Copper foil is a thin, flexible sheet or strip of copper, typically used in electrical applications as a conductor or shield. It is made by taking a thin sheet of copper and bonding it to a substrate material or backing, such as adhesive or non-adhesive paper or film.
C14420 copper is commonly used in electronics, especially in the manufacturing of printed circuit boards, as well as in decorative applications, like stained glass work. It is also used in the construction industry for roofing and flashing.
