Nickel Expanded Mesh is manufactured by precision slitting and stretching of pure nickel sheets or nickel alloy coils. The process creates a uniform mesh with diamond-shaped openings, providing a large active surface area and excellent conductivity. This design enhances electrolyte flow and current distribution, making the expanded nickel mesh a suitable substrate for electrodes in alkaline water electrolysis and hydrogen production systems.

With high corrosion resistance in alkaline and electrochemical environments, nickel mesh ensures stable performance and long service life. Its lightweight yet robust structure reduces energy loss while maintaining high mechanical strength, supporting sustainable and efficient hydrogen generation.
