  • Al-Cu-Li weld filler alloy, process for the preparation thereof and process for welding therewith
    Patent number: 5512241
    Abstract: Weld filler alloys comprising aluminum, copper, lithium and, optionally, silver are disclosed which possess significantly improved fabricability and weldability. The weld filler alloys are free of magnesium and can be easily drawn into weld wire that is useful for welding aluminum-base alloys. Weldments made with the filler alloys exhibit highly improved mechanical, physical and corrosion resistance properties. The weld filler alloys may be used to weld cryogenic containers for space launch vehicles and the like.
