Abstract: The invention relates to a filter having a layer which is permeable to a medium to be filtered, comprising at least one nonwoven part, wherein the nonwoven part withstands higher mechanical loads. According to the invention the layer comprises, in addition to the nonwoven part, at least one sheet-like support part connected to at least one sub-region of at least one side of the nonwoven part.

Abstract: To achieve the object of providing a method by which the disadvantages entailed in the production of components made from materials that contain aluminum are avoided, a method for alloying aluminum to form components is described, the alloying of aluminum taking place by adding an aluminum-containing material, the component being surrounded by at least one means for receiving aluminum-containing material and the element that is formed in such a way being sintered. Preferably, the component is surrounded in at least one metal nonwoven material, aluminum foil being disposed between the nonwoven material and the component.
