Cobalt/Chromium/Tungsten/Nickel/Iron/Manganese Alloy Foil (Light Tight) (Co50/Cr20/W15/Ni10/Fe 3/Mn 2)
Cobalt/Chromium/Tungsten/Nickel/Iron/Manganese Alloy Foil (Light Tight) (Co50/Cr20/W15/Ni10/Fe3/Mn2) is a precision-engineered, pinhole-free rolled foil designed for high-performance applications requiring exceptional wear resistance, thermal stability, and complete light shielding. Its high cobalt and chromium content provides outstanding oxidation and corrosion resistance, tungsten enhances hardness and high-temperature performance, and nickel, iron, and manganese contribute ductility and toughness. This alloy foil is used in aerospace, electronics, and vacuum technology, with specific roles in high-vacuum seals, radiation shielding layers, and precision optical baffles. Its light-tight property ensures zero light transmission, critical in sensitive optical instrumentation and photonic experiments. In research, it serves as a controlled substrate for thin-film deposition and as a shielding layer in high-energy experiments. Industrially, it is valued for combining mechanical integrity, environmental resilience, and optical opacity in one versatile material.
