Why are aluminum castings widely used in certain fields?

This is because the cast aluminum alloy used in aluminum castings has some excellent properties. For example, if compared with cast iron and cast steel, it has lower density and higher strength, which can effectively reduce weight. Therefore, it is widely used in aviation, as well as in power and transportation machinery.

2. What is the future development trend of aluminum castings?

The future development trend of aluminum castings is currently very promising. Because it has many advantages that other materials or products do not have, and its development in the casting industry is also very good, loved and welcomed by customers. So based on the above explanations, the above conclusion has been drawn, and in this question, the answer is that the development trend is good. 

3. How to solve the problem of a large number of pores in aluminum castings?

In simple terms, aluminum castings refer to aluminum or aluminum alloy parts obtained by using sand molds or metal molds and using liquid aluminum or aluminum alloys. If a large number of pores appear, a mold can be used to repair the cold welding machine for repair and resolution, thereby eliminating this defect problem. 

For aluminum castings, through the above questions and the specific answers they provide, I believe that as long as everyone takes them seriously and masters them in a timely manner, they can gain some benefits, and also realize the application of knowledge, as well as the reasonable and flexible application in practical work, in order to improve the effectiveness of product use.
