Evanohm® Foil

Formula: Ni 75/Cr20/Al 2.5/Cu 2.5

Form: Foil/Film/Sheet

Material: Evanohm®

Commodity: Alloys

Evanohm® Foil is a nickel-chromium-aluminum-copper alloy foil supplied by Goodfellow in 16 different variations of thicknesses and temper to suit a variety of applications. This alloy combines high conductivity with good corrosion resistance, making it well suited as a low-contact resistance material in electrical components. Evanohm® Foil is also used for gaskets, shields and seals in aerospace, automotive and marine environments where its strength and corrosion performance are valued.
