New Application of Aluminum Alloy in the Car Industry

car industry

Expanding the application of aluminum in automobiles is one of the important ways to reduce the weight of automobiles in China. The comprehensive application and application of aluminum in the light-weighting of automobiles will reduce fuel consumption by 15 million tons per year and form 1.29 million tons of aluminum per year.

The number of large-scale all-aluminum passenger cars in the world has already occupied a large proportion. In recent years, it has been growing at a high speed. China is starting, it only accounts for a very low proportion of reserves. There is huge room for development. As of 2010, China’s large passenger car ownership was 1.16 million. If 20% of it is aluminized, it needs more than 350,000 tons of aluminum. The annual output of large and medium-sized passenger cars is about 120,000. If 30% of them are aluminized, they need 60-80,000 tons of aluminum per year.

In addition, miniaturization and lightweight can make China’s 200 million cars lose an average of 25% – 30%. Compared with the current level of fuel economy of 40 million tons, it should become the basic technical way to achieve the goal of energy-saving and emission reduction.

The present condition of China

At present, improving the lightweight level of medium-sized trucks in China, not only improving the quality utilization efficiency of heavy-duty trucks, but also adding objective economic and social benefits, and rationally allocating new benefits, can support the upgrading, replacement, and replacement of heavy-duty vehicles. The application of new lightweight materials can increase the user’s income and national taxation, and all of this comes from the improvement of transportation efficiency. From the essence, it will not need to invest in one side. It is a country, society, production enterprise, and user. A win-win situation. Fully in line with the needs of operating according to market rules, this is an opportunity that is difficult to meet in the lightweight of passenger cars and buses, and it is also a favorable condition for the lightweight of heavy-duty trucks.

The relevant government departments give active guidance and necessary encouragement policies to the production and sales of high-level and light-weight vehicles while strengthening overload and over-restricting governance.

Development of aluminum

In 1946, the earliest development of aluminum box trailers was developed. In the 1980s, all-aluminum trailers were developed. And in Europe & the United States, the transportation mode of tractor-trailers accounted for more than 80% of the road traffic, while less than half of them were in Europe and the United States. There is still a big gap between the two countries. The aluminum semi-trailer technology in developed countries such as Europe and America, especially in North America, is quite mature. At present, the penetration rate of aluminum semi-trailers has reached more than 70% and has reached professionalization and standardization.

Most of the trailers in China are made of steel vehicles. The body is self-contained, with high fuel consumption and large exhaust emissions. Manufacturers are mixed, the industry has low thresholds, and illegal assembly is prevalent. China’s logistics and transportation industry have not yet achieved specialization, standardization, scale, and overload, which requires further management and regulation.

Aluminum semi-trailer in China

At present, China’s all-aluminum semi-trailer has made major breakthroughs in its development, and has successfully developed a representative all-aluminum semi-trailer and has begun to enter the market. Gradually adapt to market demand.

Although the relevant enterprises have achieved major breakthroughs in the research and development and industrialization of all-aluminum trailers, they have the conditions for large-scale production and have carried out more successful promotion work. However, due to various factors, promotion and application are more difficult. First, the production cost is higher. Second, the transportation behavior needs to be further improved. Third, the standard system needs to be improved.

Industrial policy

Regarding the industrial policies for the promotion and application of light green trailers in China, it is recommended that the state should increase the regulation of transportation regulation on the basis of the original favorable policies, further introduce relevant encouragement and stimulus measures, and promote the comprehensive promotion and application of all-aluminum trailers. The realization of the goal will have a greater promotion.

At present, countries around the world are making great use of aluminum alloy materials to manufacture rail vehicles. The number of aluminum alloy bodies that China has put into use should reach 120,000, and this speed of development is accelerating with the rapid spread of high-speed rail applications. The number of aluminum alloy car bodies has reached more than 10,000, far exceeding the total demand of the world. This demand has greatly stimulated the demand for aluminum alloy materials in China and the development of aluminum alloy deep processing industry. It has promoted the prosperity and development of a large number of related industries.

Advantages of deep processing of aluminum alloy

Deep processing of aluminum alloy profiles can minimize waste loss and maximize economic benefits. In the upstream industry, aluminum bending is easier to achieve, and it can also achieve overall tempering of large parts, improve strength, deep processing of aluminum alloy materials, and wide application. With aerospace, shipbuilding, military, radiators, laptop casings, high-voltage switches, curtain walls, power generation, warehousing logistics, and other fields.

Aluminum alloy deep processing has advantages in the production of aluminum alloy materials, and the downstream machinery processing industry is at a disadvantage in terms of cost efficiency and quality. The deep processing of aluminum alloy materials is an inevitable trend. Relevant enterprises should pay attention to this change. Aluminum is widely used in the transportation sector because of its lightweight. It not only saves energy and reduces emissions, but its light characteristics are also the key to the development of the aerospace industry. Another important sustainability feature of aluminum is its ability to cycle. This is also an important part of the research on the life cycle GHG emission reduction evaluation of aluminum products.
