Cast aluminum alloys have a lower density than cast iron and cast steel, while the specific strength is higher. Therefore, the use of aluminum alloy castings under the same load conditions can reduce the weight of the structure, so in the aviation industry and power machinery and transport machinery manufacturing, aluminum alloy castings have been widely used.

Aluminum alloy has a good surface gloss, good corrosion resistance in the atmosphere and fresh water, so it has a wide range of uses in the manufacture of civilian utensils. Pure aluminum has good corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, and thus aluminum castings have a certain use in the chemical industry. Pure aluminum and aluminum alloys have good thermal conductivity, heat exchange devices used in chemical production, and parts that require good thermal conductivity on power machinery, such as cylinder heads and pistons for internal combustion engines, are also suitable for use with aluminum alloys manufacture.
