Abstract
A metal foil connection of first and second metal foils having a thickness of less than 0.05 mm includes a connecting point in which the metal foils are brazed to one another. The connecting point forms a wedge which is filled with brazing medium. A mass of the brazing medium, and a mass of sections of the metal foils which the brazing medium contacts in the wedge, have a given ratio. A honeycomb body, a brazing medium particle fraction and a method for manufacturing metal foil connections with a thickness of less than 50 micrometers, are also provided.
Claims4
A method for manufacturing a metal foil connection of first and second metal foils using metal foil-brazing medium particle fractions, the method which comprises:
- providing the first and second metal foils with a thickness of at most 0.03 mm;
- applying glue to the first and second metal foils;
- subsequently contacting the first and second metal foils with a first metal foil-brazing medium particle fraction in a first step, subsequently again contacting the first and second metal foils with a second metal foil-brazing medium particle fraction in a second step;
- and
- brazing the first and second metal foils together at a connecting point forming a wedge.
