• Aluminum- Lithium Alloy (Al- Li) Description:

1) Al-Li alloys are a series of alloys of aluminium and lithium, often also including copper and zirconium. Since lithium is the least dense elemental metal, these alloys are significantly less dense than aluminium. Commercial Al-Li alloys contain up to 2.45 wt% lithium.

2) Lithium reduces density and increases stiffness when alloyed with aluminum. With proper alloy design, aluminum- lithium alloys can have exceptional combinations of strength and toughness.

3) Commercial aluminum-lithium (Al- Li) alloys are targeted as advanced materials for aerospace technology and to reduce the weight of U.S. Department of Defense systems primarily because of their low density, high specific modulus, and excellent fatigue and cryogenic toughness properties.

4) The principal disadvantages of peak-strength aluminum-lithium alloys are reduced ductility and fracture toughness in the short transverse direction, anisotropy of in-plane properties, the need for cold work to attain peak properties, and accelerated fatigue crack extension rates when cracks are micro structurally small.
