Abstract

The alloy X2096 (Al-Cu-Li-Mg-Ag-Zr) is a member of the Weldalite® 049 family of alloys. The alloy is an ingot metallurgy low-density, high strength and toughness, weldable alloy designed to achieve the strength of 7075T6 combined with the stress corrosion cracking resistance of 7010/7050T7x. Unlike the previous generation Al-Li alloy 8090, X2096 is reported to achieve high strengths without the necessity to cold work prior to ageing. The composition of this alloy has been optimised for the maximum lithium content without forming □' during artificial ageing. The forgeability of X2096 has been assessed by manufacturing a conventional closed die forging and subjecting the resulting parts to mechanical testing including tensile, fracture toughness and stress corrosion cracking tests. These observations are compared to properties from the same forging made from the established Al-Zn-Mg-Cu alloy 7010.
