Summary

The powder-metallurgical manufacture of aluminium foam is based on the steps: powder mixing, cold isostatic pressing, extruding, rolling and (if necessary) roll bonding. The expandable materials are therefore available in the form of rods, sheets or bonded sheet structures. Sandwich structures can be manufactured both by bonding with aluminium and with steel sheets. When the expandable semi-finished material is heated to temperatures above the liquidus limit and the decomposition temperature of the foaming agent, the formation of foam begins. Structures of many different types can be produced using appropriate expansion dies. Possible uses would be volume bodies for energy dissipators, aluminium foam sandwiches with foam core or simple foam sheets for various applications in the engineering, automotive, architecture or design fields.
