Indium Metal :
Indium Metal is extracted from indium bearing based metal ores and refined to various grades in high volume utilizing state of the art SPC controlled refining technologies. Rigorous quality standards and advanced analytical instrumentation such as ICP and GDMS, insures consistent product quality lot to lot.
General Properties and Applications of Commercial Grade Indium
Indium is versatile metal with unique physical properties. Following a some of the unique properties of indium and a sampling of innovative applications for the metal:
-Indium has a lot metlgin point of 157 degrees C but a high boiling point of 2080 degrees C; one of the highest liquidus temperature range of any metal.
-Indium has a low vapor pressure making it ideal for use in high vacuum applications.
-Indium is soft, pliable and malleable, even down to cryogenic temperatures approaching absolute zero. It will form a hermetic gasket seal between two mating metal parts. Being soft, indium will deform and fill
in the microstructure of two mating parts, pressed together using moderate pressure. Similarly, indium can be used as an efficient thermal conductive interface in electronics.
-Indium has relatively low toxicity.
-Indium is a bright shiny metal that forms a thin (80-100 angstroms) protective oxide layer. It is used as a decorative trim coating metallization on plastics used in appliance and automobile trim.
-Indium will cold weld to itself, useful for bonding parts or assemblies together.
-Indium effectively reduces the melting point in solder alloys and fusible alloys.
-Indium in small percentages improves the thermal fatigue performance of solders used in electronics assembly.
-Indium will bond to glass quartz and certain ceramics and oxides.
-Indium will compensate for differing thermal coefficients of expansion of mating parts.
-Used in small amounts, indium will harden certain metals and alloys; hardens gold used in electronics and dental alloys.
-Indium coatings will provide lubricity in sleeve bearings such as used in aircraft pison engines and industrial machinery.
-Indium is a neutron absorber and is used in radiation detection badges.

Fusible Alloys include a group of binary, ternary, quaternary, and quinary alloys containing Bismuth, lead, tin, cadmium and indium. The term fusible alloy refers to any of the more than 100 white-metal alloys that melt at relatively low temperatures.
Fusible alloys are materials that melt at less than 300F, well below the melting point of Tin-lead eutectic solders. The major component of fusible alloys is bismuth. Besides producing low melting point, bismuth also gives these materials the unique characteristic of expanding on freezing. This expansion, which can continue for hours or even days after freezing, has proven to be a useful property in many processes.
Fusible Alloys are classified as either eutectic or non-eutectic. In eutectic alloys, the melting point coincides with the freezing point. Non- eutectic alloys exhibit a range between the melting and freezing point in which the material is "mushy" or "pasty".
Fusible Alloys are used for lens blocking and tube bending, for anchoring chicks and fixtures and for mounting thin sections such as gas turbine blades for machining. The eutectic fusible alloys, which can be tailored to give s specific melting point, find applications in temperature control devices and in fire protection devices. Details… -
