Graphite copper mesh, also known as graphite composite copper mesh, is mainly a thermal conductive material used for external thermal conduction and heat dissipation of heating units; It can also be used as an electrode material. Its composition is generally natural graphite and copper mesh, with a structure of graphite copper mesh graphite or graphite copper mesh. The graphite surface is visually gray black, and the copper surface is yellow (brass) or purplish red (purple copper). Short description: Graphite composite copper mesh is made by using special rolling technology to roll graphite powder onto both sides of the copper mesh. This ensures high thermal conductivity, enhances tensile strength, and also has an electromagnetic shielding effect. After being made into a ribbon, it can also serve as a heating element to provide heat to the product. Mainly used in mobile phones, computers, cameras, electric vehicles, and base stations.

Thin thickness, difficult to process copper with a thermal conductivity of 400 W/(m · K) below 0.075mm! High density! High cost! Aluminum has a thermal conductivity of 227W/(m · K) and a low density of only 2.7g/cm3, making it difficult to process! High cost! High interface thermal resistance and poor heat dissipation performance! Thermal conductive silicone is easy to process. a) It has a low thermal conductivity, only a few W/(m · K). b) It is used in large quantities, greatly increasing the weight and making maintenance difficult. The thermal conductivity of graphite composite copper mesh can reach 600W/(m · K). The thermal conductivity can still be further improved. The density is low, only about 2-2.5g/cm3, and it is soft and bendable. It is easy to process. The resistance of 30mm * 1mm specification is about 5 Ω/m.
