Aluminum Die Casting: Advantages & Applications

Evaluating the appropriate manufacturing process you can utilize to design an aluminum component is very importance. Many common yet popular processes are available for aluminum forming, but one of the most common ones that most designers consider is aluminum die casting.

In the realm of automotive, industrial, and telecommunications products, aluminum die casting is a favored technique employed by experts. This method is also frequently utilized in the creation of electrical, hydraulic, lighting, and furniture components.

In essence, a metal-forming process of designing intricate aluminum components is known as aluminum die casting. This involves heating aluminum alloy ingots to extremely high temperatures until they become completely molten. Subsequently, under high pressure, a liquid aluminum called a mold is inserted into the hole of the steel die. Because the die is made up of two halves, the solidified molten aluminum gets separated and displays the cast aluminum part. The product typically exhibits a soft texture and requires minimal or no machining. The method can be repeated multiple times, utilizing the ultimate mold until it deteriorates, making aluminum die casting pertinent for the enormous production of aluminum parts.

The utilization of aluminum in casting offers a significant advantage, which is the capability to define the essential properties. Despite the project and specific application, there is always an appropriate aluminum alloy die casting solution available. Hence for a better decision, it is crucial to pick the appropriate alloy based on the required characteristics.

Please find below a list of the essential properties and characteristics to choose the type of alloy for an application.

  • Corrosion Resistance – only changes when alloyed but perfect in its natural state
  • Strength – estimated by temper, tensile strength, and yield
  • Heat Treating: reduce chemical segregation and improve workability
  • Formability – the ability to experience plastic deformation
  • Weldability – solidification shrinkage, thermal conductivity, oxide coating, hydrogen solubility
  • Machining – bendability, able to be drilled, resistant to low temperatures
