Aluminum processing, processing aluminum ingots into materials by plastic processing methods, the main methods are rolling, extrusion, stretching and forging. Aluminum processing began to be industrially produced in the early 20th century. Before the 1930s, copper processing equipment was basically used, and the products were mainly used in aircraft manufacturing.
After the 1960s, aluminum production has developed rapidly, with an annual growth rate of about 4 to 8%. The products are widely used in aviation, construction, transportation, electrical, chemical, packaging and daily necessities industries. The output is second only to steel, ranking second in metal materials. In the mid-1950s, China built a large aluminum processing plant, forming a production system. The products have been serialized. There are seven alloy series, which can produce plates, strips, foils, pipes, bars, profiles, wires and forgings. (Free forgings, die forgings) eight categories of products.
From the macro level of economic growth, the mesoscopic perspective of industry evolution, and the microscopic behavior of enterprise development, we all find that the current aluminum industry will become an inevitable trend from the smelting of primary electrolytic aluminum to intensive processing. Aluminum processing products are generally priced in the way of "aluminum price + processing fee". When the total downstream demand and structural increments increase rapidly, companies with technological advantages, channel advantages, cost advantages, and location advantages will not only have processing rates. It can be guaranteed, and there is still the possibility of improvement. If the factor of capacity expansion is superimposed, the growth of performance will be rapid and significant. In recent years, China's aluminum profile industry has grown rapidly and has fully developed into a highly competitive industry. As of the end of 2010, there were 824 aluminum profile enterprises above designated size in China. After a period of rapid development and fierce market competition, the basic pattern has taken shape. At present, there are many production enterprises in my country's aluminum foil industry, and the industry concentration is low. No one company occupies a significant market share, and no one company can have a decisive impact on the development of the entire industry. In 2010, the national aluminum foil output was about 2 million tons, and there were more than 250 companies engaged in aluminum foil production, with an average output of about 8,000 tons.
With the rapid development of China's metal doors and windows, building curtain walls, transportation industry, chemical industry, power equipment industry, national defense and military industries, the demand for aluminum profiles will continue to grow. At the same time, new products, new processes, new uses of aluminum Profiles will continue to appear, thereby promoting technological progress and the sustainable and healthy development of the industry. From 2011 to 2015, the aluminum profile industry will still show a good development trend. With the rapid growth of China's aluminum profile industry, the sales revenue of the aluminum profile industry will also increase year by year. According to statistics, from 2005 to 2010, the compound annual growth rate of sales revenue of China's aluminum profile industry was 35.20%. According to the current economic situation at home and abroad, combined with the sales revenue data of China's aluminum profile industry from 2005 to 2010 and China's economic growth data, it is roughly estimated that the compound annual growth rate of sales revenue of China's aluminum profile industry from 2011 to 2015 is 20%. The sales revenue of the profile industry will reach 1,049.8 billion yuan. With the rapid development of the downstream industry of aluminum foil, its demand for aluminum foil will continue to increase. By 2012, the consumption of aluminum foil will reach 1.8 million tons, in 2013 will reach 2.1 million tons, and the compound annual growth rate from 2011 to 2013 will reach 17 %.
