ABSTRACT:
A metallic honeycomb body has an axial length, a partial volume covering at least 55% of the axial length, a radial dimension of at least 20 mm, an inflow end side and an outflow end side. The honeycomb body includes sheet-metal layers structured to permit a fluid to flow through the honeycomb body in a flow direction from the inflow end side to the outflow end side. The sheet-metal layers each have a surface area, partial regions and edges at the end sides. Each of the sheet-metal layers have a multiplicity of holes formed at least in the partial regions in the partial volume. Each of the holes have a hole surface area of between 1 and 120 mm2. The sheet-metal layer surface area in the partial volume is reduced by 10 to 80% by the holes as compared to a sheet-metal layer without holes. The partial volume is disposed at a distance from each of the end sides, preventing the holes from touching and from cutting through the edges of the end sides of the sheet-metal layers.
