As a leading manufacturer based in Hengshui, Hebei, Anping County Boli Hardware Wiremesh Products Factory (established 1998) specializes in high-precision woven wire meshes for critical industrial applications. Our Nickel 201 Woven Mesh — featuring a 0.12mm wire diameter and 120 mesh count — is specifically engineered for use in PEM electrolyzers (Proton Exchange Membrane electrolyzers), where consistent conductivity, corrosion resistance, and dimensional stability are paramount. With an annual export value exceeding US$5 million and shipments from major Chinese ports including Tianjin, Qingdao, Shanghai, and Foshan, we deliver reliable solutions to clients across North America, Europe, Asia, and beyond.
This product is manufactured from Nickel 201 (UNS N02201), a low-carbon version of Nickel 200, which offers excellent resistance to caustic environments and superior electrical conductivity. The 120 mesh configuration — with 120 openings per linear inch — provides an optimal balance between surface area and fluid permeability, making it ideal for use as a porous transport layer (PTL) or gas diffusion layer (GDL) in PEM electrolyzer cells. The 0.12mm wire diameter ensures fine filtration while maintaining mechanical strength under high-pressure and high-temperature operating conditions.

Advantages for PEM Electrolyzer Applications
- High Corrosion Resistance: Nickel 201 exhibits excellent resistance to the acidic and oxidative environment inside PEM electrolyzer cells, ensuring long service life without degradation.
- Excellent Electrical Conductivity: The low-carbon nickel alloy provides consistent electrical pathways, minimizing ohmic losses and improving overall cell efficiency.
- Uniform Mesh Structure: The 120 mesh precision weave guarantees uniform pore size distribution, which is critical for even gas distribution and water management in the electrolyzer stack.
- Mechanical Stability: Despite the fine 0.12mm wire, the mesh retains sufficient tensile strength to withstand the clamping forces and pressure differentials within a PEM cell.
- Customizable Dimensions: We can cut or slit the mesh to your exact cell dimensions, reducing waste and simplifying assembly.
- Surface Finish Options: Annealed (soft), cleaned (degreased), or as-woven finish — choose according to your process requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between Nickel 200 and Nickel 201 mesh?
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, making it the preferred choice for PEM electrolyzer applications where the mesh may be exposed to hot acidic conditions. -
Q: Can this mesh be used as a catalyst support in PEM electrolyzers?
A: Yes, the 120 mesh with 0.12mm wire provides a suitable substrate for coating with catalyst materials (e.g., iridium, platinum). The open area of ~36% allows good mass transport while maintaining electrical contact. -
Q: What is the tolerance on wire diameter and mesh count?
A: We adhere to industry standards: wire diameter tolerance is typically ±0.005 mm, and mesh count tolerance is ±2% per linear inch. Custom tolerances can be discussed for large-volume orders. -
Q: Is the mesh supplied in rolls or sheets?
A: Standard supply is in rolls of 30 m length x 1 m width. We can also cut sheets to your specified dimensions, or slit the roll into narrower widths. Please inquire for custom sizes. -
Q: How should I store the mesh before use?
A: Store in a dry, clean environment away from moisture and chemicals. The mesh is typically shipped with protective paper or plastic wrap. If kept in original packaging, it can be stored for extended periods without degradation. -
Q: Do you offer samples for testing?
A: Yes, we provide small sample pieces (e.g., 100x100 mm) for evaluation. The cost of the sample is nominal, and shipping is at the buyer's expense. Contact our sales team to arrange a sample. -
Q: What is the lead time for production?
A: For standard specifications (0.12mm/120 mesh/1m width), lead time is typically 7-10 working days after order confirmation. Custom sizes or weaves may require 15-20 days. We work efficiently to meet your project deadlines. -
Q: Can you provide certificates of conformity or material test reports?
A: Yes, we can issue a mill test certificate (MTC) for each batch, confirming the Nickel 201 composition and mechanical properties. This is especially important for OEMs and research institutions.
