Indium Disk - T 0.75mm Ø 10mm

Details

SKU: 1000000156 Product Code: IN00-FL-000168
Indium Disk provides excellent ductility, low melting point, and outstanding ability to wet and bond to a wide range of materials in a compact circular form. These properties make it indispensable for sealing, bonding, and heat transfer applications. Industries such as electronics, aerospace, and cryogenics employ indium disks in vacuum sealing gaskets, thermal interface layers, and hermetic seals for optical and electronic devices. Specific technologies include cryogenic sealing of superconducting systems, bonding in infrared optics, and pressure-sealing in high-vacuum chambers. Research applications explore its wetting behavior in microelectronics, development of low-temperature solders, and optimization of thin-film adhesion. The disk form ensures consistent geometry for reliable performance in precision assemblies. Its unique combination of softness, chemical stability, and conductivity makes indium disks critical for advancing scientific instrumentation and high-reliability industrial systems.
