Innovative Materials Increase Sustainability in the Factory

To produce aluminum foams, an aluminum alloy powder and a blowing agent powder are mixed together and usually pre-compacted by axial pressing. They are then compacted into foamable strands by extrusion molding. To produce aluminum foam sandwiches, cut foamable aluminum strands are placed between two cover sheets positioned at a distance from each other. During the subsequent heat treatment, the foamable aluminum expands many times over. The resulting foam bonds with the two cover sheets to form a sandwich. (Image:VDW) arrow back Image Zoom
