Castings made of aluminum alloys are widely used in various industries. Especially since the lightweight of automobiles, aluminum alloys are favored by the automobile industry due to the advantages of light weight and corrosion resistance.

1. Cover aluminum casting: light weight and corrosion resistance

Aluminum alloy has good surface gloss and good corrosion resistance in the atmosphere and fresh water. Pure aluminum has good corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings are widely used in the automotive industry.

2. Cover aluminum casting: excellent thermal conductivity

The density of cast aluminum alloy is lower than that of cast iron and cast steel, and the strength is relatively high. Therefore, the use of aluminum alloy castings under the same load conditions can reduce the weight of the structure. The cylinder head in an automobile is a special aluminum casting product. The purpose of using aluminum casting is that it can withstand large thermal shocks, and the characteristics of aluminum castings are relatively good thermal conductivity. For the cylinder head, it can improve its performance. Thermal efficiency to avoid overheating of components.
