Indium Foil/Sheet/Plate is made from pure Indium Ingot which is a very soft and shapable metal. It has great thermal conductivity used as an inefficient heat sink for high-temperature and cryogenic applications. Santech produces Indium foil in the various sizes listed as follows, the production process is very advanced to ensure extremely precise dimensions and high purity without glycerin and contamination. Indium foil is packed inside two hard plastic sheets to make sure the flatness and suitable for transportation.
