NanoFoil^®

Indium Corporation manufactures NanoFoil^®, a nanotechnology material that delivers energy in a controlled and precise manner for joining, energetics and heating applications.

NanoFoil^® is a reactive multi-layer foil that provides instantaneous heat for a variety of applications in many industries (semiconductor, aerospace, automobile, electronics, biomedical and defense markets). NanoFoil^® is a predictable, controllable and affordable material that is industry accepted and proven to lower manufacturing costs while providing repeatable and reliable bonds and reactions.

Indium Corporation has scaled NanoFoil^® production to high volume in an ISO certified process and is committed to helping customers realize the technical and economic benefits NanoFoil^® provides.

This reactive multi-layer foil is fabricated by vapor-depositing thousands of alternating nanoscale layers of Aluminum (Al) and Nickel (Ni). When activated by a small pulse of local energy from electrical, optical or thermal sources, the foil reacts exothermically to precisely deliver localized heat up to temperatures of 1500°C in fractions (thousandths) of a second.

Traveling approximately eight meters per second, the reaction's rapid delivery coupled with its localized and versatile nature makes it ideal for many types of bonding and reaction initiation (energetics) applications.
