Caption: Artist's rendition of the National Aerospace Plane (NASP) in flight. The colors shown reflect the actual temperatures to be encountered by this vehicle. Titanium based materials will account for a large proportion of the airframe and engine.
Caption: Hoisted aloft by a crane operator at Warrick Operations, this 14-ton aluminum ingot will be rolled into thin sheet. Produced in an electromagnetic caster (EMC) which uses a powerful magnetic field to confine the molten metal until it cools, this new technology provides a smoother ingot surface which requires little or no scalping.

Caption: The new AX-S hard aluminum spacesuit developed by NASA Ames researcher, Hubert E. "Vic" Vykukal.
Caption: Euramax's new 2500 metric ton extrusion press in The Netherlands. This plant is considered one of Europe's most sophisticated. Computer software integrates and controls every step of the extrusion process, from billet preparation to profile out-transport.
Caption: Withdrawing rolling ingot from the electromagnetic casting installation in the South Ingot plant of Alcoa's Tennessee operations.
Caption: Accumulator at Alcoa's Tennessee operations stores 4 minutes of sheet with mill running at 5000 fpm.
Caption: Euramax Coated Products' new 63 inch paint line in The Netherlands. Seen from the coil-payoff end it can handle aluminum, galvalume, or steel substrates.
Caption: National Aluminum's computerized paint line at Anniston, Alabama. The paint line is capable of painting vertical extrusions up to 30 feet in length. (Picture courtesy of Edward J. Klein, National Intergroup Inc., Pittsburg, Pennsylvania.)
Caption: Sheet ingots are cast by direct chill at Commonwealth Aluminum, Lewisport. Kentucky. Having a capacity of 90,000 lbs. per cast, the casters employ a tilt-type mold carriage and an internally guided singleacting hydraulic main cylinder of 21" bore. Each casting machine is powered by a 50 hp hydraulic drive. The casting stations were built by Loma Machine, a Hill Acme Company.
Caption: An operator checks a monitor displaying thickness of aluminum strip on a light-gauge slitting line at the new Logan Aluminum plant at Russellville, Kentucky. Accuracy of strip thickness is held to within ±0.1 percent with the use of AccuRay 7000 Micro measuring system.
Caption: This 50,000-ton forging press at Wyman-Gordon Company's Worcester, Massachusetts, plant produces large airframe components from aluminum and titanium. Put in operation in 1955, it is one of the largest in the world and was a part of the Air Force's heavy press program. It was purchased by Wyman-Gordon in 1982. See story on filtration of ingot poured for the press.

Caption: An aluminum-lithium ingot emerges from the mold in the new Loma-Mann semi-continuous casting plant at the Kitts Green Works of Alcan Plate Limited, West Midlands, U.K. The equipment employs PLC control of all functions, integrated to liquid metal supply, allowing the casting operation to be undertaken with operating personnel divorced from the casting environment. Wellman Furnaces Ltd. of West Midlands undertook complete design, in conjunction with Alcan engineers, including programming of the control functions linked to the Alcan patented pulsed water feed system. The plant can cast up to 25 metric tons at once with an ingot length of 5500mm (18 feet). Casting speed is 300mm (11.8 inches) per minute with an accuracy of +/- 0.5%. Controls automatically start and stop the machine.
Caption: The role of Reynolds Metals Company's technology in transportation applications is demonstrated in its production of aluminum plate used in the space program.
