Thulium Foil is an ultra-thin metal foil produced by Goodfellow. These foils showcase the malleability of thulium while maintaining the lustrous silvery-gray appearance of this rare earth metal. Offered in 12 variations, our thulium foils enable research and development across numerous high-tech applications, including semiconductor and laser technologies, where the metal's unique magnetic, electrical and optical properties are leveraged. Thulium's corrosion resistance also makes this foil well-suited for advanced material studies exploring everything from superconductivity to hydrogen storage.
