Heat-Transfer Foil
Made of indium, this foil is more thermally conductive than thermal interface materials (TIMs) made of plastic. By efficiently pulling heat away from components that produce heat, such as CPUs, this foil lets you use smaller forced cooling systems to extend battery life. It’s also softer and more ductile than paste and putty, covering surfaces better to minimize airflow gaps and increase heat flow. Unlike paste and grease, this foil won’t leach out from between surfaces over time, nor will it dry out and lose effectiveness. It’s clean, easy to install and reposition, and requires no surface preparation. Foil is corrosion resistant and doesn’t need special storage.
Foil with 48% tin has greater tensile and shear strength than foil without tin, but is less thermally conductive.

Gold Foil
- Hardness: Rockwell B57 (Soft)
Since it’s thin and easy to cut, as well as highly conductive and corrosion resistant, this 99.99% pure gold foil is often used to plate electrical connectors that are exposed to the air. It’s also good for making parts that stay accurate in extreme environments because it has a high melting point, low thermal resistance, and won’t oxidize. An alternative to platinum, gold is more conductive, but has a lower melting point. Use it to make gaskets, even for high-vacuum applications, since it is soft enough to create a good seal when pressed between two flanges, but won’t damage the flanges so you can reuse them.

Ultra High-Temperature Molybdenum Foil
- Hardness:
1/2" Width: Rockwell C59 (Very Hard)
6" and 12" Width: Rockwell C19 (Medium)
Thin and easy-to-cut, this 99.95% pure molybdenum foil is often used in parts that process molten glass, heat shields in furnaces, and as filament supports in high-intensity light bulbs. Also known as refractory metal, it has a higher melting point than most metal. Molybdenum is roughly nine times more thermally conductive than Kovar nickel alloy, so heat passes through and moves away from the material quickly. It also has a low coefficient of thermal expansion, about half that of most steel, which means it won’t deform when exposed to an increase in temperature. However, molybdenum is denser than Kovar nickel alloy and steel. Known for conducting heat and electricity better than tantalum and platinum, it’s often used as semiconductors in motors and power supplies and parts in solar cells.
This material resists oxidation at temperatures below 750° F but will rapidly oxidize when exposed to air above 1400° F, making it ideal for high temperature vacuum environments. It also resists corrosion from acids as well as molten materials such as metal, alloys, and glass compounds. However, it will corrode from alkalis when it starts to oxidize.

Platinum Foil
- Hardness: Rockwell B97 (Medium)
Thin and easy to cut, use this 99.95% pure platinum foil in labs and electronics production. It won’t oxidize, won’t corrode in most environments, and has low thermal and electrical resistance. Platinum is often used to make gaskets, even in high-vacuum applications, because it’s soft enough to create a good seal when pressed between two flanges, but won’t damage the flanges so you can reuse them. It also works for high temperatures because it has a higher melting point than gold and other sealing materials.

Tantalum Foil
- Hardness: Rockwell C69 (Ultra Hard)
Thin and easy to cut, this 99.98% pure tantalum foil is good for coating heating elements that are used in furnaces. Harder than platinum and able to withstand higher temperatures than gold, it also resists corrosion and conducts heat.
