Copper mesh is a metallic mesh material woven from copper wires, possessing properties such as electrical conductivity, thermal conductivity, non-magnetic properties, wear resistance, and corrosion resistance.
Copper mesh is divided into three categories based on its material:
Brass mesh: Contains 65% copper and 35% zinc, with a mesh count of 10-100 meshes per inch, and a width of 0.5-1.5 meters. It is used for particle screening and liquid filtration.

Copper mesh: Purity ≥99.8%, mesh size 4-60 mesh/inch, width 0.76-1.2 meters, suitable for electromagnetic shielding and electron beam filtering.
Phosphor bronze mesh: Contains 5%-15% tin, with a mesh count of up to 400 meshes per inch, and a width of 1 meter. It is used for corrosion-resistant gas filtration and ceramic printing.
