What is the casting technology of aluminum alloy
Aluminum alloy has the advantages of low density, high strength, good toughness and corrosion resistance. It is widely used in aerospace industry as structural materials, and is also actively developing as advanced materials for automobiless and used in high-grade car engines.
Casting technology is the main method of traditional aluminum alloy preparation, but it is difficult to meet the needs of high performance aluminum alloy. First, it is difficult for traditional technology to further improve strength, plasticity, rigidity, heat resistance and corrosion resistance; second, in the process of pursuing high performance, the casting process cost increases rapidly due to the increase of equipment and finished product rate; thirdly, due to the increase of alloy content, plasticity tends to decrease, so the subsequent pressure processing cost increases and the yield of finished products decreases.
Therefore, the high cost of production greatly improves the threshold of advanced aluminum alloy and seriously affects the development of the overall market scale. In these aspects, spray forming technology has the double advantages of performance and comprehensive cost, which can reduce the threshold of use of advanced aluminum alloy, further improve the performance, realize the replacement of steel with aluminum in a certain range, so as to cultivate the market of advanced aluminum alloy quickly, and to promote the jet forming process to obtain the scale cost advantage. Therefore, spray forming technology will become the main production process of advanced aluminum alloy.
