Indium Wire Description
Indium wire is soft, flexible, and looks shiny like silver. It has a atomic weight of 114.82 and is in the 49th place on the periodic table. Pure indium wire is a great choice for sealing things because it covers imperfections in the surfaces where they meet. Indium wire is malleable even at cryogenic temperatures, so it performs well in harsh operating conditions. It is useful for sealing, cryogenic applications, and joining different non-metals. Indium wire is a good material for connecting heat, making it better at moving heat around.
Indium Wire Applications and Related Industries
Thermal interface: The thermal interface helps transfer heat between surfaces.
