| With the advantages of low density, high strength, high electrical/thermal conductivity and ease of processing, aluminum alloys have gained extensive application to automotive, electronics and communication industries by serving as the structural and thermal-dissipation material. However, the thermal-dissipation ability of the metallic materials which mainly consist of aluminum confront severe challenges from the swift development of equipment toward integration, miniaturization, light weight and high po-wer. This paper reviews the research and development status of the aluminum alloys and aluminum matrix composites for thermal dissipation, provides elaborate descriptions about the thermal conductive mechanism of aluminum alloys, and the effects of alloy composition and processing technique on the product’s thermal conductivity, and moreover, analyzes the thermal characteristics of aluminum matrix composites such as Al-Si, Al-SiC, Al-diamond, Al-graphite flake/carbon nanotube, etc. Finally, we briefly summarize the unresolved issues and future development directions for this species of crucial materials for industry. |
