Iron/Nickel Alloy Foil (Light Tight) (Fe55/Ni45)

Iron/nickel alloy foil (Fe55/Ni45) is a light tight alloy foil within Goodfellow's range of metal foils. This foil has high permeability and saturation induction, making it useful for magnetic shielding. It also has good ductility and corrosion resistance. Applications of this alloy foil include shielding for sensitive electrical components, gaskets, and seals. The 55% iron and 45% nickel composition provides an optimal balance of magnetic and mechanical properties for fabricated parts and precision components.
