1. Aluminum alloy aluminum plate for high-speed rail
The components of China Railway Passenger Dedicated Line are CRHI, CRH2, CRH3 and CRH5. Except for the CRHI type, the other three types of EMUs are made of aluminum alloy. At the end of 2009, the number of domestic EMUs reached 287, and 417 columns will be added in 2010. In 2012, the EMU is expected to reach 1,000 columns, and 200 columns will be added in 2011-2012. In 2009-2012, 800 trains of EMUs will be required, totaling 9,360, of which aluminum brakes are estimated to reach 7,800. Each engine uses 8-9 tons of aluminum profiles and 1.5 tons of aluminum sheets. It is roughly estimated that China's EMUs from 2009 to 2012 will require 70,000 tons of aluminum profiles and 12,000 tons of aluminum sheets.
2. Alloy aluminum plate strip for automotive
The application of aluminum in automobiles is the earliest and successful application of the global automotive industry. It is also the industry with the largest amount of aluminum in the transportation industry. The aluminum sheet is mainly used for car body and heat exchanger systems and vans. Car compartments, luxury bus skins and floors, light car bodies, heavy-duty fuel tanks and air reservoirs, trunk lids, engine covers, sedan and bus doors. In 2009, the amount of aluminum strip used in the manufacture of passenger cars, luggage compartment doors and body was about 30,000 tons, and the heat exchanger system used aluminum sheets with foil of about 100,000 tons.
3. Aluminum plate for large ship
Aluminum is mainly used for high-speed boats on boats: hydrofoil, flying, speedboats, cruise ships, hovercrafts, sailboats, catamarans, sea patrol boats, passenger and passenger ferries. The application areas of aluminum include ship side, bottom plating, keel, ribs, ribs, partitions, engine pedestals, decks, roof and side panels of sea-going vessels, and chimneys. Aluminum boats have developed rapidly in foreign countries, such as Europe, America, Japan, and Australia. In recent years, aluminum boats manufactured in China have also increased, but most of them are exported.
4. Aluminum alloy sheet for aircraftThe ARJ21-700 aircraft mainly uses 7050 and 7150 aluminum alloy sheets and aluminum extrusion materials, mainly used for the upper wing panels, beams, fuselage purlins, fuselage frames, bulkheads, and wing rafters of large aircraft. Wing ribs and spars and seat rail components.
In addition to aviation, rail transit vehicles, automobiles and boats, the transportation equipment manufacturing industry's corresponding transportation facilities are also a market for aluminum applications that cannot be ignored. In addition, the amount of aluminum used in electric bicycles, mountain racing cars, and containers is also considerable. Mr. Chen Jinya, President of Alcoa Asia Pacific, once said: "In the next ten years, 50% of the development opportunities of the aluminum industry are in China. China represents more than 50% of the world's development opportunities, including aviation, automobiles, buses, yachts and other fields."
