Research on Developing High Properties Aluminum Alloy for Aeronautic Structure

The dynamic and progress tendency of high properties aluminum alloy for aeronautic structure are analyzed in this paper.It is mostly means improving capability of aluminum alloy structural materials that adjust component,depress content of impurity improve process of manufacture.It is mostly tendency developing aviation aluminum alloy that R＆ D of super high strength aluminum alloy,high strength and tenacity aluminum alloy,Al－ Li alloy,high strength and tefractory aluminum alloy,high strength and super plastic alloy as well as compound materials.
