The Application of Aluminum Alloys to Automobiles
As a typical light metal, aluminum alloys are widely used in foreign automobiles. The aluminum alloy components of foreign automobiles mainly include pistons, cylinder heads, clutch housings, oil pans, bumpers, heat exchangers, brackets, wheels, body panels and decorative parts.
At present, the United States, Japan, and Germany are the countries that use the most aluminum alloys in automobiles. For example, the amount of aluminum alloy used in the body reaches 80% for Volkswagen AudiA8 and A2 in Germany, and NXS in Japan. Aluminum alloys used in Shanghai Santana, FAW Audi and Jetta (all imported production lines) account for about 80 to 100kg. Some data show that replacing the traditional steel structure with an aluminum alloy structure can reduce the weight of the car by 30% to 40%, the engine 30%, and the wheel 50%. The use of aluminum alloys is one of the important ways to reduce the weight of automobiles, protect the environment, save energy, increase speeds and transport efficiency. Therefore, it is very necessary to research and develop aluminum alloy automobiles. Aluminum alloys have the main advantages of having light weights and good heat dissipation. With the development of engine technology, the valve structure has become the mainstream design trend of the engine.
At present, not only the piston, radiator, oil pan and cylinder block of car engine parts are made of aluminum alloys, but also the cylinder head and crankcase are made of this material. Using aluminum alloys to replace cast iron in engines has become a mainstream trend. The aluminum cylinder liner of French cars has reached 100%, and the aluminum cylinder block has reached 45%. In the next few years, with the successful development of high-strength and high-quality aluminum alloys and the continuous improvement of manufacturing processes, aluminum alloys will be used more and more to manufacture this type of part.
Aluminum alloys for automobiles can be divided into cast aluminum alloys and deformed aluminum alloys. Casting aluminum alloys are the most used in automobiles, accounting for more than 80%, including gravity casting, low-pressure casting and other special casting parts. Deformed aluminum alloys include plates, foils, extrusions and forgings. Although there are certain differences in the variety of industrial aluminum alloy materials used in various countries in the world, they are generally the same. Castings account for about 80%, forgings 1% to 3%, and the rest are processed materials. Deformed aluminum alloys account for a large proportion in the U.S. auto industry, reaching 36%.
