Advanced Aluminum Casting Alloys

Casting liquid aluminum

The world production of aluminum has exponentially grown since the early 1900’s, and it’s easy to understand why if we know its properties:

  • Lightweight
  • Strong
  • Corrosion resistant
  • Malleable
  • Highly conductive
  • Reflective
  • Non-ferromagnetic, non-pyrophoric and non-toxic
  • Recyclable

Aluminum casting alloys can be categorized into two significant groups: wrought and aluminum alloy casting composition, this can be simplified by describing the method of processing.

Wrought alloys are smelted into billets or slabs, then they are either rolled, forged or extruded into its final shape, some of them are then heat treated to further enhance their properties. These alloys have excellent mechanical properties, high structural integrity (no voids), better surface finish, ease for welding and machining as well as forming into extrusions.

Cast aluminum alloy ingots get melted and poured into molds to make the desired shape, allowing for maximum flexibility. These alloys are also lower priced compared to wrought alloys, and the casted part can also be machined to enable precision finishing.

Alloy technology has advanced more in the last 7 decades than in the last 6500 years, mainly because of humanity’s ability to build and develop on top of previous achievements; a main contributor is the computer-aided development era, which has impacted all aspects of new alloy creations. From simulation software to advanced testing equipment and advanced metallurgical tools, all of these have combined to create breakthroughs in this field that are unlocking miniaturization and high-efficiency designs, particularly in the realm of advanced aluminum extrusions and aluminum structural casting.

Amfas is proud to offer two new advancements in aluminum cast alloy technology that address two key requirements of the next generation industry, high strength cast alloy and high thermal/electrical conductive cast alloy.

 Both of these alloys are comparable to wrought alloys with the flexibility of the casting process, making these exceptionally good solutions for the products of the future.

The cast alloys presented in this white paper, including production quantities, are already being used for commercial products. Amfas is ready to help you develop the next paradigm-shifting product using our knowledge in advanced cast alloys and challenge the status quo, getting you ahead in the race for the next product that changes the world.
