Formula: Cr
Form: Foil/Film/Sheet
Material: Chromium
CAS Number: 7440-47-3
Commodity: Metals
Chromium foil (Cr foil), known for its oxidation resistance, hardness, and electrical conductivity, plays an important role in semiconductor fabrication, where it is used for etching masks and thin-film coatings. Its high-temperature stability makes it ideal for thermal shielding in vacuum furnaces and automotive exhaust systems, where extreme conditions require robust materials. In optics laboratories, chromium foil's reflectivity is leveraged for laser mirrors, infrared sensors, and precision optical coatings, ensuring high-performance light control. Additionally, its corrosion resistance supports catalytic research and material synthesis, making it a crucial component in laboratories, R&D facilities, and industrial processing applications. Chromium foil is also used in sputtering targets for thin-film deposition and explored for biocompatible coatings in specialized medical and research settings.
