The casting process has far-reaching significance and influence on the development of 7075 aluminum alloy, the significance and function of casting aluminum alloy, and the casting process of aluminum alloy has far-reaching significance and influence on the development of 7075 aluminum alloy. If the aluminum alloy market is to be steadily improved, the casting process must be Continuous updating and improvement, the improvement of each step of the process has irreplaceable significance to the overall process. . 5 In addition to being used in daily life, with the continuous improvement of technology, aluminum alloys have also begun to be used in important transportation fields, such as aerospace structural materials, and are now expanding into the automotive field. The continuous development of aluminum alloy technology has become a general trend.

The casting process is the main preparation method of traditional aluminum alloys, but it is difficult to meet the needs of preparing high-performance aluminum alloys. First, it is difficult to further improve the strength, plasticity, stiffness, heat resistance and corrosion resistance of traditional processes; second, in the process of pursuing high performance, the cost of casting process rises rapidly due to the addition of equipment and the decline of yield; third , due to the increase in alloy content, the plasticity tends to decrease, so the cost of subsequent pressure processing increases and the yield decreases.

In the field of industrial materials. For a long time, the proportion of domestic building profiles has been high, while the proportion of foreign industrial profiles is higher. Industrial profiles are often technically difficult and have high added value. From the perspective of application fields, the construction industry is still the main field of aluminum profile application, far exceeding other fields, and the consumption is rising year by year, accounting for more than 63% of the total consumption as of 2009. In terms of different regions, the average consumption of aluminum profiles in the industrial field in North America, Europe and other developed regions in 2009 has exceeded 50%, while the consumption of aluminum profiles in China is only 32%. The consumption of aluminum profiles in the industrial field has great potential. It is estimated that the proportion of industrial aluminum profile consumption in 2015 will reach about 45~50%, and according to the relevant planning of the Chinese government, in the next 10 years, the proportion of industrial aluminum profiles in the total consumption of aluminum profiles will be close to 70%.

Therefore, the high cost of production has greatly raised the threshold for the use of advanced aluminum alloys, seriously affecting the development of the overall market size. In these aspects, the spray forming process has the dual advantages of performance and comprehensive cost, which can lower the threshold for the use of advanced aluminum alloys, and can further improve the performance. market, and in turn facilitates the spray forming process to gain cost advantages of scale. Therefore, the spray forming process will become the main production process of advanced aluminum alloys.
