Aluminum Die Casting Alloys

Die casting is the process that involves forcing molten metal into a mould cavity using high pressure. Choosing the best aluminum alloy for die casting is an essential task. Aluminum alloys constitute various macro and microelements, such as titanium, iron, silicon, copper, magnesium, manganese, tin, zinc, and nickel. In addition, each aluminum alloy has different mechanical and physical properties. Die casting alloys aluminum are gaining more popularity due to their ability to withstand high temperatures. In addition, most aluminum castings are lightweight.

Types of Aluminum Alloys For Die Casting

  1. A360 Aluminum Alloy

This type of aluminum alloy is characterized by fluidity and great pressure tightness. Some of the benefits of A360 aluminum alloy include better ductility, corrosion resistance, and great strength, especially at high temperatures. In addition, the A360 aluminum alloy is hard to cast.

  1. A380 Aluminum Alloy

This is the most commonly used aluminum alloy in the die casting process. Most individuals consider this type of alloy because it’s Budget-friendly. In addition, A380 doesn’t require elevated levels of pressure tightness or corrosion resistance. Various benefits of A380 aluminum alloy: lightweight, corrosion resistance, high thermal conductivity, extremely strong, especially at high temperatures, high electrical conductivity, and retains dimensional stability, even if the shapes are complex.

  1. ZA-12

This type of aluminum alloy is characterized by lower density, high melting point, and medium aluminum content.

  1. A383 Aluminum Alloy

This type of aluminum alloy is used when you require specific die-filling properties. In addition, you can consider A383 aluminum alloy if you’re forming intricate components. Below are some of the key benefits of A383 aluminum alloy include the lower probability of cracking and offers high strength, especially at elevated temperatures.

Things to Consider When Selecting the Best Aluminum Alloy for Die Casting

  1. Physical properties
  2. Composition
  3. Chemical composition
  4. Mechanical properties

Aluminium Die Casting Alloys Application

  1. Can be used in handheld devices due to properties such as durability, lightweight, rigidity, and RFI/EMI shielding.
  2. Enhances the efficiency of automotive fuel due to its lightweight properties.

3. Ideal for housing and electronic connectors because aluminum alloys are having excellent shielding performance and electrical properties, even in higher temperature environments.

4. Aluminum alloys are ideal for infrastructure and networking equipment, especially in the computing industry.

Conclusion

In addition, there is a minimal functional difference between recycled(secondary) and pure/extracted(primary) aluminum. Secondary or recycled aluminum comprises melted aluminum mixed with other elements, such as copper, iron, and magnesium. Producing secondary aluminum is more economical compared to pure aluminum. Most people shy from using pure aluminum due to its high cost of extraction. Above is concrete information about die casting alloys aluminium.
