Tungsten Foil

Engineered for extreme environments, Goodfellow's Tungsten Foil offers unmatched thermal resilience, mechanical strength, and dimensional stability - making it indispensable in aerospace, semiconductor, medical, and scientific applications. Manufactured from 99.95% pure tungsten with ultra-precise thickness ranges (0.003 mm to 50 mm), it integrates seamlessly into assemblies demanding high temperature endurance, density, and reliability. Available in lengths up to 600 mm and widths up to 300 mm, with optional polishing on one side, our foil delivers consistent surface quality. Tungsten’s high melting point and low vapor pressure ensure structural stability at extreme temperatures, while its high density provides strength and radiation shielding. Its minimal thermal expansion and stable conductivity make it ideal for vacuum electronics, heat spreaders, and ion implantation systems. Resistant to corrosion and chemically inert, tungsten foil excels in high-vacuum, high-temperature, and high-radiation conditions. Its formability and wear resistance support precision fabrication for sputtering targets, shielding, and diagnostic components. These properties make our tungsten foil the material of choice for demanding applications in aerospace insulation, semiconductor processing, medical imaging, and advanced research systems.
