Thermal Management
Alloy systems that are liquid at room temperature have a high degree of thermal conductivity, far superior than ordinary non-metallic liquids. This allows for the use of these materials in specific heat-conducting applications, such as heat dissipation in sensitive components during operation, machining, and/or manufacturing.
Other advantages of these liquid alloy systems are their inherent electrical conductivity. Typical applications for these materials include thermostats, switches, barometers, heat transfer systems, and thermal cooling and heating designs.
Hermetic Sealing
Some sealing operations use pure indium and require no heat at all. The sealing process uses mechanical pressure to create the bond. The softness and malleability of indium, in addition to its ability to retain these characteristics at cryogenic temperatures, allows it to fill in imperfections in mating surfaces to create a hermetic seal.
Fusible Alloys
Low-temperature or fusible alloys are commonly used in a variety of safety devices where they are designed to melt at a peak temperature to initiate a process. Eye glass lens blocking is another application where low-temperature or fusible alloys work well. The lens is held in place using a block of the alloy, which is then easily removed with hot water.
