Copper has excellent electrical conductivity, making it effective in shielding electromagnetic signals. And the higher the purity of the copper material, the better the electromagnetic shielding, especially for high frequency electromagnetic signals. The high purity copper foil produced by CIVEN METAL is an ideal electromagnetic shielding material with high purity, good surface consistency, and easy lamination. The material can be annealed to provide a better shielding effect and is easy to cut into shapes. At the same time, in order to adapt the material to the harsher use environment, CIVEN METAL can also apply electroplating process to the material, so that the material has better resistance to high temperature and corrosion.Copper Foil High-precision RA Copper Foil Tin Plated Copper Foil Nickel Plated Copper Foil Adhesive Copper Foil Tape *Note: All the above products can be found in other categories of our website, and customers can choose according to the actual application requirements.
