The American Society of Mechanical Engineers designated the 50,000-ton Alcoa and Wyman-Gordon presses as Historic Mechanical Engineering Landmarks. The Alcoa press weighs 8,000 tons and is 87 feet (27 meters) tall. The die table is 26 by 12 feet (7.9 by 3.7 meters), and the maximum stroke is 6 feet (1.8 meters). [13]
