Advantages of Aluminum Die Casting

Lighter parts, more finish options, resistance to temperature extremes, and more!

One of the most significant benefits of aluminum die casting is that it creates lighter parts—with more surface finishing options than other die cast alloys. Aluminum can also withstand the highest operating temperatures of all the die cast alloys. Moreover, cast aluminum is versatile, corrosion resistant; it retains high dimensional stability with thin walls and can be used in almost any industry.

Aluminum Die Casting Applications:

  • Aluminum castings improve automotive fuel efficiency by contributing to weight saving requirements
  • Aluminum is used in a broad range of networking and infrastructure equipment in the telecom and computing industries because RF filter boxes and housings require heat dissipation
  • In handheld devices, aluminum castings provide EMI/RFI shielding, rigidity, and durability with minimal weight
  • Because of aluminum’s excellent electrical performance and shielding properties, even in high-temperature environments, die cast aluminum is ideal for electronic connectors and housings

Recycling Aluminum Die Castings

Did you know? Over 95 percent of aluminum castings made in North America are made of post-consumer recycled aluminum.

There is very little functional difference between primary (extracted or pure) and secondary (recycled) aluminum when it refers to die casting. Secondary aluminum alloys are derived from mixing and melting pure aluminum with other materials such as magnesium, iron, and copper. The use of pure aluminum in casting is quite rare due to the cost of extraction. The ease of use in die casting combined with lighter weight and durability make aluminum alloys a top choice for designers from nearly any industry.

Secondary aluminum is more economical to produce than primary aluminum because it only requires 5 percent less energy to produce. Most of the energy consumption in aluminum die casting is used to heat and re-melt the metal during fabrication. For this reason, Kurt Manufacturing is able to save more time, energy and money by re-melting in-house
