As a key component in modern industrial heat dissipation systems, heat-dissipating aluminum sheets, with the unique properties of aluminum alloy materials, have become the preferred solution for balancing efficiency, cost, and durability. Their core advantage stems from precise material proportioning—usually using aluminum alloys such as grades 1050 and 6061 as the base material. 1050 aluminum has high purity, with a thermal conductivity of over 220W/(m·K), making it suitable for precision electronic equipment that has strict requirements on heat dissipation efficiency; 6061, on the other hand, improves strength by adding magnesium and silicon elements, with a thermal conductivity of about 160W/(m·K), and is more suitable for industrial scenarios that need to take into account structural support.​

In terms of processing technology, heat-dissipating aluminum sheets integrate a variety of precision technologies. In addition to conventional cutting and stamping, the fin forming process forms dense heat-dissipating teeth through mechanical stretching or welding, increasing the heat dissipation efficiency per unit area by more than 30%; anodizing treatment forms an oxide film of 5-20μm on the surface, which not only enhances wear resistance but also strengthens heat radiation capacity through the porous structure, while endowing the aluminum sheets with various appearances such as black and silver to adapt to the design requirements of different equipment. For special scenarios, electrophoresis coating or chemical conversion treatment can also be carried out to further improve corrosion resistance and meet the use requirements of outdoor and humid environments.​

In terms of application scenarios, heat-dissipating aluminum sheets have an extremely wide range of adaptability. In the field of consumer electronics, it is the "cooling guard" for 5G base station power amplifiers and laptop CPUs. Through ultra-thin design (with a thickness of up to 0.3mm), it fits the surface of the chip to quickly conduct heat out; in new energy vehicles, the heat-dissipating aluminum sheet at the bottom of the battery pack cooperates with the water cooling system to control the working temperature of the battery cells within the ideal range of 25-40℃, ensuring battery life and safety; in industrial equipment, the heat dissipation modules of high-frequency motors and laser cutting machines rely on the combination of thick plates (5-20mm) and fins to cope with continuous high-temperature output. In addition, the customized service can process special structures such as irregular shapes and curved surfaces according to the 3D model of the equipment, ensuring a perfect fit with the heat dissipation components and avoiding the increase in thermal resistance caused by assembly gaps.​ Compared with copper heat-dissipating parts, heat-dissipating aluminum sheets are more than 40% lighter in weight and about 50% lower in cost, and can achieve close heat dissipation effects through reasonable design, making them an ideal choice that takes both economy and practicality into account.​
