The Applications of Aluminum
Three main purposes
Nearly fifty years, aluminum has become one of the world's most widely used metal. In the construction industry, due to the appearance of aluminum in an excellent stability in the air and anodized while being widely used; in the aerospace and defense industry sector is also a large number of combination of aluminum alloy; on power delivery is commonly used high strength steel wire fill Strong aluminum cables; in addition, automobile manufacturing, container transport, daily necessities, household appliances, machinery and equipment, extensive use of aluminum and aluminum alloys.
Fourth, the aluminum market distribution and characteristics
Production of aluminum ingot is the raw material bauxite, the total amount of the world's bauxite resources of about 400-500 million tons, 10 million tons of reserves of countries of Guinea, Australia, Brazil, Jamaica and India, the aluminum in these countries bauxite accounted for 73% of the world's total reserves. The amount of aluminum produced mainly in the United States, the former Soviet Union, Canada, Australia, Brazil, Norway and other countries, production defiant a ball more than 60%. Sources of supply in addition to new aluminum, recycling aluminum also has a high proportion of aluminum recycling divided into recycling old material (the main source of beverage cans and car scrap), the new material recycling (processing of scrap) in two . Global primary aluminum production increased by nearly three years of about 1 million tons per year, production was 22.66 million tons in 1998, 1999 production was 23.6 million tons. The annual global consumption of aluminum increased radiation was only 100,000 tons; aluminum production growth relative terms is much lower. The United States is the world's largest aluminum producing and consuming countries, because of its limited domestic bauxite reserves, the annual need to import a lot of raw materials. China's output and consumption volume in third place.
