This is an excellent heat dissipation material that is widely used in modern heat dissipation. Most of the industry uses 6063 T5 high quality aluminum material. Its purity can reach more than 98%. Its strong thermal conductivity, low density, and low price are the major manufacturers. Favor. According to the thermal resistance values of Intel and AMD CPUs and their heat generation considerations, aluminum extrusion manufacturers formulate corresponding molds to heat aluminum ingots to a certain temperature to change their physical form.
