Basic Information
Custom Rare Metal manufactures high purity Indium Alloy Foils in many thicknesses and sizes for heat dissipation, vacuum seal and other industrial uses. Most alloy foils are produced from cast ingots and thickness can range from 0.01mm to approximately 6mm for all metal alloys. Piece sizes are available up to approximately 450mm maximum width. Maximum lengths of about 1000mm can be obtained with a nominal thickness between about 0.01mm and 3mm for thin film deposition on glass or metal substrates.
Available Forms
- Indium Foils
- Indium Pad
- Indium Disc
- Indium Seal
- Indium Tin Foil
- Indium Silver Foil
Also, we produce Indium as rod, pellets, powder, bar, granules, and other alloys, as nanoparticles and in compound forms, such as oxide. Indium alloy foils may be purchased in bulk or small quantity.

Indium Alloy Foil Applications
- Ideal material for creating cryogenic vacuum seals
- New and popular Thermal Interface Material TIM
Superior high and low temperature resistance, withstanding temperatures from -273 to 155°C - Thermal conductivity up to 80 w/m-k, 10 times greater than most thermal greases and metal thermal sheets
- Safe for use in vacuum environments, no air leakage
- Stays malleable and deformable at cryogenic temperatures
- Able to be cut to desired size with scissors or an X-acto knife or razor
Widely used between the diode and the heat sink - Suitable for chip cooling and chip packaging
- Available for Server Liquid-Cooled Data Centers and Cryogenic Superconductivity.

Customization Production
Please specify desired composition, size or form when requesting pricing. We will let you have NDA and quotation project
Even for only 1 piece, it is available for you as well. If there’s no stock, it takes around 3-5 working days to finish the production, but some types need customize mould then the lead time would be extra 5 working days.
Highlights
01
High thermal conductivity
- No oil or oxidization on the surface, accelerating heat conduction to achieve rapid heat dissipation.
- Good wettability ensures full filling of the interface
02
Good insulation
Thermal conductive sheet ensures no leakage of current, thus avoiding safety risks due to short-circuiting
03
Various forms, flexible and customizable
Single-sided and double-sided rhombus, dot mesh shaped, multi-layer composite and other heat conducting sheets.
Packaging, Transport and Storage
- Packaging: each alloy foil packed in vacuum plastic bag, with carton boxes outer package. Clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage before transit or during transport.
- Transportation: by Fedex, DHL, UPS with door to door delivery, by Air for urgent order and by Sea for bulk order.
- Storage: store in a dry, clean environment to avoid damage and pollution.
