摘要：
An aluminum based alloy useful in aircraft and airframe structures which has low density and consists essentially of the following formula:Mg.sub.a Li.sub.b Zn.sub.c Ag.sub.d Al.sub.balwherein a ranges from 0.5 to 10%, b ranges from 0.5 to 3.0%, c ranges from 0.1 to 5.0%, d ranges from 0.1 to 2.0%, and bal indicates the balance of the alloy is aluminum, with the proviso that the total amount of alloying elements cannot exceed 12.0%, with the further proviso that when a ranges from 7.0 to 10.0%, b cannot exceed 2.5% and c cannot exceed 2.0%.
