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 advanced aluminum alloy can be greatly improved threshold, serious influence the development of the overall market size.In these areas, the injection forming technology has the dual advantages of performance and comprehensive cost, can reduce the use of advanced aluminum alloy bar, still can further improve performance, in a certain range to achieve to generation of steel, aluminum and cultivate advanced aluminum alloy market rapidly, and, in turn, promote the scale of spray forming technology for the cost advantage.Therefore, the injection forming technology will become the main advanced aluminum alloy production process.
