Abstract: A process for recycling light metal parts with gas inclusions or non-metallic particles. In order to convert different waste products into high class products in a process-technically simple manner, without requiring cleaning/purifying of the used materials, that from at least one light metal part with gas inclusions and at least one light metal part with largely dense, non-metallic particles, a gas containing metal melt is produced and a metal melt is allowed to solidify at an under-pressure for at least sometime under formation of a light metal foam body.

Abstract: The invention relates to a method for producing a metal foam body, according to which a molten material containing gas is prepared and said molten material is left to solidify, thus forming a metal foam body. The aim of the invention is to produce high-quality metal foam bodies with a desired shape, without requiring complex equipment and whilst reducing the safety risk for the operating personnel. To achieve this, the material used is fused under atmospheric pressure and gas is simultaneously and/or subsequently introduced into the molten metal. The latter is then poured into a mold and is left to solidify, whereby the ambient pressure is reduced at least temporarily.
