Sheet metal layers of a layer-like configuration with rolled-on brazing material and process for the production of a honeycomb body therefrom

Abstract

A sheet metal layer of a layer-like configuration with rolled-on brazing material and a process for producing a honeycomb body by stacking and/or winding sheet metal layers made of a layered material. At least a part of sheet metal layers for honeycomb bodies have a structure forming channels through which a fluid can flow. At least part of the sheet metal layers is formed initially of a layered material with at least one layer of chromium-containing steel and at least one mainly aluminum-containing layer, that are homogenized to a large extent during a subsequent heat treatment. The layered material is provided with at least one additional layer made of brazing material when it is produced by rolling, so that during a subsequent heat treatment at least parts of contact locations between the sheet metal layers are joined by brazing. The brazing material is preferably located only in a partial area of a bonding layer of the layered material, preferably in the form of brazing strips that extend along at least one edge.
