| Summary: | From staples to skyscrapers... from raw ore to high-tech alloys... from wafer-thin aluminum to massive spans of steel... metals give support, shape, and shine to the modern world. This program examines the uses of metal as a material in construction, car-making, and other practical applications. Focusing on aluminum, perhaps the most relevant metal in today's environmentally-conscious industries, the video looks at its origin, characteristics, ingredients, where aluminum is frequently found, and its many uses. Two case studies are also provided that outline the processes involved in making goods out of metal. Experts from the Alcoa corporation are interviewed. The high-pressure die casting process is also explored
