In the early 1980s, alloys of aluminium and lithium (typically BA 8090C) were introduced as possibly replacements for, especially, carbon fibre composites in aircraft structures. They had a significantly lower density than the conventional alloys — 2024 and 7075 — (Sg of 2.54 as opposed to 2.78) which could make a considerable contribution to weight saving. Aluminium-lithium alloys also had an increased stiffness over other aluminium alloys of similar strength. Conversely, they appear to be more ductile than the conventional alloys, as evidenced by the load-extension curves for simple lap shear joints [51]. 

The aluminium alloys most frequently encountered are the 2(X)0, 7000 and, occasionally, the 6000 ranges with 2024 and 7075 grades being the most common aluminium-lithium alloys such as 8090C are also used in special applications. 

We will limit our discussion to alloys in which the level of iron and silicon has been purposely increased (8011, 8021) and will not deal with special or experimental alloys such as aluminium-lithium alloys.
