Gold Foil

Designed for high-performance environments, Goodfellow's Gold Foil delivers exceptional purity and reliability - ideal for electronics, aerospace, biomedical implants, and scientific applications. Produced from 99.9% to 99.999% pure gold with ultra-tight thickness ranges (0.001 mm to 2 mm), it integrates seamlessly into assemblies where precision, quality, and repeatability matter. We offer in lengths and widths from 5 mm to 150 mm with optional polishing on both sides. Gold’s chemical inertness ensures corrosion resistance in aggressive environments, while its high melting point and boiling point support reliable performance under extreme heat. Its high density also delivers strength and stability even for ultrathin foils. Owing to its low electrical resistivity, it excels in high-frequency RF/microwave circuits, and its optical reflectivity supports use in infrared sensors and thermal control coatings. Combined with catalytic activity, biocompatibility and chemical stability, these properties make our gold foil the top choice for electrodes, connectors, thermal control coatings, and implantable medical devices.
