Aluminum processing, using plastic processing methods to process aluminum ingots into materials, the main methods include rolling, extrusion, stretching and forging. Aluminum processing began to be produced in an industrial manner in the early 20th century. Before the 1930s, copper processing equipment was basically used, and the products were mainly used for aircraft manufacturing. After the 1960s, aluminum production developed rapidly, with an annual increase of about 4-8%. 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 larger aluminum processing plant and formed a production system. The products have been serialized, with seven alloy series, which can produce plates, strips, foils, tubes, bars, profiles, wires and forgings. (Free forgings, die forgings) eight types of products.

From the macro level of economic growth, the meso perspective of industry evolution, and the micro behavior of enterprise development, we have found that the current aluminum industry will become an inevitable trend from smelting primary electrolytic aluminum to deep processing. Aluminum processed products are generally priced by the "aluminum price + processing fee" approach. When the total downstream demand and structural increase are rapidly increasing, companies with technical advantages, channel advantages, cost advantages, and location advantages will not only have processing fees It can be guaranteed, and there is still the possibility of improvement. If the capacity expansion factor is added, the performance growth 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 companies above designated size in China. After the rapid development stage and fierce market competition, the basic pattern has taken shape. At present, my country's aluminum foil industry has a large number of production companies, and the industry concentration is low. No company has a significant market share, and no company can have a decisive influence 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. The average scale was small and there were many small companies. There was excessive competition in the field of low value-added products. .
With the rapid development of China's metal doors and windows, building curtain walls, transportation, 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, and new uses of aluminum Profiles will continue to appear, thereby promoting technological progress and the sustained and healthy development of the industry. The aluminum profile industry will continue to show a good development trend from 2011 to 2015.
With the rapid growth of China's aluminum profile industry, the sales revenue of the aluminum profile industry will also increase year by year. Statistics show that 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 domestic and international economic situation, 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 annual compound growth rate of sales revenue of China's aluminum profile industry from 2011 to 2015 is 20%. In 2015, China Aluminum The sales revenue of the profile industry will reach 1049.8 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, and it will reach 2.1 million tons in 2013. The compound annual growth rate of 2011-2013 will reach 17 %.
