Abstract
A manufacturing method for the production of aluminum-lithium alloys at low cost is disclosed which includes enclosing lithium with aluminum by means of a cold extrusion of pure lithium and melting the aluminum-sealed lithium ingots in an ambient atmospheric condition. The extrusion process can be simply performed in air as well as in an inert atmosphere at room temperature. The atmospheric melting of aluminum-lithium alloys is performed by immersing and agitating aluminum-sealed lithium ingots beneath the surface of molten aluminum with a graphite plunger.
