Product Features

As an important lightning protection method, lightning protection metal mesh has achieved very important applications in aircraft. The common metal mesh for lighting protection includes woven mesh, copper expanded metal foil and perforated sheet. The disadvantage of the woven mesh is that the surface of the composite curvature is difficult to cover, which affects the aerodynamic performance, and the lap resistance between the metal wires of the woven mesh is relatively large, and the lightning protection effect is far less than that of the copper expanded metal. The woven wire mesh is also prone to breakage and disintegration due to the strong electromagnetic force generated by the lightning current.

Scope of application

Important application of copper expanded metal:

Aerospace

Wind Energy

Battery mesh

Electrolyzer

Filtration

EMI shielding

Automotive

flue gas denitrification
