The Property and Application of Aluminum Alloy Die Casting

Aluminum alloy die casting is popular chosen by a wide range of users because of many superiority which can not be compared with other casting process. Main advantages are good surface, light weight and corrosion resistance. With the development of lightweight automobile industry, aluminum alloy die casting is widely used in automotive industry.

Aluminum alloy die casting parts have smaller density but much higher intensity than any other castings. Under the same loading conditions, the application of aluminum alloy will reduce the weight of structure to a great extent. It explains why aluminum alloy die casting has a widespread use in the manufacturing of aviation industry, power machinery and transport machinery. Also due to its high surface gloss and corrosion - resistant quality in the atmosphere and freshwater, aluminum alloy die casting has found an increasingly wide utilization in the manufacturing of civilian utensils.

Due to the superior corrosion resistance of pure aluminum, no corrosion in nitric acid, acetic acid and other oxidizing acids, aluminum alloy die casting also has special application in chemical industry.

For the high heat conductivity of aluminum, aluminum alloy is suitable to make the spare parts for heat exchanging system and generating machinery, such like cylinder head of combustion engine and piston which requires high heat conductivity.

Aluminum alloy die casting parts have good casting properties. The melting point of pure aluminum is 660.230C, and the casting temperature for aluminum alloy is around 730-750C. Then aluminum alloy can be used in process of permanent mold casting and pressure die casting. The casted products will have better internal quality, much precise measurements, and higher surface gloss degree. Owing to the bigger latent heat of solidification and better release liquidity, the process and time of solidification for liquid aluminum is much longer than cast steel and cast iron under the same weight condition. The castings with thin wall and complex structure can be achieved by aluminum alloy die casting.

For so many advantages, aluminum alloy die casting has become the developing direction of the casting industry, and also aluminum alloy die casting parts have been popularly purchased by clients both at home and abroad. With the development of casting technology, aluminum alloy die casting will present its own special bearing in a bigger stage.
