The liquid metal is cast into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the method of obtaining the part or blank is called casting. The casting obtained by the casting method is called a casting.
Cast aluminum alloy has some advantages that other castings can't match, such as aesthetics, light weight and corrosion resistance, which makes it popular with users. Cast aluminum alloy castings have a wide range of applications in auto parts, various household items and industrial machine parts. Cast aluminum alloys have a lower density than cast iron and cast steel, but have a higher specific strength. Therefore, the use of aluminum alloy castings under the same load conditions can reduce the weight of the structure. Aluminum alloy has good surface gloss, corrosion resistance, thermal conductivity and casting properties.
