Copper plated graphite

Copper plated graphite is mainly a thermal conductive material used for external thermal conduction and heat dissipation of heating units; It can also be used as an electromagnetic shielding material. Its composition is generally artificial graphite and electroplated copper, with a structure of artificial graphite copper plating. The graphite surface is visually gray black, and the copper surface is purple red. Its thickness varies depending on the artificial graphite used, generally ranging from 0.027 to 0.07 mm. Graphite copper plating is a electroplating method that involves electroplating a layer of copper on the surface of graphite, which can replace traditional graphite attached copper foil, reduce the interfacial thermal resistance between the copper layer and graphite, increase thermal conductivity, and improve the tensile strength of graphite. Graphite can be selected from both natural and artificial graphite, and copper layers can also be of different thicknesses, which not only improves performance but also reduces the complexity of the production process and lowers costs. After copper plating on graphite, it can be applied in areas that require both good heat dissipation performance and shielding effect, or can replace traditional graphite sheets. It is mainly used in laptops, high-power LED lighting, flat panel displays, digital cameras, mobile phones, and personal assistant devices.
