Abstract
A metal foil substrate material with improved formability properties for catalytic converters and a method of making the material in which layers of ferritic stainless steel and aluminum are solid state metallurgically bonded together forming a composite material. Such composite material is further rolled to an intermediate foil gauge and then subjected to a thermal in situ reaction to form a resulting uniform solid solution foil material with superior high temperature corrosion resistance. This uniform solid solution material is then rolled to the final foil gauge.
