The standard scale of rolled Pure Copper Foil is (0.05～0.010) mm (thickness) × (40～600) mm (width), and the length is generally not less than 5000mm when supplied in coils. The conditions are soft and hard, and most of them are hard. Its characteristics are: fine arrangement, uniform function; high surface finish, good public service; single minimum thickness and width are restricted. Rolled copper foil can be divided into oxygen-free copper foil for electron tubes, oxygen-free copper foil and red copper foil according to chemical composition, and corrosion-resistant alloy copper foil with trace elements and heat-resistant alloy copper foil are added.
