• Ideal for creating cryogenic vacuum seals.
• 99.995% Pure Indium based Thermal Interface Material TIM.
• Able to withstand temperatures from -273 to 155°C
• Thermal conductivity 10 times greater than most thermal greases and thermal sheets (84 w/m-k).
• Safe for use in vacuum environments, will not outgas.
• Stays malleable/deformable at cryogenic temperatures.
• Indium sheet can be cut to size with scissors or an X-acto knife or razor.
• It’s commonly used between laser diodes and produces excellent heatsinking between the diode and the heat sink.

1. Thermal Management: Indium sheets are widely used as thermal interface materials. Their excellent thermal conductivity and ability to conform to surfaces make them ideal for use in electronics where efficient heat transfer is critical.
2. Coatings and Thin Films: They are used in the production of coatings and thin films through processes like Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD). These applications are common in industries such as fuel cells and solar energy.
3. Sealing: Indium’s malleability makes it useful for creating high-vacuum seals and gasketing materials. This property is leveraged in the semiconductor and aerospace industries, where reliable sealing is paramount.
4. Solders: Indium Sheet is also used in the production of low-melting-point solders, which are crucial in electronics manufacturing. These solders help in creating strong bonds at lower temperatures, reducing the risk of thermal damage to components.
5. Thermal Interface Materials (TIMs): Indium Sheet is an effective thermal interface material, facilitating efficient heat transfer between components. It is used in CPUs, power electronics, and LED lighting systems to prevent overheating by dissipating heat​

Storage

To extend storage time and minimize surface oxidation, please strictly seal the indium foil in its original container, ensuring a relative humidity of 55% or lower and a temperature not exceeding 22 ° C. Indium foil can also be stored in an inert atmosphere, such as a nitrogen drying oven.

A NOTE OF CAUTION: Do not allow the freshly etched indium parts to come in contact with one another because they will cold weld to each other (sticks like contact cement).

Indium Recycling

The recycling of indium has important environmental significance and helps reduce the impact on the natural environment. Our company is willing to recycle used scraps. You can contact our technical team to conduct a preliminary recycling assessment through photos and videos. We will provide an assessment report to confirm whether your product can be recycled or not. If the assessment report passes , we can arrange the next procedure for receiving samples.
