Product Features

Expanded Copper Foil is stretched by pressing machine to expand the metal plate to the required size. Therefore, compared with woven mesh and perforated sheet, copper expanded metal has no material waste and low cost. The more important is that the strand of Expanded Copper Foil is more uniform, and there will be no sudden change in the current conduction cross-section, which will affect the electrical conductivity.


Scope of application

  • Electrochemical conductor in new batteries

  • EMI Shielding expanded copper foil

  • Wind powder

  • Lightning protection of wind turbine blades

  • Wind power blade copper expanded metal

  • battery mesh

  • Current collector network
