Aluminum Die Casting


There are many reasons aluminum is the most commonly cast non-ferrous metal in the world. As a lightweight metal, the most popular reason for utilizing aluminum die casting is that it creates very lightweight parts without sacrificing strength. Aluminum die cast parts also have more surface finishing options and can withstand higher operating temperatures than other non-ferrous materials. Aluminum die cast parts are corrosion resistant, highly conductive, have a good stiffness and strength-to-weight ratio, as well as excellent EMI and RFI shielding properties. Since most die casting aluminum alloys are 95% post-consumer recycled material, aluminum die castings are green and sustainable.

The aluminum die casting process is based on rapid production that allows a high volume of die casting parts to be produced very quickly and more cost effectively than alternative casting processes. Aluminum die casting tools last between 50,000 and 400,000 shots, depending on the application and class of the tool produced. Once an aluminum die cast tool reaches the end of its life, it is easily recycled. Add these factors together and you will see why aluminum die casting has become the favored option for buyers worldwide.

Characteristics and Advantages of Aluminum Die Castings
• Lightweight
• Good Strength-to-Weight Ratio
• Great Resistance to Corrosion
• Excellent Electrical Conductivity
• Fully Recyclable



Best corrosion resistance. Can be more expensive depending on application.


Excellent die filling properties and good wear, high elongation value relative to other aluminum alloys.

A365 (Silafont-36)

Very good corrosion resistance, excellent weldability, and high fatigue strength.

A380 & E380

An alloy with the best cost/utility ratio.

A383, B383, & A384

All modifications of 380. Each provide better die filling, but with a reasonable sacrifice in mechanical properties, like toughness.


Used for specific applications where strength, wear-resistance/bearing properties and fluidity are a necessity.


Used for maximum pressure tightness and fluidity.


Excellent mechanical properties, very good weldability and corrosion resistance, good machinability.
