Indium shot is widely used in the electronics and semiconductor industries due to its excellent thermal and electrical conductivity. It serves as a key material in the production of transparent conductive coatings, especially in flat-panel displays, touchscreens, and OLEDs, where it is used in the form of indium tin oxide (ITO).

It is also employed in low-melting-point alloys for specialized soldering and sealing applications, particularly in cryogenics and vacuum systems, where reliable, hermetic seals are required. Its softness and malleability allow it to form effective seals between metals and glass without damaging sensitive components.

In thermal interface materials, indium shot is used to create efficient heat transfer paths in high-performance electronic devices such as lasers, LEDs, and power amplifiers, where managing heat is critical.

Additionally, it plays a role in the manufacture of solar cells and in certain types of nuclear reactors as a neutron absorber. Its ability to bond dissimilar materials and maintain integrity at low temperatures makes it valuable in aerospace and defense technologies.
