Silver Foil

Designed for high-performance environments, Goodfellow's Silver Foil delivers unmatched conductivity, reflectivity, and formability - ideal for electronics, energy systems, medical devices, and scientific instrumentation. Produced from 99.9% to 99.999% pure silver with tight thickness ranges (0.001 mm to 6 mm), it integrates seamlessly into assemblies requiring precise thermal management, low electrical resistance, and high optical performance. We offer in lengths and widths up to 300 mm with optional polishing on one side to ensure surface uniformity and precision. Silver’s electrical and thermal conductivity minimizes energy loss and supports high-frequency signal transmission, while its exceptional reflectivity makes it indispensable in optical coatings and solar applications. Its chemical stability ensures long-term reliability in harsh environments, and its ductility allows cold forming into ultra-thin interconnects and flexible components. With catalytic activity and antimicrobial properties, silver foil is the material of choice for EMI shielding, thermal interface materials and photovoltaic systems.
