    　　In recent years, the Chinese market and strong demand for industrial aluminum, aluminum products a lightweight, corrosion-resistant, easy to shape, recyclable characteristics emphasized in China under the premise of energy saving and environmental protection, industrial aluminum in transportation, appliances, electronics and machinerythe significant increase in equipment and other fields of application alternative to traditional metallic materials such as steel, copper, aluminum gradually become a trend.
　　
　　Today, almost all international car brands have increased the development and application of aluminum alloy. Automotive industry "energy-saving effect of aluminum instead of steel" how much? Research data, to reduce the weight of the means of transport is an effective way to reduce fuel consumption, the key auto parts with high strength steel can only reduce a 10% of the weight; using aluminum to reduce 40% of the vehicle weight. Energy saving in addition to the low-carbon, aluminum also has the strong performance of the collision, the collision energy absorption is twice that of steel sheet.
　　
　　The leapfrog development process of China Railway, lightweight is the main way to achieve high-speed heavy. Mainly by rail transport of bulk raw materials in China, the main channel of railway coal car with unlimited potential, the aluminum alloy sheet since back Shanxi Province, Hebei Province, Datong-Qinhuangdao line, for example, is China's west-east coal to the coastal industrial areas one in the running on aluminum coal train, compared with the all-steel train having the same vehicle weight, approximate structure, not only the body weight decrease five tons, vehicle load increase five tons objectives can also be achieved.
　　
　　In addition, the structure of the electrical equipment upgrades, promotion of wind turbine blades waving to aluminum products; machinery and equipment in the field of agricultural machinery, construction machinery, mining machinery, instrumentation, extensive use of aluminum. With the national industrial policy, industrial restructuring as well as consumer requirements on product quality improvement, large mainland industrial aluminum market opportunities, Chung Mong "domestic and overseas, supplemented by" marketing strategy, lock the transportation, machinery and power engineering three aluminum products demand in core areas, in order to meet the new round of growth of the aluminum.
