Aluminum foil is widely used in electrolytic capacitor material; Insulation materials for buildings, vehicles, ships, houses, etc.; It can also be used as decorative gold and silver thread

Copper foil is a negative electrolytic material, which is a continuous metal at the bottom of the circuit board. It is characterized by being very thin and can be a PCB conductor. Generally speaking, it is glued to the insulation layer above, through the printing process to form a corresponding protective layer on the surface, and then through corrosion to form a circuit pattern

Copper strip is a kind of metal components, the product specifications are 0.1 ~ 3×50 ~ 250mm various states of copper strip products, mainly used for the production of electrical components, lamp caps, battery caps, buttons, seals, connectors, mainly used as electrical conductivity, thermal conductivity, corrosion resistance equipment. Such as electrical components, switches, gaskets, gaskets, electric vacuum devices, radiators, conductive base materials and automotive water tanks, heat sinks, cylinder sheets and other parts.
