7000 series high strength aluminum alloys have been widely used in aerospace field.However,due to its poor casting properties,the forming method is mainly adopted plastic deformation,such as rolling and extrusion.Forming products include mainly plates and profiles,while it is difficult to prepare parts with complex shapes.Liquid extrusion casting and semi-solid squeeze casting technology can provide a feasible approach for the casting and forming of 7000 series aluminum alloys and their composites.It is expected to achieve "casting instead of forging",becoming an important direction of the development of high strength aluminum alloy forming technology in recent years.The research progress in squeeze casting 7000 series aluminum alloys and their composites was described,and the current problems were presented.Then the development direction was pointed out.
