Metal catalyst carrier material for automobile exhaust gas purification

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal medium carrier material for automobile exhaust sag purification, which controls the content of Cr and Al in an alloy based on Fe-Cr-Al, and adds an appropriate amount of Ce rich misch metal. The present invention provides a metal catalyst carrier material for automobile exhaust gas purification that has excellent mechanical properties as well as comparable mechanical properties compared to conventional metal medium carrier materials by forming a metal catalyst carrier material. The present invention for achieving the above object is an alloy composed of Cr :: 18-30%, Al: 3-7%, remainder: Fe and other unavoidable impurities in the metal carrier material for automobile exhaust gas purification The present invention relates to a metal catalyst carrier material for automobile exhaust gas purification, which is formed by adding 0.05-1.5% of cerium rich mismetal to the total weight of the alloy.
