Abstract
A metal foil substrate material 50 for catalytic converters 54 and method of making the material in which layers (10, 12, 14) of ferritic stainless steel and aluminum are solid state metallurgically bonded together forming a composite material 24. Such composite material 24 is further rolled to the final foil gauge with no heat treatment and then subjected to a thermal in situ reaction to form a resulting uniform solid solution foil material 50 with superior high temperature corrosion resistance.
