The aluminum alloy fuel tank is a fuel tank made of aluminum alloy sheet. With the development of various new materials, the rust prevention problem of iron fuel tanks has become the biggest problem of fuel tank quality, especially in today's environmental protection work. Aluminum alloy fuel tanks are far superior to carbon steel and plastics in corrosion resistance, impact resistance, service life and recovery value.
The aluminum alloy fuel tank process is made in the same way as the basic iron layout, and the aluminum alloy fuel tank is not only able to meet the strength direction but also has a great advantage in corrosion resistance compared to iron and other new materials, and on the basis of the fuel tank. The organization has been further optimized to make its integrated structure more stable, simpler to manufacture and easy to produce. It has also become the first choice for large passenger cars and heavy trucks with high fuel consumption and high fuel quality requirements. Among them, the quality requirements of aluminum alloy welding and mold are the top priority of aluminum alloy fuel tank quality.
Aluminum alloy fuel tanks generally use 5 series alloys. The strength of the 5 series alloys is higher than that of 1 series and 3 series aluminum alloys. It is a medium and high strength alloy with high strength, high formability, high corrosion resistance, high surface treatment and good welding performance. Features. Therefore, it is widely used in automobile fuel tanks.
In 1980, the first aluminum fuel tank was produced in Europe. By 2004, there were more than 400,000 aluminum fuel tanks produced in Europe, and the maximum number of pillars reached 1,100 liters. The fuel tanks of trucks produced by Mercedes-Benz and MAN were 100. % is made of aluminum alloy. Its light weight is only 40% of the same volume steel fuel tank, no paint is needed, the production process is environmentally friendly, the service life is long, it can reach 10 years without corrosion, it is more than twice of the same structural steel fuel tank, and the material can be recycled. After the aluminum alloy fuel tank is scrapped, the recycling rate is above 85%.
In terms of heavy trucks: In the process of propulsion of domestic vehicles, the problem that affects the advancement of new models is the quality of China's oil. Among them, the quality of the fuel tanks that are the key to fuel is the key.
The aluminum alloy fuel tank not only meets the strength direction but also has a great advantage in corrosion resistance compared to iron and other new materials. It has also become the first choice for large passenger cars and heavy trucks with high fuel consumption and high fuel quality requirements. Aluminum alloy fuel tanks have occupied more than 80% of heavy trucks, passenger cars and multi-purpose vehicles, and are now occupying the fuel tank market in a booming development, and are also a leading direction in the development of fuel tank fittings.
