High conductivity copper tape is used on both lightning protection and earthing applications. It is annealed for ease of use and has radiuses edges.
Copper tape has countless applications in electronics from creating low-profile traces for electrical components to RF-shielding and antenna-making. Copper tape is even used to join things together using solder, like the stained glass on Tiffany lamps. It comes in two forms; conductive adhesive and non-conductive adhesive
