The market for aluminum profiles for transportation in China has been growing rapidly. The application of aluminum profiles for automobiles, high-speed trains, urban light rail, aerospace, ships, containers, and bicycles has continued to grow, and it has occupied 1/3 of the aluminum profile market in China. In recent days, the development of aluminum profiles for automobiles has become even more noticeable.
For many years, the automotive industry has been conducting experimental research on the structural design, material selection, and manufacturing technologies of automobiles, striving to develop safe, reliable, high-speed, comfortable, energy-saving and environment-friendly modern automobiles. The primary issue is the lightweighting of automobiles. Lightweight car is a better way to achieve high speed, safety, environmental protection and comfort.
Aluminum alloy instead of the traditional steel manufacturing car, can reduce the quality of the vehicle by 30%-40%, the engine can be reduced by 30%, the cylinder and the cylinder cover can be reduced by 30%-40%, the car aluminum body than the original Steel products are lighter than 40%, and aluminum alloy wheels can reduce weight by up to 50%.
The demand for lightweight vehicles makes the development of aluminum alloys face a broader space. According to experts' predictions, the aluminization rate of automotive materials reaches over 60%, which is economically desirable. Based on this, it is speculated that the limit of aluminization of automobiles in the future can reach 30% to 50% or more.
The new automotive aluminum development and application focus on three aspects. First, the development and application of the aluminum alloy body and aluminum frame and aluminum alloy profile. Second, the full aluminumization of the anti-shock and door rigid structure. Third, turn all parts of the aluminum aluminized.
There is a certain gap between domestic automobile materials and foreign countries, especially in cars. The composition of the materials used in the products or technologies in the early 1990s was basically the same as that of the same model in the same period in foreign countries, but the amount of aluminum materials was lower than the current foreign types of automobiles. Due to the limitation of aluminum price and component processing technology, some aluminum alloy parts of the imported models have been replaced with other materials, which restricts the application of aluminum alloy materials in domestic automobiles.
With the acceleration of the world’s auto lightening process, especially after the accession to the WTO, the international competition in the auto market is becoming increasingly fierce. Domestic autos have to reach the level of similar foreign cars. The increase in automotive aluminum is an inevitable trend, and the amount of aluminum alloys will vary with various types. The increase in automobile production will surely provide China's aluminum industry with a vast market and new development opportunities.
