What is the future of aluminum construction in rail transit construction?

Aluminum plays an important role in rail transit. Aluminum has the advantages of light weight, high strength, good corrosion resistance and so on, making its application in the field of rail transportation is very extensive. The average EMU is required to use aluminum alloy 9 tons, each subway, light rail, city fast track need to use aluminum alloy 6.5 tons, each trolley to use aluminum alloy 4.5 tons. It is expected that during the “13th Five-Year Plan” period, the construction of rail transit in China will require the use of high-end aluminum profiles of 504,000 tons. And with the field of rail transportation technology accumulation, body lightweight aluminum is in the future domestic aluminum market potential is huge.

Aluminum and aluminum sheet to become the main body of the vehicle body. Normally, about 3 tons of aluminum for each high-speed rail train is about 10 tons, of which about 8 tons of extruded profiles, and about 2 tons of other (sheet, foil, pipe, wire, forgings, etc.). According to statistics, it is estimated that 2014-2020, the domestic passenger line about 28,000 high-speed trains, about 11 tons of aluminum per vehicle, the need for aluminum about 31 million tons.

In terms of the number of projects or the scale of investment, urban rail transit is the most important. Compared with other modes of transportation, urban rail transit has the advantages of fast, high traffic volume, safe, punctuality and reliability, which solves the problem of urban traffic congestion and greatly facilitates people to travel, resulting in significant social benefits. The construction of the subway has stimulated the development of the national economy, in line with China’s large and medium cities to give priority to the development of public transport policy.

Urban rail transit mainly includes subway system, light rail system, monorail system, tram, maglev system, automatic guided orbit system, urban rapid track system. Among them, the most representative of the subway, the size of the urban rail transit industry accounted for more than 70%.

According to statistics, China’s declaration of subway construction of the urban population requirements or from more than 3 million people down to 1.5 million, which will make the conditions in line with the subway construction of the city from about 30 to about 90. It is estimated that by 2020, China will have at least 50 cities with subway, the potential planning mileage is huge.

Since 1863 the world’s first subway built in London and put into operation after the development of the history of rail transit changes, changing the power of a city. A railway from the history of the river came, tells us about the city once the glory and glory, but also to show people new hope and dreams.
