The density of indium foil typically ranges from approximately 7.3 to 7.4 grams per cubic centimeter (g/cm³), for the typical 4N indium foil, 7.31g/cm3 is the density at the temprature of 25 degrees. However, slight variations in density may occur depending on factors such as the purity of the indium and the manufacturing process used to produce the foil.
Indium foil Thermal Interface Material (TIM) stands out in its ability to operate effectively even in cryogenic environments. Retaining its malleability, it serves as a reliable seal. Crafted from 99.998% pure Indium, this flexible foil TIM boasts exceptional properties:
Withstanding temperatures ranging from -270°C to 155°C.
Exhibiting a superior thermal conductivity exceeding most thermal greases and sheets by over tenfold (84 w/m-k).
Guaranteed safe for deployment in vacuum conditions, devoid of any outgassing risks.
Maintaining its malleable nature at cryogenic temperatures.
Easily customizable with simple tools like scissors, an X-acto knife, or a razor.
Frequently utilized in applications bridging laser diodes with their housing or heat sinks.
The Indium Foil utilized as a thermal interface is easily manageable with pick and place tools due to excellent ductility and malleability. These characteristics make it highly pliable and adaptable to various applications, allowing for precise positioning and placement within electronic devices or heat management systems. Whether it’s conforming to irregular surfaces or being accurately maneuvered into tight spaces, the Indium Foil’s flexibility ensures efficient and reliable installation processes. This versatility contributes to streamlined manufacturing workflows and enhances the overall effectiveness of thermal management solutions in a wide range of industries, from electronics to aerospace.
