Nickel/Iron/Molybdenum Alloy Foil (Light Tight) (Ni80/Fe15.5/Mo4.5)

Nickel Iron Molybdenum Alloy Foil Light Tight (Ni80/Fe15.5/Mo4.5) combines the soft magnetic behavior of Ni–Fe alloys with molybdenum’s enhancement of permeability and reduction of core losses, alongside a pinhole-free surface for full light blocking. This composition provides excellent corrosion resistance, low magnetic hysteresis, and thermal stability, making it ideal for optical shielding, precision electromagnetic devices, and high-sensitivity sensors. Industries including aerospace, electronics, and microscopy use it in shielding enclosures, light-tight optical barriers, and magnetic circuit elements. Applications include electromagnetic compatibility housings, high-performance optical apertures, and sensor shielding in vacuum environments. In research, the material’s combined magnetic, optical, and structural characteristics support advanced studies in magnetic shielding effectiveness and precision optical control, making it invaluable in both cutting-edge technology and experimental setups.
