Caption: Hot "breakdown" reversing mill in the Oswego, New York, plant which will become part of the new Alcan Aluminum Corporation, U. S. fabricating subsidiary of Aluminium Limited (Alcan). Aluminum sheet is being reduced from 18-inch rolling ingot to one-inch thickness.
Caption: Coiling of Properzi rod at end of production line in new aluminum rod mill built by Nesca Aluminum Ltd., subsidiary of Reynolds Extrusion Company Ltd. at Riviere, La Malbaie, Quebec. Plant has a capacity of 50,000,000 lbs. per year of 3/8 inch redraw rod. Rod will be converted to cable for Quebec's Manicougan hydroelectric project.
Caption: Coils of aluminum sheet from the hot line are heat treated in furnaces and then brought to the four-high mill for rolling to thickness desired by customers at Alcoa's Tennessee Works.
Caption: One of two aluminum strip mills recently supplied to the Aluminio Earle, Amorebieta plant in the vicinity of Bilbao, Spain by Nouvelle Spidem of Paris. This is the first cold breakdown mill used in conjunction with an existing two high reversing hot mill. It is designed for a maxium starting thickness of 7 mm. and a minimum finished thickness of 1 mm. The mill stand is equipped with hydromechanical screwdown and is completed with a coil conditioning station and 2 coilers; the coiler No. 2 is used for coiling foil stock on a spool.
Caption: Work on the world's deepest diving submarine is rapidly nearing completion. The Aluminaut, first all-aluminum research submarine, which is being built for Reynolds International, Inc., is scheduled for launching this summer. Aluminum 1/8 to 3/16 inches thick, was fabricated in sections.
Caption: Scalping aluminum billets prior to rolling at Aluminum Company of America plant.
Caption: In the slitter operation at Alcoa, Tennessee, Works of Aluminum Company of America, coiled sheet is slit into narrow widths to order.
Caption: Milling architectural aluminum panel produced by a new casting process at Alcoa's Cleveland Works.
Caption: Operator prepares to charge light aluminum plate into a "skin pass mill" from new charging table installed at Olin Mathieson Chemical Corporation's aluminum plant to facilitate material handling of heavier gauge products. The skin pass mill reduces the thickness of plate and sheet, controls their flatness and imparts the surface finish required for their end uses. The plant near Hannibal, Ohio, has just completed a two-year, multi-million-dollar expansion program.
Caption: Many of America's new ordinance tanks are powered by husky engines assembled from these 585-pound aluminum engine blocks, shown here being prepared for shipment from the sand foundry at Alcoa's Cleveland (Ohio) Works. The big castings, termed diesel crankcases by the trade, are five feet long, and eventually will develop 750 horsepower.
Caption: Die cast aluminum "crocodile snouts," coming down the production line at Alcoa's Chicago works. Some of the largest die castings ever produced, they are oil pans for 220-horsepower Cummins diesel engines. Although their weight (33 pounds) is not a record, the sheer length, width and breadth of the parts is considered extraordinary. The dimensions are four feet by 14 inches by 12 inches. Alcoa utilizes a machine with locking pressures of 2,000 tons. The steel dies weigh over 25 tons. The casting replaces a 55-pound aluminum permanent mold piece. If the same part were cast iron, says Cummins, it would weigh over 120 pounds.
Caption: High speed aluminum nail making machine features quality control of wire stock.
Caption: Spinning aluminum cable at Kaiser Aluminum's new plant at San Leandro, California. The plant has just gone into operation after being converted in record time from its former use as a GM auto assembly plant.
Caption: Cryogenic testing of aluminum at minus 452 degrees F, was conducted in specially equipped mechanical testing machine shown here being operated by engineer Earl Swetnam at the Batelle Memorial Institute. Research, sponsored by The Aluminum Association, produced conclusive findings that aluminum not only retains but actually improves upon its desirable strength characteristics at extreme low temperature of liquid helium.
Caption: Positioning rear section of Saturn fuel container in special weld fixture preparatory to welding in the manifold sump. Sump has four ports where fuel or liquid oxygen can be loaded or unloaded. Fabrication is by Chance Vought Astronautics Division of Ling-Temco-Vought, Inc.
Caption: Pouring aluminum from new electrically-controlled Ajax Melting Furnace at Arwood Corporation's Cleveland plant. Unit is capable of melting up to 1,500 pounds at a time. To the left of this unit are two 100-pound units which are capable of melting down a full charge of metal in 15 minutes.

Caption: Welding spacers into titanium coils requires ingenuity in applying gas protection. Note hose, right center, which supplies argon through the coil; additional argon is supplied by a special diffuser, visible to the left of the welding gun. The welding gun is the prime source of the argon. (Photo courtesy of Titanium Metals Corporation of America.)
