Elecrtodeposited Copper FoilsHow Metal Powders and Foils Are Produced

  • Electrolysis (Foil Formation)

    Copper foil is formed on a cathode surface by electroplating.

  • Surface Treatment

    Both sides of foil are treated to improve adhesion between foil and a substrate, heat resistance, oxidization resistance, etc.
    (Note: Details of treatment vary depending on the product type.)

  • Slitting, Cutting and Inspection

    Foil is formed into sheets and rolls.
