With the development of engine technology, the valve structure becomes the mainstream design trend of the engine. Compared with a two-valve engine, the cylinder head of four-valve per cylinder generates more heat than the cylinder head of two-valve per cylinder. The all-aluminum alloy cylinder head is the best solution. At present, not only the piston, radiator, and sump block are made of aluminum alloy, but also the cylinder head and crankcase are also used.
Nowadays, it has become a mainstream trend to use aluminum alloy instead of cast iron in engines. In the coming years, aluminum alloy materials will be increasingly used to manufacture such components with the success of high-strength high-quality aluminum alloy materials and the continuous improvement of manufacturing processes. Aluminum alloys for automotive use can be divided into cast aluminum alloys and deformed aluminum alloys. Aluminum alloys are the most used in automobiles, accounting for more than 80%. They are divided into gravity casting, low-pressure casting, and other special casting parts. Deformed aluminum alloys include sheet, foil, extrusion, forging, etc. Although the composition of aluminum alloy materials for industrial use varies from country to country, it is generally the same. Its variety composition: castings accounted for about 80%, forges accounted for 1%, and the rest were processed materials. Deformed aluminum alloys account for 36% of the automotive industry in the United States.
6000 series aluminum alloy is the most used aluminum alloy in the automotive industry. It has excellent forming performance, high strength, corrosion resistance, folding, high surface performance, etc.
Substituting aluminum alloy plates for steel plates inside and outside the car can reduce the body by 40% C, thereby reducing the net quality of the vehicle by about 10%. Ford Model T, Ford Prodigy, FORD pickup truck, Jaguar XJ, Ferrari 360, Chrysler Prowler, Volkswagen 31 Lupo, Audi A2, A8, Honda Hybrid a (the Honda Insight), Honda NSX, Teste-Model, S, etc. The use of ABS to manufacture engine covers and trunk covers is even more numerous.
6061 aluminum alloy is widely used in ABS, but the heat treatment process is complicated. There should be good forming performance before stamping so that the strength can be increased quickly during the stamping process to high concave resistance. Therefore, pre-timed treatment T4P must be performed between solid solubility treatment and paint treatment to obtain good performance. After soluble T4P paint treatment, the 6061 aluminum alloy plate can take into account the two requirements, but the process parameters have a great influence on the final performance. Insoluble treatment does not sufficiently reduce the precipitation power of artificial aging during T4P and lacquer process. Long insulation time may lead to grains' coarseness. Low pre-aging humidity reduces the stability of plate placement and the hardening effect during the lacquer process. The too high temperature will affect the forming performance of the stamping process. It can be seen that the solid solubility and T4P process parameters should be optimized to obtain the ideal comprehensive performance.
