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. Therefore, aluminum alloy castings are widely used in the aviation industry and the manufacture of power machinery and transportation machinery.
Aluminum alloy has good surface gloss and good corrosion resistance in the atmosphere and fresh water, so it has a wide range of uses 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 and are used in chemical production.
