Indium Foil Suppliers

INDIUM FOIL is composed primarily of pure indium with minimal impurities to ensure strength and superior flexibility. The material’s purity affects the foil’s qualities, with higher purity levels enhancing specific properties. Eco-friendly and fusible, indium has low melting and higher boiling points, facilitating its diffusion into other metals to form beneficial alloys. These foils serve crucial roles in high-temperature and cryogenic applications by acting as heat sinks, effectively dissipating excess heat to prevent overheating. In water, indium foils resist corrosion, and in air, they resist oxidation, though they are less resistant to thermal stress and acids.

Consequently, they are not recommended for use with acid chemicals or in high-temperature environments. Indium foils also find applications in nuclear facilities due to their neutron capture capabilities, and they are utilized to produce mirror coatings by vapour deposition on glass. As a trusted indium foil supplier, Special Metals ensures top-quality products to meet your specific requirements.

What is indium used for?

Indium is a versatile metal used in various applications due to its unique properties, low melting points, and excellent conductivity. One significant use of indium is in producing indium foil, used in high-temperature and cryogenic applications as a heat sink to soak and scatter excess heat, preventing overheating. Additionally, due to its neutron capture capability, indium foil is employed in low thermal conductivity environments, corrosive media, and nuclear facilities. The foil’s malleability and fusibility make it ideal for creating thin, precise layers for specialized industrial uses, including mirror coatings by vapour deposition on glass.
