aluminium extrusion fin profile

In short, aluminum extrusion technology involves heating aluminum ingots to a high temperature of approximately 520-540 degrees Celsius, and then passing high-pressure aluminum liquid through an extrusion mold with grooves to produce an initial heat sink. After cutting and slotting the initial heat sink, it becomes a regular heat sink. Aluminum extrusion technology is relatively easy to implement and has relatively low equipment costs. In recent years, it has also been widely used in the low-end market. The commonly used aluminum extrusion material is AA6063, which has good thermal conductivity (about 160-180W/m.k) and processability. However, due to material limitations, the thickness to length ratio of the fins cannot exceed 1:18, making it difficult to increase the heat dissipation area in a limited space. Therefore, the heat dissipation effect of aluminum extruded fins is relatively poor, making it difficult to meet the increasing demand for high-frequency CPUs. Our aluminum fin is used 6000series aluminum in Metals And Alloys, which is use the surface treatment of powder coat paint. and we provide customization service like cnc aluminum，casting profiles and die cast metal. based on your drawing.
