ABSTRACT:
A method for manufacturing a metallic carrier base material of multi-layer structure, if desired accommodated in a cylindrical case, for maintaining a catalyst for exhaust gas purification, wherein a multi-layer body having a number of screen-like vent holes in an axial direction is formed by piling up alternatively the planar band material and corrugate band material made of thin steel strip, to furnish the contact portion, if desired, after inserting the multi-layer body into a cylindrical case. The multi-layer body or thus obtained composite is then treated by immersion processing in a molten aluminum bath.
