Fine Copper Wire Mesh Roll

Copper wire mesh is made of pure copper, copper has excellent electrical conductivity, thermal conductivity and ductility, it is one of the popular metal products because of its super electroconductivity malleability and flexibility making it the ideal material for electronics, electric power, communications industry and many other industries. Its reddish-orange color also makes it an ideal choice in the architectural industry.

The weaving method of copper mesh is generally plain weave or twill weave, and the mesh count can be up to 200 mesh/linear inch, which can be used in various industries. The standard length of woven copper mesh roll is generally 30m or 100 ft, customers can also cut according to the actual needs of the size.

The uses of copper wire mesh include RFI and EMI shielding, gasket, window screen, gas and liquid filtration, etc.
