Patent ID: 7353980

Claim:
A process for producing aluminum-containing honeycomb bodies, which process comprises the following steps: providing at least partially structured metal foils based on aluminum; at least one of stacking or winding the at least partially structured metal foils to form a honeycomb structure with passages having an open end face; selecting a brazing material from the group consisting of zinc-based brazing material and aluminum/silicon-based brazing material; on using a zinc-based brazing material, heating the metal foils with at least one radiant heater from the open end face of the passages, to heat the honeycomb structure, at least in a subregion, and cause the at least one subregion, after approximately 2 seconds to approximately 15 seconds, to have a temperature of approximately 450Â° C. to approximately 530Â° C.; on using a aluminum/silicon-based brazing material, heating the metal foils with at least one radiant heater from the open end face of the passages, to heat the honeycomb structure, at least in a subregion, and cause the at least one subregion, after approximately 2 seconds to approximately 15 seconds, to have a temperature of approximately 560Â° C. to approximately 600Â° C.; and connecting the metal foils to one another by technical joining in the at least one subregion.
