  • CATALYTIC CONVERTERS-METAL FOIL MATERIAL FOR USE THERIN, AND A METHOD OF MAKING THE MATERIAL
    Publication number: 20020012601
    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.
    Type: Application
    Filed: May 26, 1999

  • Substrate for an electrical circuit system and a circuit system using that substrate
    Patent number: 5055967
    Abstract: A substrate is provided for mounting semiconductor devices and comprises an electrically conductive circuit layer, a base layer of an aluminum metal material, and an electrically insulating hard coating dielectric layer of amorphous aluminum oxide which is directly adherent to the base layer for mounting the electrically conductive circuit layer thereon.

  • Method for forming memory discs by forging
    Patent number: 4711115
    Abstract: A flat, smooth material, e.g., metal sheet, suitable for use as a disc substrate for applying a recording media thereto for data storage devices, and a method of making same, are disclosed. The flat and smooth substrate is formed by applying sufficient pressure to opposite surfaces of the material to achieve the desired flatness and smoothness prior to finishing. Subsequent finishing may be used to remove any zone of roughness which may be present in the surfaces of the disc resulting from the pressing step. In one embodiment, the pressure step may be applied before finishing the disc perimeters.
