70/30 copper nickel With trace amounts of iron and manganese added for strength and corrosion resistance, foil is made up of 70% copper and 30% nickel. It provides exceptional resistance to erosion, stress corrosion cracking, and seawater corrosion. Excellent ductility and strength are ensured by the foil’s tensile strength of 350–550 MPa, yield strength of 150–260 MPa, and elongation of 30–40%. It is perfect for demanding industrial applications where stability and dependability are crucial because of its high density of 8.94 g/cm³ and good thermal and electrical conductivity.
