The new material is an important foundation for the development of aerospace technology, aerospace technology and constantly on the material science put forward new questions and requirements. Aluminium lithium alloy is nearly ten years aviation metal materials in an area with rapid development.
Lithium is the lightest element. The lithium metal as alloy elements added to the metal aluminum, the formation of aluminum lithium alloy. After adding lithium metal, can reduce the proportion of alloy, increase the stiffness, while still maintaining high strength, good corrosion resistance and fatigue resistance, suitable for ductility. Because of these characteristics, a new alloy which has received extensive attention in aviation, aerospace and marine industry. It is because of the many advantages of this alloy, attracted many scientists to study it, aluminum lithium alloy development is rapidly developed.
