The transformation of automobile industry will be the only way

On July 18th, Detroit filed for bankruptcy in the United States. It once jumped to the fifth largest city in the United States because of the rise of the automobile industry. Today, it has taken off the name of “automobile city” and its population has dropped from 2 million to 250,000, and it has gradually become an empty city.

According to relevant personage analysis, the single auto industry is the direct cause of bankruptcy in Detroit, especially with the continuous rise in oil prices, American cars with large displacements and high fuel consumption have met the challenge of Japanese cars with better fuel-efficient performance and broke out in 2008. The financial crisis gave Detroit a fatal blow. As the core manufacturing industry, the top three auto companies laid off 140,000 people.

Of course, the Detroit auto industry cannot represent the level of the global auto industry, but the bankruptcy of the city of Detroit has sounded alarm bells for many manufacturing cities, and it has also given the automotive industry a strong signal that it must transform. In fact, since the late 1980s, many automobile manufacturers in Europe, the United States, Japan, and so on have stepped up their research and development, and have increased their research and development efforts in new energy and new materials. For example, in cooperation with the Aluminum Corporation, the research on aluminum vehicles has been strengthened, and the proportion of aluminum alloys in the materials used for vehicles has been increasing year by year.

Looking at the domestic market, there is still a big gap between China-made automobile R&D and foreign countries. Since the 1990s, the domestic aluminum consumption and technical level have been lower than those of foreign automotive aluminum. The development and application of aluminum vehicles in Europe and the United States and other developed countries has been more than 30 years old, and the technology has matured to a trend of standardization and trainization. Although China is the largest producer and consumer of aluminum in the world, the proportion of aluminum used in the transportation sector accounts for only 18%.

Many automobile manufacturers have taken the road to transformation and upgrading in order to adapt to the competitive situation of the survival of the fittest. At present, in the field of logistics, lightweight automotive energy-saving, safety, and environmental protection meet the development requirements of the logistics industry and become one of the automotive R&D directions. The aluminum material itself is light in weight, and it is possible to reduce the weight of the automobile by building a car from aluminum. In the field of automobile manufacturing, aluminum alloy is the most widely used lightweight material. It is reported that about 12% of the world's current - 15% of aluminum consumption for the automotive industry, and some developed countries have even exceeded 25%.

Lightweight aluminum commercial vehicles, whose body is made of aluminum alloy profiles or plates, with high aluminizing rate, excellent structure, high strength, light weight, long service life, lighter weight compared to similar steel vehicles, saving more than 10% .

Surviving the fittest and taking advantage of the situation, the transformation of the automotive industry takes a long way to go, and the Detroit bankruptcy incident will become a long-term success for the automotive industry, always reminding the automotive industry of its mission of innovation and upgrading.
