Aluminum alloy has low density, high strength, good toughness and corrosion resistance and other advantages, is widely used as structural materials in the aerospace industry, at the same time, also are actively developing as auto advanced materials and applied to high-grade car engine.Then the casting process of aluminum alloy is what kind of that, let's take a look at.Casting is a traditional aluminum alloy main preparation methods, but has been difficult to meet the needs of the preparation of high performance aluminum alloy.First, the traditional process is difficult to further improve the strength, plasticity, rigidity, heat resistance and corrosion resistance;Second, in the process of the pursuit of high-performance, casting cost due to add equipment and yield decline rapidly rising;Third, due to the increasing content of alloy, plastic is often reduced, and the subsequent pressure processing costs, yield reduction.As a result, the casting production of the high cost of the use of
