Aluminum alloy casting, as an important metal processing method, is widely used in many industrial fields. It involves melting the aluminum alloy and injecting it into a pre-designed mold. After it cools and solidifies, the aluminum alloy casting of the desired shape can be obtained. This process not only has a long history, but also occupies an important position today because of its unique advantages and applicability.
The casting method of aluminum alloy must be selected according to its unique physical and chemical properties to ensure the best casting effect. Due to the differences in the components of aluminum alloys, their properties and crystallization processes will also be different. Therefore, a reasonable selection of casting process is crucial to prevent or reduce casting defects and thus optimize the quality of castings.
Aluminum alloy casting process performance
The casting process performance of aluminum alloys is mainly reflected in its fluidity, shrinkage, air tightness, casting stress and air absorption. These characteristics are not only affected by the alloy composition, but also closely related to various factors in the casting process, such as the heating temperature of the alloy, the complexity of the mold, the design of the pouring and riser system, and the selection of the pouring shape.
