Summary:

This book succeeds in providing a comprehensive and detailed treatment of all aspects of extrusion, with special emphasis on the latest advanced technology. Among the extruded metals covered are aluminum, lead, tin, magnesium, zinc, copper, titanium, zirconium, beryllium, uranium, nickel and steel. Processes discussed include direct and indirect extrusion, cable sheathing by extrusion, hydrostatic extrusion, cladding by extrusion, and special technology for extruding various metals. Also discussed are stresses in extrusion, economic aspects, and future developments.
