Aluminum alloy die-casting has the advantages that some other castings can't match. The aluminum alloy die-casting parts have the advantages of beautiful appearance, light weight and corrosion resistance. Aluminum alloy die-casting parts are widely favored by users. Especially since the automobile is lightweight, cast aluminum alloy castings have been widely used in the automotive industry. Since the density of cast aluminum alloy is smaller than that of cast iron and cast steel, 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 aluminum alloy castings are widely used in the aviation industry and power machinery and transportation machinery manufacturing.
Aluminum alloy has a good surface gloss and good corrosion resistance in the atmosphere and fresh water, so it has a wide range of applications in the manufacture of civilian utensils. Pure aluminum has good corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings have certain applications in the chemical industry. Pure aluminum and aluminum alloys have good thermal conductivity, heat exchange devices used in chemical production, and parts requiring good thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines, etc. manufacture.
