The theme of “innovation dare to play to do excellent and stronger” 2017 China Top 500 Enterprise Summit Forum September 9 to 10 held in Nanchang City, Jiangxi Province. In which the lightweight material industry development forum, experts and scholars on the magnesium, titanium, aluminum and other non-ferrous metals on the importance of lightweight material industry development and prospects for its prospects. In this paper, some of the views to be excerpted to readers.
Ding Wenjiang: magnesium is a green material, has a lot of application value

Forum, the Chinese Academy of Engineering Ding Wenjiang to “green magnesium, rare earth cultivation” as the title delivered a speech.
Why is magnesium green? Ding Wenjiang said, “green” there are two indicators, one is to extract a ton of new metal and recycling a ton of metal energy consumption ratio of the lower the more green, “recycling a ton of magnesium with refining a ton of magnesium energy ratio is probably About 5%, if the aluminum recovery is about 7% to 9%, steel 20% from this point of view, from the recovery of energy ratio, the magnesium is green.
Second, look at the material is not sustainable use. Ding Wenjiang said, “steel, iron consumption rate by the world, there are 70 years there is no, aluminum and 220 years, only magnesium is almost inexhaustible.”
The so-called “rare earth cultivation”, Ding Wenjiang said, magnesium in life with less. Because magnesium has some shortcomings, such as strength, deformation capacity, corrosion resistance of the disadvantages. How to break through such a bottleneck? Ding Wenjiang said, you can use rare earth to improve.
Ding Wenjiang said, “I do magnesium for 32 years, very ashamed to now magnesium has not really go to the world, in our country did not really get large – scale industrial applications, but in any case, 32 years there are some progress.
What is the specific progress? Ding Wenjiang introduction, the first is a series of research progress on magnesium, the second is a series of technological breakthroughs, the third is in some key important parts of the application has expanded, the fourth is the development of magnesium A series of functional materials.
Ding Wenjiang that in recent years, the United States, Japan fine plastic materials research efforts in the weakening, are to engage in nano-materials, biological materials. And when the manufacturing industry back, they have no talent. China should seize this opportunity, in the manufacturing power from the manufacturing power to the time when the metal’s function will be more and more strong.
Cao Chunxiao: titanium alloy in the aviation industry will usher in a broad prospect
Academician of the Chinese Academy of Sciences Cao Chunxiao to “Titanium and Aero Engine of the indissoluble bound” as the title delivered a speech.
Last year in January, the State Council formally approved the formation of China Aero Engine Group program, and in August formally established. Aero engines and gas turbines National science and technology major projects have also officially launched this year. Aero engine is a high-tech crystallization, very difficult, but also China’s comprehensive national strength of the performance, is an important symbol of innovation-oriented countries.
“A generation of material technology, a generation of aviation equipment, is a true portrayal of the history of the world’s aviation.” Cao Chunxiao said, and titanium alloy which is an important member of the aviation material family, and the engine plays an important role in aviation equipment. Titanium in the last century 50′s advent, greatly promoted the development of aero-engine. The demand for aero-engine has contributed significantly to the development of titanium. Between the two is a dialectical relationship, interdependence, mutual promotion, the achievements of the titanium and aero engine between the good fortune.
“Looking to the future, titanium alloy this dark horse hair and can not be received, and continue to expand its sphere of influence, a black in the end.” Cao Chunxiao said, titanium aluminum alloy will usher in a very broad prospects. US NASA predicts that titanium aluminum compounds in the aviation launch of the application by 2020 can reach 20%. And China’s titanium aluminum metal bond compounds have made great progress. Institute of Metal Research Institute of Chinese Academy of Sciences developed a titanium alloy low pressure turbine blade precision casting.

Liu Xiangmin: the next 20 years is the development of aluminum material development of 20 years
China Aluminum Group, a member of the group, Professor Liu Xiangmin, a senior engineer at the time of his speech, the last decade is China’s lightweight materials development and research and development of a good period. China Aluminum Corporation invested about 20 billion yuan of research and development costs to achieve the upgrading of materials. “At present our research mainly to the third generation of aluminum-based and fourth generation, we completely eliminated the first generation and second generation.”
Liu Xiangmin said that China Aluminum Corporation in order to make the material technology has been very good development, the establishment of professional management of professional system, the nine aluminum processing enterprises formed the aluminum processing division, “the past few years the annual output increased by 15% , China Aluminum Company to more than 80% extension rate, operating conditions are very healthy. ”
Liu Xiangmin said the Wright brothers after the invention of the aircraft, the aircraft did not get a lot of applications. Until the emergence of aluminum has progress, aviation has become an increasingly important part of transport.
When talking about the car lightweight business, Liu Xiangmin said that the aluminum company in this area is a combination of production and research. “In the production and construction process, the vehicle lightweight manufacturing of materials is not a major obstacle, the application of engineering is our focus on the direction of our various parts of the car, the various parts of the structure of the formation of a series of products, material performance has also been the industry Widely praised, including some parts that seem simple but complex. ”
Liu Xiangmin said, “the weight of the car or to promote the weight of materials must be multi-disciplinary, multiple industries, a number of professional cross-border combination of the results of a business to promote lightweight or very difficult and we are willing to work together with everyone this work.”

Liu Xiangmin that “the next 20 years, should be 20 years of aluminum, aluminum materials to develop 20 years in the world gave us a very good opportunity and window.”
Xu Jinxiang: Organization of lightweight innovation center in the form of industry chain
China Nonferrous Metals Industry Association Magnesium Branch president Xu Jinxiang said that China’s magnesium aluminum development has come to a very critical moment. Although the overall level of the world’s advanced there is a certain gap, but by contrast, magnesium is China’s development of new metals for decades, belonging to the late metal, the prospects are wide.
When it comes to the lightweight innovation center, he stressed that “if you really want our country from a magnesium power into a power, no comprehensive strength, no cooperation, no cross-sectoral work, is not complete.” “Hope With the innovative center platform, with the concept of innovation and working mechanism, we can make our national magnesium industry from big to strong.
How can the league really play a role? Xu Jinxiang that must be organized in accordance with the form of the industry chain may have vitality. “The platform must have a terminal or machine manufacturing enterprises to participate in. This alliance is a viable. Must have a lead. Lead is not necessarily the most important, but it must start from the chain of the industry, from The market began, starting from the application.Therefore, from the magnesium industry point of view, there is no terminal business, there is no machine manufacturing industry to participate in the platform want to have vitality, creative, dynamic survival is very difficult. Innovation platform in the mechanism of the system, in operation can find such a complete set of Chinese characteristics of the approach.
