### ALUMINUM 1 (Data in thousand metric tons of metal, unless otherwise noted) Domestic Production and Use :In 2002, 11 companies operated 16 primary aluminum reduction plants; 6 smelters were temporarily idled. The 11 smelters east of the Mississippi River accounted for 75% of the production; whereas the remaining 11 smelters, which included the 9 Pacific Northwest smelters, accounted for only 25%. Based upon published market prices, the value of primary metal production was $3.9 billion in 2002. Aluminum consumption was centered in the East Central United States. Transportation accounted for an estimated 34% of domestic consumption in 2002; packaging, 25%; building, 17%; consumer durables, 7%; electrical, 7%; and other, 10%.

### ALUMINUM Events, Trends, and Issues :The 121,000-ton-per-year Troutdale, OR, smelter and a 76,000-ton-per-year potline at the Rockdale, TX, smelter were permanently closed. Most of the smelter capacity that was idled in the Pacific Northwest at the end of 2001 remained off line. However, as energy shortages began to ease and take-or-pay energy contracts took effect, some smelters in the region began limited restarts. Imports for consumption increased, reversing a 2-year decline. Canada and Russia accounted for approximatelythree-fourths of the total imports. U.S. exports decreased slightly. Canada and Mexico received an estimated twothirds of total U.S. exports. The price of primary aluminum ingot fluctuated through August 2002. In January, the average monthly U.S. market price for primary ingot quoted by Platts Metals Week was 64.65 cents per pound; in August, the price was 62.55 cents per pound. Prices on the London Metal Exchange (LME) followed the trend of U.S. market prices. The monthly average LME cash price for August was 58.59 cents per pound. According to American Metal Market, prices in the aluminum scrap and secondary aluminum alloy markets increased during the first quarter of the year before beginning a general downward trend that continued through the end of September.World production continued to increase as temporarily idled capacity and new capacity expansions were brought onstream. Inventories of metal held by producers, as reported by the International Aluminium Institute, decreased slightly during the first half of 2002. Inventories of metal held by the LME, however, exceeded 1.2 million tons, reaching levels not seen since the first half of 1995.

World Resources :Domestic aluminum requirements cannot be met by domestic bauxite resources. Potential domestic nonbauxitic aluminum resources are abundant and could meet domestic aluminum demand. However, no processes for using these resources have been proven economically competitive with those now used for bauxite. The world reserve base for bauxite is sufficient to meet world demand for metal well into the 21st century. Substitutes : Copper can replace aluminum in electrical applications; magnesium, titanium, and steel can substitute for aluminum in structural and ground transportation uses. Composites, wood, and steel can substitute for aluminum in construction. Glass, plastics, paper, and steel can substitute for aluminum in packaging.
