Abstract: Briefly describes the classification of 2××× series aluminum alloys, the roles of various additive elements, and the selection criteria for process parameters such as deformation temperature, deformation rate, and deformation degree during forging. The paper mainly discusses the influence of raw material selection, forging process and heat treatment process of large forgings of 2××× series aluminum alloy on microstructure and mechanical properties. The problems faced in the forming of large and complex forgings of 2××× series aluminum alloys are pointed out, and specific suggestions are put forward.
