Application of aluminum alloy

In order to reduce the self-weight of the car, first of all, on the basis of improving the strength and reliability of the material, the limited element analysis method is used to optimize the design of the car structure, and the parts are rational, thin, hollow and miniaturized. The second is to use lightweight materials. So far, the work mentioned in the previous paragraph has been basically completed, and there is no great potential to dig. Therefore, the use of lightweight materials has become the development trend of the global automotive industry, mainly to increase the proportion of plastic, light alloy, high-strength steel and composite materials. Whether it is the improvement and mining of traditional car materials, or the development of new materials, the main purpose is to reduce fuel consumption, purify tail gas, extend the life of the car, and improve the performance of the car. Since the mid-1970s, the main industrialized countries have seen the broad application prospects of light alloy in mechanical manufacturing, especially in automotive manufacturing. From the perspective of energy conservation and emission reduction, Europe and Japan make a large number of light metal parts. At present, light alloys are the most used in cars except steel.
Among various light alloy materials, aluminum has become the first choice of lightweight in the world with its advantages. And aluminum resources are rich and easy to recycle, which is very conducive to environmental protection. Therefore, it can reduce self-weight, improve the rigidity of the body, increase driving speed and load, improve performance, and improve efficiency. The aluminum instead of steel, with aluminum copper is the development trend, will gradually become the leading material of the vehicle. Use aluminum instead of steel in the car can reduce the weight of the parts. Usually, using a 1 kg aluminum alloy can reduce the car by 2.25 kg.
There are more and more examples of aluminum as light-quality structural materials. At present, the average of 70 kg of aluminum per car, accounting for about 6%of the mass of the car. According to the latest estimates, the amount of aluminum use in recent years will reach 120 kg. In the past two years, the American-made cars have strong competitiveness in the world, which is directly related to the increase in the use of aluminum parts. According to a survey report from the California International Automobile Structure Institute, by 2000, the aluminum consumption of automobiles will reach 6 million tons.
