The indium wire In-0 - indium N3
The name indium is derived from the spectroscopic lines, which are typical for this item is Indigo. It is fusible, very soft and malleable silvery-white light metal. Chemical properties similar to aluminum and gallium, in appearance to zinc.

First produced indium circle — solid ingot of cylindrical shape, which is further subjected to pressure treatment. It is made from India brand Ин00 (indium 99.999% purity) Ø 21−25 mm and length 50 — 70 mm or Ø 22−24 mm and a length of 63 — 67 mm. On the surface of the range of acceptable minor defects, does not extend beyond the specified standard. Where there is a fracture, the sample does not contain foreign inclusions and voids.
Modern radio equipment it is impossible to imagine without indium wire. In semiconductor microelectronics, it is used along with germanium and silicon. And use it as a component of low-melting solders and alloys. High adhesion of such wire allows to solder, for example, metal with glass. It is used for sealing gaskets for sealing space vehicles and particle accelerators. A significant capture cross section for thermal neutrons such wire is important in nuclear power. Indium wire and strip irreplaceable in the electroforming in the manufacture of electrodes. Electrochemical interaction of indium with mercury oxide is used in high-energy batteries. Indium is five times softer than lead. Using indium wire to produce a coating between moving parts of machines to reduce friction. For example, cover the skirts of aluminum pistons for diesel engines that reduce wear and tear. Widespread lead-silver bearings with indium coating, which is applied under vacuum conditions.
Indium wire contain in the closed premises in the manufacturer’s packaging, insulating it from contact with aggressive media and dust. Warranty period of storage in original packaging 5 years.
