ABSTRACT:
A process for producing a metallic layer includes forming structures at least in subregions of the metallic layer. The structures have corrugation troughs and corrugation peaks, an upper bearing surface formed at least in part from the peaks, and a lower bearing surface formed at least in part from the troughs. The metallic layer is formed with at least a first region having a first thickness and a second region having a second thickness, different than the first thickness. The structures are formed, in longitudinal direction, independently of the thickness, with at least one of the upper and lower bearing surfaces in the regions being substantially aligned in longitudinal direction in vicinity of at least one of the peaks and the troughs. A metallic layer with regions of varying material thickness and a honeycomb body produced at least partly from such metallic layers, are also provided.
