Presented by the Aluminum Company of America (ALCOA), “Impact The Story of Metal in Motion” is a 1960s informational film detailing how aluminum is used to create parts and components for a variety of uses, primarily through extrusion and impact techniques. It was probably aimed at engineers and designers who were tasked with making parts of various kinds, to get their creative juices flowing. The narrator explains (starting at mark 01:45) that ALCOA makes many of its parts using extrusion, a moving punch, a stationary dye, and a slug of aluminum, with the film continuing on illustrating each process and type of impact, aided by animation. The film explains how different parts can be combined into a single impact (ark 03:50) thus eliminating the need for welding or joint assembly. “If you want larger impacts we have the know-how,” the ALCOA narrator boasts at mark 05:50. The film focuses on tolerances starting at mark 06:18, and the ALCOA “alumilite” process (mark 07:50) which is an electro-chemically applied coating that protects against wear. The film rolls on with the narrator praising the ALCOA impact process, its methodology, and its ease of use. At mark 10:48 the narrator further explains how such pieces can be used for electronics, and automation “reduces costs to a minimum.”
