Caption: An aluminum slab, 1/4 in. thick and 150 ft. long, enters the 110-inch hot reversing mill at the Ravenswood, West Virginia, plant of Kaiser Aluminum & Chemical Corporation.
Caption: Aluminum plate gets a smooth surface in a milling machine at Alcoa's Davenport (Iowa) Works. The surface cutter already has finished the right side of the plate with a characteristic milling pattern. The left side is unmilled. Capable of handling plate up to 10 feet wide and 40 feet long, the mill shapes, routs, contours and surfaces metal.
Caption: Heavy gauge aluminum moves into a horizontal heat treating furnace at the Davenport, Iowa Works of Alcoa. The furnace accommodates metal in widths up at 150 inches and lengths of 100 feet in gauges from .250 to six inches.
Caption: An operator observes aluminum sheet moving through one of the five stands in the new Reynold's Metals Company cold rolling mill at Sheffield, Alabama. Gages above his head indicate roller pressure, temperature and other information.
Caption: A mill operator controls the initial rolling operation at Alcoa's new aluminum foil plant at Lebanon, Pennsylvania.
Caption: First metal is tapped from a new 40,000-ton-per-year aluminum potline at Reynolds Metals Company's Longview, Washington, reduction plant. The first of three 168 new potlines scheduled for the plant under Reynolds' $325 million expansion and modernization program began in 1966, the new potline has started production several months ahead of schedule.
Caption: Aluminum ingot cast from a reverbatory furnace utilizing the Oxy-Fuel process at Alcan's Oswego Plant.
Caption: Blaw Knox tandem mill at new Goose Pond Island Plant of Revere Copper & Brass, Inc. continues reduction of an 18 or 24 inch ingot to thickness of a fraction of an inch. The aluminum is being blocked into a coil after which it will be further processed into finished coils or cut into individual sheets up to 20 feet long.
Caption: Symbolic of the new concept of "Metaullics" - the pumping of molten metal like water is this picture taken by Metal Pumping Services Division of Carborundum Co.
Caption: Unusually wide and long (over lO5'), the Boeing 747 wing skins rarely test the performance of this massive stretcher. Located at Alcoa's Davenport (Iowa) Works, this machine was installed with the future in mind since industry demands points to even longer and wider aluminum plate than the current giant 747 requires. Stretching provides flatness and aligns internal structural stresses. The alumium plate is placed between the huge jaws and lengthened as the machine slowly exerts its a-million pound pull.
Caption: Worker at Davenport, Iowa, works of Alcoa removes a scalped ingot from the bed of a horizontal scalping machine which produces a milled finish from a rough cast ingot. Ingot is then ready for rolling into plate, sheet and foil. (Photo courtesy Aluminum Company of America.)

Caption: Quality inspection of 12,000 lb. rolling ingot at Ravenswood, West Virginia works of Kaiser Aluminum and Chemical Corporation.
