1. Aluminum alloy gravity casting, will it have a good effect on the production and manufacture of aluminum alloy wheels?

In the production and manufacture of aluminum alloy wheels, if aluminum alloy gravity casting is used, then it depends on the specific situation, because it can also use low pressure casting and forging. In general, low pressure casting is relatively common, and forging, its mechanical properties are better than low pressure casting. Therefore, we should choose the right one according to different situations and requirements.


2. In the gravity casting of aluminum alloy, is there a difference in the composition of the aluminum alloy, and will it have different properties?

In the gravity casting of aluminum alloy, the composition of the aluminum alloy, if it is different, will be different in the performance of the aluminum alloy, because if the silicon content is high, then the aluminum alloy will have Good flow properties, and its copper content is too high, then, the flow properties of aluminum alloy is relatively poor. Therefore, which aluminum alloy should be used specifically should consider its performance requirements to prevent problems during the casting process.


3. In the aluminum alloy gravity casting, can you not use the sand core?

Whether the sand core can be used in aluminum alloy gravity casting, the main thing is to look at the specific casting method. If it is for gravity casting and low pressure casting, then the sand core is used, while in high pressure casting, No sand core is required. In addition, if the casting structure is relatively simple, it is possible to use no sand core. Therefore, according to the above descriptions, it is impossible to answer this question.
