Description of Aluminum Lithium Alloy

Aluminum Lithium Alloy 1460 Al-Li alloys are primarily of interest to the aerospace industry for their weight advantage. Lithium is the lightest metal element in the world. The addition of lithium to aluminum reduces the specific gravity of the alloy and increases the stiffness while still maintaining high strength, good corrosion resistance and fatigue resistance, and suitable ductility.

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.
