Abstract
The weldability of alloys of the system Al-Cu-Li is studied and promising alloyingranges are established for weldable alloys: 5.5-6.5% Cu, 0.8-1.4% LI and 2.5-3.5%Cu, 1.9-2.5% Li. The positive effect of adding small amounts of scandium on theweddability and mechanical properties of alloys of the system Al-Cu-Li is demonstrated.Properties at normal and cryogenic temperatures are given for a new weldablealloy 1460.
