathodes, sulfuric acid regeneration plates.
R&D: Custom-thickness foils for experimental flow batteries or ion-exchange membranes.

Technical FAQs
Q: How does your iron compare to titanium for sulfuric acid electrolysis?
A: Our PTFE-coated iron coils offer 85% cost savings vs. titanium with comparable corrosion rates (<0.1mm/year in 30% H₂SO₄). Uncoated variants suit short-duration plating baths.
Q: Can you supply pre-oxidized coils for passive film formation?
A: Yes! Controlled thermal oxidation creates a 2–5μm Fe₃O₄ layer, ideal for reducing initial bath conditioning time.
Q: Do your coils support ultrasonic welding for modular bath assemblies?
A: Absolutely. Our low-carbon variants (C ≤50ppm) enable seamless welding without brittle intermetallic formation.
