Kupferfoil

Kupferfoil is a term often used in German-speaking countries to refer to thin copper sheeting or foil. Its primary applications leverage copper's excellent conductivity, malleability, and corrosion resistance. In electrical engineering, Kupferfoil is a fundamental component in printed circuit boards (PCBs), forming the conductive pathways that connect electronic components. It is also utilized in flexible electronics and electromagnetic shielding.

Beyond electronics, Kupferfoil finds use in decorative arts and construction. Its pliable nature allows it to be shaped and embossed for architectural elements, roofing, and historical restoration projects. In some industrial processes, it serves as a material for heat exchangers due to copper's high thermal conductivity. The manufacturing process typically involves rolling copper ingots to achieve the desired thinness, with specialized techniques employed for producing very fine foils. The quality and thickness of Kupferfoil are critical factors determining its suitability for specific applications, with tolerances often measured in micrometers. Its recyclability also contributes to its sustainable use in various industries.
