Aluminum is one of the most popular choices as a die casted metal. Manufacturers can cost-effectively produce intricate parts with a shorter lead time. Here we have briefly discussed the characteristics, advantages, types, and applications of aluminum die-casting metals.

Aluminum Alloy Characteristics

Aluminum metal alloys have some unique characteristics that distinguish them from other die casting alloys. Some key characteristics of aluminum alloy are:

  • Very lightweight
  • Great corrosion resistance
  • Superior electrical and thermal conductivity
  • Can withstand high operating temperatures
  • Excellent strength-to-weight ratio with good stiffness
  • Great EMI/RFI shielding properties
  • Wide range of surface finishing options

Advantages of Aluminum Die Casting

Aluminum die casting offers multitudes of benefits over other metalworking techniques. Some of the main advantages of aluminum die casting are as follows:

  • High production efficiency
  • Produce parts with Intricate details
  • Achieve variable wall thickness
  • High precision
  • Superior repeatability
  • Material can be recycled
  • Great dimensional stability

All these perks combined, make aluminum die casting a cost-effective manufacturing process. And, the cost is unarguably one of the keys deciding factors for any project.

Aluminum Die Casting Metal Applications

Automotive: Lighter components can greatly increase the fuel efficiency of vehicles. That’s why the automotive industries use aluminum diecast parts to reduce the weight of the vehicle while meeting the structural requirements.

Telecommunication: Aluminum enclosures are widely used in the telecommunication sector. It is commonly used as RF filter housing for its excellent shielding and heat dissipation properties.

Consumer Electronics: Aluminum is the material of choice for handheld or portable electronic devices such as laptops, smartphones, cameras, etc. The lightweight, durability, and aesthetics of aluminum castings have made them very popular to end users.

Industrial Equipment: The superior thermal and electrical conductivity of aluminum die-cast metals makes them ideal for industrial applications as well. Diecast aluminum parts can withstand high operating temperatures. They are commonly used as equipment housing and heatsinks.

Common Die Casting Aluminum Alloys

A383 is very affordable and makes manufacturing more manageable. It is preferred all over the world because of its excellent properties.

A380 is a type of alloy that is frequently employed in the process of die-casting various components.

Aluminum A360 has excellent fluidity and pressure tightness, making it suitable for die casting.

It is also known as EN AC-46000. Its characteristics are suitable for different fabrication (not tempered or treated) states.

It is commonly used because of its low density and high strength-to-weight ratio.

This alloy works very well for the welding of casting aluminum parts, and it can also be used as a brazing alloy if the appropriate flux is used.

is a patented die-casted aluminum alloy designed to withstand harsh operating conditions.

The pressure-tightness features of A413 aluminum alloy are amazing. For this reason, it is an excellent material for use in hydraulic cylinders.

It has a balanced combination of physical and mechanical properties which makes it a good choice for many die-casting applications.

As the silicon crystallizes in the metal, it reinforces the cast at extreme heat and acts as a wear-resistant hard bearing.
