Indium wire In-0 - Indium N3
Characteristics
The name indium is derived from the spectroscopic line characteristic of this element, the color indigo. It is a fusible, very soft and malleable silvery-white light metal. In chemical properties it is similar to aluminum and gallium, in appearance it is similar to zinc.

Production
First, an indium circle is made - an ingot of cylindrical shape, which is further subjected to pressure treatment. It is made from Indium grade In00 (99.999% pure indium) Ø 21-25 mm and length 50-70 mm or Ø 22-24 mm and length 63-67 mm. Minor defects on the surface of the wheel are permissible within the limits specified by the standard. Where there is a fracture, the specimen is free of foreign matter and voids.
Applications
It is impossible to imagine modern radio engineering without indium wire. In semiconductor microelectronics it is used along with germanium and silicon. It is also used as a component of fusible solders and alloys. High adhesion of such wire allows soldering, for example, metal with glass. It is used for sealing gaskets when sealing spacecrafts and elementary particle gas pedals. The significant thermal neutron capture cross-section of this wire is important in nuclear power engineering. Indium wire and ribbon are indispensable in electroplating for electrode fabrication. Electrochemical interaction of indium with mercury oxide is used in high-energy batteries. Indium is five times softer than lead. Indium wire is used for spraying between moving parts of machinery to reduce friction. For example, the skirts of aluminum pistons of diesel engines are coated, which significantly reduces their wear. Lead-silver bearings with indium sputtering, which is applied in a vacuum, are widespread.
Storage
Indium wire is kept indoors in the manufacturer's packaging, isolated from contact with aggressive environments and dust. The warranty shelf life is 5 years in the original packaging.
