Bismuth Foil

99% - 99.999% pure

Bismuth is a white, crystalline, brittle metal with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal, except mercury. It has a high electrical resistance, and has the highest Hall Effect of any metal (i.e., greatest increase in electrical resistance when placed in a magnetic field).

Our Bismuth foil is a thin sheet of pure metal. With its’ fragile nature, some foils will require a protective coatings. Ultra-thin foils may be mounted on a polyester back support.
