The preferred metal as an alternative to steel and iron is aluminum, which is only a third as dense as steel or iron, reduces the mass of the same steel structure in half when used in cars, and it never rusts. Do you know why aluminum alloy is suitable for cars? What is the future development trend of automobile aluminum alloy?
The application advantage of aluminum alloy in automobile
1. Improve fuel efficiency and load carrying capacity. The application of aluminum alloy in automobile can greatly reduce the body weight. With the same fuel, aluminum alloy automobile has a longer driving distance than ordinary steel body automobile, which improves the fuel efficiency. In addition, the reduction of weight is equal to the improvement of the vehicle's carrying capacity, which can increase the transport efficiency of the vehicle and reduce the transport cost.
2. Reduce working procedure and improve assembly efficiency. Aluminum alloy car overall structure, less welding spot, reduce the processing procedure, aluminum alloy overall body is about 35% lighter than steel welding body, and without rust treatment, only 25%~35% parts need spot welding, thus can greatly improve the assembly efficiency of the car.
3. Safe and comfortable. Aluminum alloy car is in the case of not reducing the car capacity to reduce the weight of the car, the body center of gravity is reduced, the car is more stable and comfortable. Because the aluminum alloy car is light, the mass is small, so the energy of collision is much smaller than the steel body car. In addition, due to the aluminum alloy material properties and body structure, can fully absorb the energy of the impact, so it is more safe.
4. High recovery and reuse rate of auto aluminum parts. Aluminum alloy melting point is low, easy to remelting recovery, the current recovery is not less than 90%.
5. The vehicle is light weight, energy-saving and consumption reduction, which is beneficial to environmental protection.
The development prospect of automobile aluminum alloy
About 86% of the more than 20,000 components of new-energy vehicles are made of metal materials. Taking TeslaModelS as an example, the net weight of a car is 2108 kg, which can be reduced by using light metals. Assuming that the automobile aluminization rate reaches more than 30%, it is expected that each new energy vehicle will use 630 kg of aluminum, and the amount of aluminum used by new energy vehicles will reach about 1.2 million tons in 2020. In the next five years, the total amount of aluminum used in automobiles will increase steadily, and it is expected to reach 5.21 million tons in 2020. The demand for aluminum used in automobiles will explode.
China's automotive aluminum will reach 5.2 million tons in 2020, from the high-speed, comfortable, beautiful, durable, lightweight, energy saving, environmental protection, reduce comprehensive cost and other comprehensive performance, aluminum alloy is undoubtedly the automotive industry modernization and lightweight materials, many countries are committed to the automotive aluminum alloy research.
As one of the pillar industries in China, the automobile industry will continue to develop at a high speed in the coming decades. The research and development of high performance aluminum alloy for automobile industry plays a decisive role in improving the international competitiveness of China's automobile industry, and at the same time, it will bring great economic and social benefits.
