Formula: Au 88/Ge 12
Form: Foil (Light Tight)
Material: Gold/Germanium Eutectic Alloy
Commodity: Precious Metals
Light Tight:
Light Tight
Gold/Germanium Eutectic Alloy Foil (Light Tight) (Au88/Ge12) is available in 5 variations of different dimensions and thicknesses. With excellent ductility and malleability, it’s used in applications requiring an opaque barrier to visible light transmission, such as blocking light for optical devices. This foil’s gold and germanium composition also provides high reflectivity in the infrared spectrum, making it useful for thermal radiation shielding. Especially as it can be formed into a variety of shapes and sizes for customized applications with proper handling.
