Aluminum Lithium (Al-Li) Alloy Weldalite 049 Description
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. Aluminum Lithium (Al-Li) Alloy Weldalite 049 is generally joined by friction stir welding.
