Welcome to Anping County Boli Hardware Wiremesh Products Factory – your trusted partner in industrial wire mesh solutions since 1998. We are proud to present our Nickel 201 Screen for Hydrogen Evolution, 50 Mesh, 0.2mm Wire, 1m x 10m, Industrial Grade. This high-performance mesh is specifically engineered for electrochemical hydrogen production, offering superior corrosion resistance and electrical conductivity in harsh alkaline environments. As a manufacturer with over two decades of experience and annual export values between US$5–10 million, we ensure every roll meets the highest standards of quality and consistency.
Whether you are a research lab or an industrial electrolyzer manufacturer, our Nickel 201 screen provides the reliable performance you need for efficient hydrogen evolution reactions (HER). The 50-mesh configuration with 0.2mm wire diameter balances mechanical strength with high open area, maximizing active surface area while maintaining structural integrity. Below, we break down the key specifications and advantages of this product.
Technical Specifications
| Material | Nickel 201 (UNS N02201) – Low carbon content (≤0.02% C) for enhanced corrosion resistance |
| Mesh Count | 50 Mesh (50 openings per linear inch) |
| Wire Diameter | 0.2 mm (0.008 inch) |
| Aperture Size | Approximately 0.308 mm (0.0121 inch) |
| Open Area | ~36% (allows efficient electrolyte flow and gas release) |
| Dimensions | 1 meter width × 10 meters length per roll |
| Grade | Industrial Grade – suitable for continuous operation in electrolysis cells |
| Weave Type | Plain Weave – uniform, tight structure |
Key Features & Benefits
- High-Purity Nickel 201: Low carbon content (≤0.02%) minimizes carbide precipitation at grain boundaries, providing excellent resistance to intergranular corrosion in alkaline media. This is critical for long-term stability in hydrogen evolution applications.
- Optimized Mesh Geometry: The 50 mesh with 0.2mm wire diameter offers a balanced ratio of open area to mechanical strength. The larger open area (~36%) reduces gas bubble accumulation and enhances mass transfer, improving overall cell efficiency.
- Industrial-Grade Durability: Manufactured with precision weaving and controlled tension, this screen withstands the mechanical stresses of repeated thermal cycling and high current densities typical in industrial electrolyzers.
- Uniform Pore Distribution: Consistent aperture size ensures predictable current distribution across the electrode surface, leading to more uniform hydrogen bubble detachment and reduced overpotential.
- Easy to Handle & Fabricate: The 1m × 10m roll format is convenient for cutting to custom sizes for electrodes, separators, or gas diffusion layers. The material is malleable and can be welded or shaped as needed.
- Corrosion Resistance in Harsh Environments: Nickel 201 is specifically designed for use in caustic solutions (e.g., 30% KOH at 80–90°C), making it an ideal choice for alkaline water electrolysis systems.
- Cost-Effective Alternative to Higher-Grade Alloys: While offering performance close to Nickel 200, the 201 grade is more economical for large-scale industrial applications where low carbon content is sufficient.
Applications in Hydrogen Evolution
This Nickel 201 screen is widely used as:
- Cathode/Anode substrate in alkaline electrolyzers for hydrogen and oxygen production.
- Gas diffusion layer in proton exchange membrane (PEM) electrolyzers (where nickel compatibility is acceptable).
- Support structure for catalytic coatings (e.g., Raney nickel, NiFe, or NiMo).
- Electrode mesh in chlor-alkali cells and other electrochemical processes requiring high-surface-area nickel.
- Filter or separator in hydrogen purification systems.

Frequently Asked Questions
-
Q: What is the difference between Nickel 200 and Nickel 201?
A: Nickel 201 has a lower carbon content (≤0.02%) compared to Nickel 200 (≤0.15%). This makes Nickel 201 more resistant to intergranular corrosion at elevated temperatures, especially in caustic environments typical for hydrogen evolution. -
Q: Can this screen be customized to different sizes?
A: Yes, we offer customization. You can order different widths, lengths, mesh counts, wire diameters, or even cut-to-size pieces. Please contact us with your requirements. -
Q: Is this product suitable for alkaline water electrolysis?
A: Absolutely. Nickel 201 is a standard material for alkaline electrolyzer electrodes (e.g., in 30% KOH at 80°C). The 50-mesh design provides good surface area and bubble release. -
Q: How do you ensure the quality of the mesh?
A: We perform 100% inspection on roll dimensions, wire diameter, mesh count, and visual defects. Material certificates from our mill are available upon request for each batch. -
Q: What is the typical packaging for shipping?
A: The mesh is wound on sturdy cardboard cores, wrapped in plastic film, and then packed in craft paper or wooden crates for export. We can also supply with anti-corrosion treatment if needed. -
Q: What is the lead time for bulk orders?
A: For standard 1m×10m rolls, lead time is typically 10–15 working days after order confirmation. Customized orders may require 20–25 days. Rush orders are available upon request. -
Q: Can you provide samples before bulk purchase?
A: Yes, we can send small samples (e.g., 100mm×100mm) for evaluation. Sample cost is negotiable, and shipping is usually at the buyer's expense. Contact us for details. -
Q: Is this screen conductive enough for electrochemical applications?
A: Nickel has excellent electrical conductivity (approx. 22% IACS). The 0.2mm wire diameter provides low resistance, and the large open area ensures good electrolyte contact. For high-current applications, we recommend using multiple layers or a thicker wire if needed.
