Aluminium alloy materials occupy an important position in the aerospace field, and aerospace castings are developing into precision, thin-walled and lightweight materials with structural integration trends and high performance. Therefore, it is crucial to understand and master the manufacturing technology of large-scale aluminium alloy complex products. The casting process method has obvious advantages in the field of large-scale complex thin-walled products; on this basis, this paper systematically addresses the bottleneck problems of large-scale complex aluminium alloy castings in production and summarizes the current status of domestic and international research on large-scale aluminium alloy castings. With respect to the casting materials, melt treatment, heat treatment, microstructure regulation and casting production equipment and other levels of summary analysis of the current research situation for the development of high-performance, high-precision large aluminium alloy castings and applications can provide corresponding solutions. Finally, for the future development of large-scale aluminium alloy complex casting manufacturing technology, from the

perspective of existing applied materials and new high-strength aluminium alloys, an outlook is presented.
