Nickel foil stretched mesh is a high-performance material created by mechanically expanding or etching thin nickel foil to form a mesh with uniform openings. This specialized mesh is widely used in applications requiring high conductivity, corrosion resistance, and structural stability, such as fuel cells, battery electrodes, EMI shielding, and catalytic layers. In 2025, the number of manufacturers offering nickel foil stretched mesh is steadily increasing, with several regions emerging as major production centers. This article explores leading global suppliers, their capabilities, and how to choose the right mesh for your application.
What is Nickel Foil Stretched Mesh?
Nickel foil stretched mesh is typically produced from pure nickel foil (≥99.5%) with thicknesses ranging from 0.01 mm to 0.1 mm. The mesh can be created through stretching (expanded metal) or precision etching to form uniform hexagonal or diamond-shaped holes. It is characterized by:
• Excellent thermal and electrical conductivity
• High corrosion resistance in alkaline and acidic environments
• Light weight and high surface-area-to-volume ratio
• Good flexibility and formability

How to Evaluate a Mesh Manufacturer
1. Tolerance Control: Top manufacturers maintain opening width tolerance within ±0.01 mm, critical for battery and fuel cell uniformity.
2. Quality Assurance: Look for ISO9001-certified factories that provide MTCs (Material Test Certificates) and dimensional reports.
3. Customization Capability: Ensure the supplier can customize mesh shape, thickness, and roll size for your specific requirements.
4. Export Experience: Companies with export history typically offer better packaging, documentation, and customer service.
Lead Time and MOQ by Supplier Type
| Supplier Type | Lead Time | MOQ |
|---|---|---|
| Large Manufacturer | 2–4 weeks | 10–50 m² |
| Custom Etching Factory | 3–7 days | 1 sheet or 1 roll |
| Online Distributors | 1–3 days | No MOQ |
Markets with Growing Demand in 2025

Related Questions and Answers
What is the minimum thickness of nickel foil mesh available?
Leading manufacturers like Tech-Etch and Dexing can produce nickel foil stretched mesh as thin as 0.01 mm, ideal for energy storage and precision electronics.
What is the difference between etched mesh and expanded mesh?
Etched mesh is chemically or laser-cut from foil with precise patterns, offering high dimensional accuracy, while expanded mesh is mechanically stretched, more economical, but with less precision.
Where can I source nickel foil mesh with custom hole size?
Custom hole sizes can be ordered from manufacturers like Veco (Netherlands), Precision Eforming (USA), or Xinxiang Dexing (China), all of whom offer tailored mesh solutions based on technical drawings.
