Aluminium castings have unparalleled advantages over other castings, including elegant appearance, lightweight quality and corrosion resistance, which makes it popular with customers, especially in the field of automotive new energy, aluminium castings have been widely used in the automotive industry.

Aluminium alloys have excellent casting properties. Due to its lower melting point (pure aluminium melting point is 660.23 Celsius, the casting temperature of aluminum alloy is generally730～750 Celsius), so various metal material models and casting methods such as pressure casting can be used to improve the quality, accuracy and surface finish of aluminum castings, and improve production efficiency. Due to the large heat of solidification and vaporization of aluminum alloy, under the same net weight standard, its solidification process is longer than that of cast steel and pig iron, and its fluidity is good, which is conducive to casting thick-walled and complex structure castings.

Compared with pig iron and cast steel, aluminum castings have a smaller relative density and higher specific strength. Therefore, the selection of aluminum castings under the same load standard can reduce the weight of the structure. Therefore, aluminum castings are widely used in the aerospace industry, power machinery and transportation machinery and equipment manufacturing. Aluminum alloy has good surface gloss and good corrosion resistance in air and water. Therefore, aluminum castings have a wide range of main uses in the production of civil containers. Pure aluminum has excellent corrosion resistance in amphoteric oxides, so aluminum castings also have some major uses in the chemical industry. Pure aluminum and aluminum alloy have excellent thermal conductivity, which is suitable for heat exchanger equipment used in chemical plant production and manufacturing, as well as parts that need good thermal conductivity, such as cylinder heads and piston rods of gas turbines. Aluminum castings are also suitable for manufacturing materials.
