Abstract

Use of a metallic partial composite laminate body which is provided with a large number of axially extending channels and is made by expanding a large number of layers, as support for exhaust gas catalysts of Otto-engines in which the mutually oppositely disposed non-inflated edge portions of the expanded partial composite laminate body serve for a particularly stable fastening of the support in the catalyst housing.
