Cerium Foil

Cerium Foil is available in 31 variations that differ in thickness, width, length or temper. Cerium is a reactive rare earth metal with unique properties that include high heat capacity and low thermal expansion. Potential uses include incorporation into alloys, thin film coatings and investigations of cerium's catalytic and optical properties. With multiple options to choose from, Goodfellow's Cerium Foil enables flexible prototyping and customization for the research and development of this rare earth metal.
