The main alloying element of 7075 aluminum plate is zinc, which has high strength and good mechanical properties and anodic reaction. It is mainly used in the manufacture of aircraft structural structures, mold processing, mechanical equipment, etc., which require high strength and corrosion resistance.
Based on the above advantages and uses, the 7075 aluminum plate has also been widely used in the market in China. According to statistics from relevant experts, in 2011, the production capacity of the original aluminum plate has reached six times that of 2001. In the ten years between, the annual growth rate of 7075 aluminum sheet production has reached 20%. The government's support, technological breakthroughs, and demand pull are all reasons for the soaring output of electrolytic aluminum alloy aluminum coils.
Under the current circumstances, China's aluminum alloy aluminum coil capacity accounted for more than 40% of the world's share of production capacity and consumption. Just a comparison with developed countries, there is still a big gap. According to relevant data, in the domestic market in 2011, the aluminum alloy aluminum coil has a performance consumption of 21 million tons, and the per capita consumption is 15 kilograms, while in the United States it is 30 kilograms, and in Japan it is higher, and the per capita consumption is close. 35 kg. Therefore, only in terms of quantity, the domestic demand for aluminum plate growth is very large.
The current situation is that China's domestic aluminum alloy aluminum coil industry has entered a surplus period. For the aluminum industry, which is now a highly competitive micro-profit era, then the adjustment and upgrading of the industrial structure is inevitable. In order to break through this pattern, the aluminum sheet alloy aluminum coil industry must start from two aspects: controlling production capacity and expanding downstream markets.
Now the primary task of the electrolytic aluminum alloy aluminum coil industry is to effectively control the pace of capacity expansion. During the “Twelfth Five-Year Plan” period, the planned construction of the proposed projects in China has reached 15 million tons per year. If these projects can be put into production as scheduled, then by 2015, the domestic production capacity of 7075 aluminum sheets will reach 10.6 million tons/year. The scale will far exceed market demand.
