Aluminum alloy die castings have some advantages that other castings cannot match, such as beautiful appearance, light weight, corrosion resistance and other advantages, which make them widely favored by users, especially since the lightweight of automobiles, aluminum alloy castings have been widely used in the automobile industry. Applications.

The density of aluminum alloy die castings is lower than that of 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. Therefore, aluminum alloy castings are widely used in the aviation industry, power machinery and transportation machinery manufacturing. 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, heat exchange devices used in chemical production, and parts that require good thermal conductivity in power machinery, such as cylinder heads and pistons of internal combustion engines, are also suitable for aluminum alloys. Manufacturing of die castings.

Aluminum alloy die castings have good casting properties. Due to the low melting point (the melting point of pure aluminum is 660.230C, and the pouring temperature of aluminum alloy is generally about 730-750oC), casting methods such as metal mold and pressure casting can be widely used to improve the inherent quality, dimensional accuracy and surface of the casting. finish and productivity. Due to the large latent heat of solidification of aluminum alloy, under the same weight conditions, the solidification process of aluminum liquid lasts much longer than that of cast steel and cast iron, and the fluidity is good, which is conducive to casting thin-walled and complex castings.

Alloy aluminum casting has many advantages, making it one of the most popular casting products in the development direction of the foundry industry and purchasing customers. In the future, with the progress of aluminum alloy casting technology, it will show its style on a larger stage. .
