Cast aluminum alloy has some advantages that other castings cannot match, such as beautiful appearance, light weight, corrosion resistance and other advantages, making it widely favored by users, especially since the lightweight of automobiles, cast aluminum alloy castings have been widely used in the automotive industry Applications.

  The density of cast aluminum alloy is lower than that of cast iron and cast steel, but its specific strength is higher. Therefore, the use of aluminum alloy castings under the same load conditions can reduce the weight of the structure, so aluminum alloy castings are widely used in the aviation industry, power machinery and transportation machinery manufacturing. Aluminum alloy has good surface gloss and good corrosion resistance in the atmosphere and fresh water, so it is widely used in the manufacture of civil utensils.

Pure aluminum has good corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings also have certain uses in the chemical industry. Pure aluminum and aluminum alloys have good thermal conductivity. They are also suitable for heat exchange devices used in chemical production and parts that require good thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines. manufacture.
