Graphite-aluminium composite is an in-plane high thermal conductivity, low coefficient of thermal expansion, lightweight thermal conductivity composite. It is composed of highly oriented natural flake graphite powder and aluminium matrix. The final product is a graphite-aluminium structure fully clad in aluminium alloy. Graphite-aluminium composite material is suitable for thermal conductivity components of homogeneous substrate, such as heat dissipation fins, homogeneous substrate, etc., to avoid the shortcomings of low longitudinal thermal conductivity as far as possible, and maximize the play of its high thermal conductivity within the surface.
