Bismuth Foil

Bismuth Foil is available in 73 variations, with thicknesses from 0.025mm to 2mm. This metallic foil exhibits a pinkish, silvery metallic lustre and is brittle with low thermal and electrical conductivity. Applications of Bismuth Foil include radiation shielding, thermoelectric devices and research. Its unique diamagnetic properties also make it useful for levitation experiments and demonstrations. The availability of high purity Bismuth Foil in different thicknesses from Goodfellow allows scientists and engineers to select the ideal material for their specific application.
