ABSTRACT:
A metal-made carrier body, for carrying thereon an exhaust gas cleaning catalyst, comprises a honeycomb core structure composed of a sheet-like metal band and a corrugated metal band. As each of the metal bands, an inexpensive thin steel band which is plated with nickel and then with an aluminum coating and further processed by diffusive penetration treatment, is used. The metal-made carrier body is inexpensive and is excellently heat-resistant and corrosion-proof.
