Iron/Nickel Alloy Foil (Fe58/Ni42)

Formula: Fe 58/Ni 42
Form: Foil/Film/Sheet
Material: Iron/Nickel Alloy
Commodity: Alloys
Iron/Nickel Alloy Foil (Fe58/Ni42) is an alloy foil produced by Goodfellow within their range of metal alloy foils. The foil exhibits properties like high permeability, relatively low coercivity, and corrosion resistance. Applications of the Fe58/Ni42 foil include magnetic shielding for sensitive electrical components and use as a construction material for chemical process equipment to withstand corrosion. At just 42% nickel content, the foil achieves useful magnetic and corrosion resistant properties while minimizing raw material costs.
