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.
Claims1
A method for manufacturing an exhaust gas body made of thin metal foil, comprising:
- a step of forming a honeycomb body in which 10˜25 μm thick corrugated metal foil and flat metal foil are joined by brazed joints using a brazing powder;
- the brazing powder having a particle diameter not greater than 4 times the thickness of the metal foil constituting the honeycomb body.
