Silver Electrical Contacts are mainly used in contactors, switches, connectors, relays, and cross points in conductive circuits. Contact refers to the point of intersection where electronic appliances are disconnected and contacted when they are opened and closed.
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.
