Aluminum

Description

Aluminum is extracted and purified from clays and rocks at a British plant by purifying bauxite ore to aluminum oxide and reducing this oxide to molten metal. The influence of economic factors is seen in the location of aluminum plants, which consume large amounts of electrical energy. In the United States, plants are located close to the power source rather than to ore deposits; in England, where electricity is uniformly priced throughout the country, location is determined by proximity to the raw material. Various desirable properties of the product aluminum and its alloys are shown, as well as the link between specific properties of each alloy and its end use.
