Indium/Silver Alloy Foil (Light Tight) (In97/Ag 3)

Formula: In 97/Ag 3
Form: Foil (Light Tight)
Material: Indium/Silver Alloy
Commodity: Alloys
Thickness: 0.3mm
Light Tight: Light Tight
Goodfellow's Indium/Silver Alloy Foil (Light Tight) (In97/Ag 3) is a versatile foil product with unique properties. The indium/silver alloy combines the ductility and malleability of indium with the increased hardness and strength of silver. This results in a foil that is highly flexible yet more durable than pure indium foil. Potential applications of this light-blocking foil include shielding sensitive optics and sensors from stray light, as well as providing a reflective coating for scientific instrumentation operating in the infrared spectrum. With its tailored material properties, Goodfellow's indium/silver alloy foil enables solutions for a range of research and industrial needs.
