  The casting process properties of aluminum alloy are generally understood as the combination of those properties that are outstanding in the process of filling mold, crystallization and cooling
Cast aluminum alloy is an aluminum alloy suitable for refilling the mold in the molten state to obtain a casting blank with a certain shape and size
Cast aluminum alloy has the same alloy system as deformed aluminum alloy and the same strengthening mechanism as deformed aluminum alloy
Aluminum alloy is used in casting process because of its low density, high strength, good toughness and corrosion resistance
Aluminum alloy casting process is the main preparation method of traditional aluminum alloy, but it has been difficult to meet the needs of preparing high-performance aluminum alloy
Because: 1
The traditional process has been difficult to further improve the strength, plasticity, stiffness, heat resistance and corrosion resistance; 2
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; 3
As the alloy content increases, the plasticity often decreases, so the subsequent pressure processing cost increases and the yield decreases Therefore, the production cost has greatly increased the use threshold of advanced aluminum alloy, and the spray forming process has the dual advantages of performance and comprehensive cost, which can reduce the use threshold of advanced aluminum alloy, further improve the performance, and promote the spray forming process to obtain the scale cost advantage in a certain range
