Caption: Pouring 700-lb. ingots in the Port Henry Works of Alcoa of Australia Pty. Ltd., near Geelong, Victoria.
Caption: Archer Products, Inc., aluminum foil operation at Winston Salem, North Carolina. All rolling mills are equipped with automatic X-ray gauge control of web dimensions.
Caption: Two Sunbeam aluminum coil annealing furnaces at Dow Chemical Company Madison Division. Each furnace is designed to operate between 300°F. and 1000°F. and is capable of annealing up to 100,000 pounds of aluminum coil per load. Cooling takes place inside the furnace. A continuous roller chain practically eliminates maintenance and lubrication costs as its carries the furnace cars in and out of the furnace without the use of conventional wheels or bearings.

Caption: This 60-inch, five-stand, Blaw Knox cold rolling finishing mill can operate at mile-a-minute speeds. Sheet previously hot rolled to a thickness of one-eighth inch is precision rolled by this equipment to .008 to .016 inch in thickness. Photo shows the entry end of the mill, one of two computer-controlled cold mills at Alcoa's Warrick Operations, near Evansville, Indiana. This unit produces finished sheet 48 inches wide. The other turns out 36-inch wide close tolerance, high quality sheet for volume use.
Caption: New casting equipment designed to provide sheet ingot has gone into operation at the Longview, Washington, plant of Reynolds Metals Co. This includes a 90,000-lb. holding furnace and enlarged cast house and the vertical casting unit pictured. The new unit casts unalloyed ingot, extrusion billet and sheet ingot. The sheet ingot goes direct to Reynolds sheet plants eliminating need to recast unalloyed ingot at the plant.
Caption: Aluminum slab, 1, 1/4 inches thick, 150 feet long, entering 110 inch hot reversing mill at Kaiser Ravenswood works.
Caption: Explosively forming aluminum at Martin Company, Denver, Colorado, in joint research with University of Denver.
Caption: Hot continuous sheet mill at Alcan's Oswego, New York, plant reduces aluminum sheet to 1/8 inch reroll stock.
Caption: The 72-inch continuous hot mill at the fabricating plant of Alcoa of Australia Proprietary Limited, Point Henry, Victoria. This mill, the only one of its kind in Australia, can roll aluminum to unusually thin gauges. It produces high quality re-roll stock for finish rolling in cold-milling facilities.

Caption: Hot titanium billet is placed in 50,000-lb. steam drop hammer at Arcturus Manufacturing Corp. plant in Oxnard, California. The 50,000-lb. hammer is largest operating in the West. Equipment is used to forge titanium into hemispheres and other components for aerospace vehicles. Steam to operate the hammers is produced in natural gas-fired generator that has a capacity of 100,000-lb./hr. (Photo courtesy Southern Counties Gas Co.)
Caption: Aluminized plastic wrapped between layers of Alcoa aluminum tube aids operation of the world's largest cryogenic heat exchangers. Designed and fabricated by Air Products and Chemicals, Inc., 30 such units now are helping to produce helium at three new plants in the mid-West. Aluminum is employed in the "kingsized" heat exchangers because of its light weight, and ability to retain strength and resist becoming brittle at minus 320°F and lower. Selected over traditionally used copper and stainless steel, aluminum reduced this giant's weight by one hundred tons.
