Indium Foil

Indium Foil is a pure metal foil offered in 153 variations, so you can select the ideal foil thickness, temper and size to meet your needs. This foil is known for its softness, malleability and low melting point. It’s used in specialized solders, thin film coatings and as a sealing material. Researchers also employ Indium Foil in cryogenic applications to take advantage of its superconducting properties at low temperatures.
