As a professional manufacturer with over 26 years of experience, Anping County Boli Hardware Wiremesh Products Factory is proud to offer high-quality Nickel 200 Expanded Mesh specifically designed for hydrogen production applications. Our nickel expanded mesh is precision-engineered with a 1.2mm wire diameter and a 5mm x 10mm diamond pattern, supplied in convenient 500mm x 1000mm coils. This product is essential for electrolysis electrodes, gas diffusion layers, and catalyst supports in the hydrogen industry, providing excellent corrosion resistance and electrical conductivity.
The Nickel 200 alloy contains 99.6% pure nickel, offering outstanding resistance to caustic alkalis and reducing environments. Our expanded mesh is manufactured through a slitting and stretching process that creates a strong, monolithic structure without any welded joints, ensuring uniform mechanical properties across the entire coil. The diamond pattern (5mm x 10mm) provides optimal open area for fluid/gas flow while maintaining structural integrity.

Product Features & Benefits
- High Purity – Nickel 200 with 99.6% Ni content ensures minimal contamination in hydrogen production processes.
- Excellent Corrosion Resistance – Resistant to caustic soda, dilute acids, and alkaline electrolytes used in water electrolysis.
- Consistent Diamond Pattern – Uniform 5mm x 10mm openings provide reliable fluid distribution and gas release.
- Strong & Durable – Expanded construction eliminates weak points; no welding or weaving to fail.
- Convenient Coil Form – 500mm x 1000mm coil is easy to handle, cut, and install for custom electrode sizes.
- Customizable – Available in different wire diameters, mesh sizes, and coil dimensions upon request.
Our Nickel 200 expanded mesh is widely used in alkaline water electrolyzers, proton exchange membrane (PEM) electrolyzers, and hydrogen generation systems. The diamond pattern optimizes the balance between mechanical strength and open area, allowing efficient gas bubble release and electrolyte flow. With a thickness equal to the wire diameter, the mesh offers good electrical conductivity for electrode applications.
We understand that hydrogen production environments are demanding. That's why we carefully control the mesh dimensions and material purity to meet the stringent requirements of the renewable energy industry. Each coil is inspected for pattern uniformity, wire diameter consistency, and surface condition before packaging.

Frequently Asked Questions
Q1: What is the exact composition of Nickel 200?
A: Nickel 200 contains a minimum of 99.6% nickel, with small amounts of iron, manganese, carbon, silicon, and copper. It is a commercially pure wrought nickel grade.
Q2: Can this mesh be used in high-temperature hydrogen production?
A: Nickel 200 is suitable for temperatures up to 315°C (600°F) in oxidizing environments and up to 600°C (1112°F) in reducing conditions. For alkaline electrolysis (typically 60-90°C), it works perfectly.
Q3: What is the open area percentage of the 5mm x 10mm pattern?
A: The approximate open area is 60-65%, depending on the amount of stretching during production. This provides a good balance between flow capacity and mechanical strength.
Q4: Do you offer custom coil sizes or cut pieces?
A: Yes, we can customize the coil width, length, and even supply sheets or strips. Please provide your required dimensions, and we will quote accordingly.
Q5: How is the mesh packaged for export?
A: Each coil is wound on a plastic spool or steel reel, wrapped with protective material, and packed in a plywood case or wooden pallet to prevent damage during shipping.
Q6: What is the lead time for bulk orders?
A: For standard specifications, lead time is typically 15-20 working days. For custom sizes, it may be 25-30 working days depending on volume.
Q7: Can I get a sample before placing a large order?
A: Yes, sample orders are welcome. We can provide a small piece (e.g., 200mm x 200mm) for evaluation. Sample cost is negotiable, and shipping is at your expense.
Q8: Is this mesh suitable for PEM electrolyzers?
A: In PEM electrolyzers, nickel mesh is often used as a current collector or gas diffusion layer. However, for the acidic environment of PEM, a coating (e.g., platinum) may be required. Our nickel mesh can serve as a base material for further coating.
