Anping County Boli Hardware Wiremesh Products Factory, with over two decades of manufacturing excellence since 1998, proudly presents our premium Nickel Woven Mesh for Electrolyzer Electrode Support. This specialized mesh is engineered to withstand the harsh alkaline conditions typical in electrolysis processes, offering superior durability and consistent performance. As a trusted manufacturer with annual export value between US$5 million and US$10 million, we ensure every roll meets strict quality standards, making it the ideal choice for electrode support in alkaline water electrolyzers, chlor-alkali cells, and other electrochemical applications.
Our nickel woven mesh is produced from high-purity nickel wire, ensuring excellent corrosion resistance, electrical conductivity, and mechanical strength. The precise weave structure provides uniform openings and a stable support surface for catalytic coatings, maximizing gas evolution efficiency while minimizing pressure drop. Whether you need plain weave, twill weave, or dutch weave, we offer customizable options to match your specific process requirements.
Key Features & Technical Specifications
- Material Purity: Made from Ni200 (99.6% Ni) or Ni201 (99.9% Ni) – low carbon variant for improved weldability and corrosion resistance in alkaline media.
- Weave Options: Plain weave for general purpose, twill weave for finer filtration, and dutch weave for high strength and reduced pore size.
- Mesh Range: Available from 2 mesh (coarse) to 100 mesh (fine) to accommodate different electrode sizes and gas bubble management.
- Wire Diameter: 0.1 mm to 2.0 mm, with tight tolerances (±0.02 mm) to ensure consistent mechanical properties.
- Dimensional Flexibility: Standard width up to 2.0 meters, length per roll up to 50 meters, or cut-to-size sheets. Custom dimensions are welcome.
- Surface Condition: Supplied in annealed (soft) condition for easy forming, or as-woven for higher rigidity. Degreased surface is available upon request.
- Alkaline Durability: Tested for prolonged exposure to 30% KOH solution at 80°C – minimal weight loss and no structural degradation after 1000 hours.
Technical Data Table (Typical Values)
| Parameter | Value | Remarks |
|---|---|---|
| Material Grade | Ni200 / Ni201 | Custom grades available |
| Tensile Strength (as woven) | 400–550 MPa | Depends on wire diameter |
| Electrical Conductivity | ~22% IACS | Suitable for current distribution |
| Open Area | 30% – 75% | Depends on mesh count and wire diameter |
| Operating Temperature | Up to 300°C (in air) / 100°C in alkaline electrolyte | Limited by electrolyte boiling point |
| Corrosion Rate in 30% KOH @ 80°C | <0.05 mm/year | Excellent durability |
Advantages for Your Application
- Enhanced Electrode Lifespan: The nickel mesh resists embrittlement and cracking in alkaline environments, reducing maintenance frequency and replacement costs.
- Optimal Gas Release: Uniform mesh openings allow efficient escape of hydrogen and oxygen bubbles, preventing blinding and maintaining high current efficiency.
- Customizable for Coating: The woven surface provides excellent adhesion for catalyst layers (e.g., Raney nickel, NiFe, or NiMo), improving overall electrochemical performance.
- Low Contact Resistance: Nickel’s inherent conductivity ensures minimal voltage drop across the electrode support, saving energy in electrolysis.
- Versatile Formats: Available in rolls, sheets, or pre-cut pads to fit various electrolyzer designs, including monopolar and bipolar configurations.
We understand that every electrolyzer project has unique requirements. That’s why we offer customization services for mesh size, wire diameter, width, and surface treatment. Our in-house weaving facility allows rapid prototyping and short lead times, ensuring your production schedule stays on track.

Frequently Asked Questions
-
Q: What is the typical lifespan of this nickel mesh in an alkaline electrolyzer?
A: Under normal operating conditions (30% KOH, 80°C, with proper maintenance), the mesh can last several years. Actual lifespan depends on current density, temperature cycling, and chemical contamination. Our accelerated tests show less than 0.05 mm/year corrosion rate. -
Q: Can you supply the mesh in a roll form for continuous production?
A: Yes, we supply rolls up to 50 meters long and 2 meters wide. For larger electrolyzers, we can also provide cut-to-size sheets or custom shapes. -
Q: Is the mesh suitable for both anode and cathode support?
A: Absolutely. Pure nickel is stable in both anodic and cathodic conditions in alkaline electrolytes. However, for the anode side, we recommend Ni201 (low carbon) to avoid intergranular corrosion at high potentials. -
Q: Do you offer surface treatments like coating or activation?
A: We can supply the mesh in a degreased condition ready for coating. We do not apply catalyst coatings ourselves, but we can recommend compatible coating processes. Surface activation (e.g., etching) is available upon request. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on mesh specification. For standard sizes, MOQ is typically 10 square meters. For custom weaves, we may request a higher quantity. Please consult our sales team for details. -
Q: How do you ensure the mesh is free of contamination?
A: During production, we use clean nickel wire and avoid oil-based lubricants. After weaving, the mesh can be ultrasonically cleaned and degreased. We also offer optional vacuum packaging to prevent oxidation during storage. -
Q: Can you provide samples for testing?
A: Yes, we offer free samples (approx. 200x200 mm) for standard mesh sizes. Customers pay only shipping. Custom samples may incur a small cost. -
Q: What is the lead time for a standard order?
A: For standard mesh specifications, lead time is 15–20 working days after order confirmation. Custom orders may take 25–30 working days. Express delivery is available for urgent orders.
