Precautions and common problems of aluminum alloy gravity casting

1. What are the application areas of aluminum alloy gravity casting? What are its main advantages?
The main application of aluminum alloy gravity casting is in the fields of automobiles, motorcycles, motors, communications, and hardware tools. Therefore, its applications are still very extensive. In this casting method, its main advantages are low melting point and good casting performance, and it can also avoid secondary processing due to problems such as porosity, thereby increasing costs.

2. What should we pay attention to for aluminum alloy gravity casting?
We should pay special attention to the gravity casting of aluminum alloy. The main ones are:
For castings, if it needs to be engraved, then whether the engraving depth meets the requirements. For the painted face, whether the spray thickness meets the specified requirements. And whether the casting process is carried out in accordance with the regulations and specifications, and whether the sequence of the processes is correct, etc. In addition, the inside of the groove can be cleaned frequently.

For the above mentioned, I hope everyone can take it seriously and grasp it, so as to smoothly carry out aluminum alloy gravity casting and obtain satisfactory casting results.

3. What is the temperature range of aluminum alloy sand gravity casting? And AC4B aluminum alloy material, is it die-casting or gravity-casting?
The temperature range of aluminum alloy sand gravity casting in aluminum alloy gravity casting is specifically 620℃-680℃. However, the exact value should be determined according to the type of material, the structure of the casting and the quality of the casting. AC4B aluminum alloy material is a relatively special die-cast aluminum alloy material in the JIS H 5202-1999 standard. However, it can be used for gravity casting, and this is often done.
