Abstract
Lightweight metal containers are formed from high-strength metal alloys by impact extrusion of a cup-shaped container having a substantially larger diameter than the finished container, drawing and wall ironing the extruded container to reduce its diameter and wall thickness while increasing the height of the container to the appropriate diameter, wall thickness and height.
