METAL CARRIER COMPOSED OF THIN METALLIC FOIL FOR CLEANING EXHAUST GAS OF AUTOMOBILE AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To improve the erosion resistance and oxidation resistance of a metallic carrier formed of corrugated foil and flat foil consisting of thin metallic foil and to allow the carrier to exhibit excellent durability. SOLUTION: The brazing part 3 of =4 times the foil thickness in the maximum thickness of brazing in the brazing part 3 of the foils to each other of a honeycomb body constituted by brazing the corrugated metallic foil and flat foil of 1 of 8 to 25 m in thickness is so formed as to occupy =70% of the entire brazing part 3, by which the strength of the brazing part 3 is maintained and in addition, the form as the honeycomb may be maintained even if the brazing part 3 is melted by an accidental fire.
