China Should Strengthen the Research and Development of Automotive Body Aluminum

China should strengthen the research and development of aluminum for automobile bodies. In 2003, China’s total automobile production exceeded 4 million, becoming the world’s fifth-largest automotive industrial country in one fell swoop. Therefore, the research and development of automotive body aluminum will bring enormous economic and social benefits. At present, the auto aluminum ratio in China is still relatively low. Generally, the amount of aluminum used for bicycles for cars is about 40-50 kilograms, and the average aluminum ratio is 4%, which is far lower than that of developed countries. In recent years, developed countries have introduced aluminum body concept cars or mass-produced models. The Audi A8 sedan, which was first mass-produced by Audi in 1995, is a representative example of successful use of aluminum materials in the manufacture of automotive bodies. In addition, the development of domestic automotive aluminum products is not balanced, and the development of aluminum hubs is overheated. Auto body panels are basically blank. China's auto body aluminum is still in the stage of development, introduction, absorption, and digestion. Researchers believe that in order for China’s auto industry to quickly catch up with the developed countries’ level of development, there is an urgent need to develop aluminum in automotive bodies in the following areas: Work: (1) Research has been conducted to improve the pressure formability of aluminum by crystal refinement and alignment; (2) To develop alloys that improve the welding performance of aluminum and steel; (3) To establish an aluminum alloy standard for automobile bodies. More adaptable aluminum alloys for automotive bodywork, in particular to put the main force on 6xxx alloys; (4) Establish recycling systems for end-of-life vehicles and develop recycling technologies for end-of-life vehicle materials; (5) Develop new aluminum for automotive bodywork Alloys, such as aluminum foam, superplastic aluminum alloy and so on. Contemporary automobiles are moving in the direction of lightweight, high speed, safety, comfort, energy saving and low pollution. Since the automobile body occupies 30% of the total weight of the automobile, developing aluminum alloys for high-performance bodywork and recycling technology of scrapped automotive materials has become an imperative issue. The scientific research and investment in this area will surely bring about a huge economy. Benefits and social benefits. Source: Chinalco Information Network
