As a typical lightweight metal, aluminum alloy is widely used in foreign automobiles. Foreign automobile aluminum alloy components mainly include pistons, cylinder heads, clutch shells, oil pans, bumpers, heat exchangers, brackets, wheels, body panels and decorations. Parts etc. At present, the United States, Japan, and Germany are the countries that use the most aluminum alloys for automobiles. For example, the Audi A8 and A2 of Volkswagen in Germany and the NXS of Japan use 80% of aluminum alloys for the body.

Some data show that replacing traditional steel structures with aluminum alloy structures can reduce car mass by 30% to 40%, manufacturing engines by 30%, and wheels by 50%. The use of aluminum alloys is one of the important ways for automobiles to be lightweight, environmentally friendly, energy-saving, speed-up and efficient in transportation.

Therefore, research and development of aluminum alloy cars is now very necessary. The main advantages of aluminum alloy are light weight and good heat dissipation. With the development of engine technology, valve structure has become the mainstream design trend of engines. Compared with a two-valve engine, a cylinder head with four valves per cylinder generates more heat than a cylinder head with two valves per cylinder. Using an all-aluminum alloy cylinder head is the best solution. At present, not only the piston, radiator, and oil pan and cylinder block of car engine parts are made of aluminum alloy, but also the cylinder head and crankcase are also made of this material.

Under the current situation, it has become a mainstream trend to use aluminum alloy instead of cast iron in engines. The aluminum cylinder liner of French cars has reached 100%, and the aluminum cylinder body has reached 45%. In the next few years, with the successful development of high-strength and high-quality aluminum alloy materials and the continuous improvement of manufacturing processes, aluminum alloy materials will be more and more used to manufacture this type of parts. https://www.aluminum-price.com/

Aluminum alloys for automobiles can be divided into cast aluminum alloys and deformed aluminum alloys. Cast aluminum alloys are the most used in automobiles, accounting for more than 80%, which are divided into gravity castings, low-pressure castings and other special casting parts.

Deformed aluminum alloys include plates, foils, extruded materials, forgings, etc. Although there are certain differences in the variety and composition of industrial aluminum alloy materials in various countries in the world, they are generally the same. Its variety composition: castings account for about 80%, forgings account for 1% to 3%, and the rest are processed materials. Wrought aluminum alloy accounts for a large proportion of the US automobile industry, reaching 36%.
