Copper/Nickel Alloy Coils (Cu70/Ni30) are a versatile product in our extensive range of metal foils. We offer them in 13 variations, including thickness from 0.025mm to 0.5mm and widths from 5mm to 305mm. Their alloy composition combines the ductility and conductivity of copper with the corrosion resistance of nickel. These properties make them ideal for a wide range of applications, including electrical contacts, resistance heating elements and shields against electromagnetic interference. With numerous options available, our Copper/Nickel Alloy Coils enable prototypes and small-scale production across industries.
