In recent years, most of the newly-built metro trains in China are aluminum alloy car bodies. Compared with the traditional steel car bodies, aluminum alloy car bodies have incomparable advantages compared with other materials - lighter weight, which means that the energy consumption of rail transit can be reduced to a greater extent, which is in line with the social advocacy of green, environmental protection and sustainable development in China. Based on this, aluminum alloy car body is gradually becoming the choice of urban subway, light rail, high-speed rail and other rail transit upgrading.

In the field of rail transit development, Zhongwang group spared no effort in R & D and innovation. According to the reporter of aluminum plus network, the group has successfully completed the production of aluminum extrusion products for maglev project recently. The product has reached the standard of "weight reduction" of aluminum alloy profiles for maglev train version 2.0. Among them, Zhongwang group has more strict control on the linear density of profile, and constantly improves the technical process To provide high-quality aluminum alloy profile deep-processing products for the maglev train version 2.0, and help China's transportation sector achieve faster and better development.

It can be seen that aluminum alloy profiles are of great practical significance for rail transit weight reduction, speed-up, noise reduction and energy consumption reduction. In addition to Zhongwang group, many aluminum profile enterprises have been innovating and changing in the field of public transport lightweight in recent years. Looking at China, for example, Chinalco Sapa helped Chongqing rail transit, jungle aluminum helped China's high-speed rail "going out", and Luoyang Midas rail car aluminum profiles The project will continue to help the whole aluminum processing industry chain to move towards the high-end field, and walk out of a path of innovation, green and sustainable development.

Green waters and green mountains are golden mountains and silver mountains. This is the development concept that China has been advocating and is also the direction of unremitting efforts of aluminum processing enterprises. We firmly believe that the development of lightweight rail transit will have a broader prospect.
