Nickel expanded mesh is a metal mesh material made from high-purity nickel plates through stamping or expanding processes, featuring uniformly distributed mesh holes and a strong sheet-like structure. Nickel expanded mesh combines the excellent properties of nickel—such as high electrical conductivity, outstanding corrosion resistance, and good mechanical strength—while providing good permeability and mechanical support due to its unique structural design. Nickel expanded mesh is widely used in filtration, battery current collectors, catalyst supports, architectural decoration, heat dissipation management, and more.
