Die casting aluminum offers several advantages over other metal-forming processes that might make it the appropriate choice to create your aluminum parts.

Aluminum alloys are lightweight and possess high dimensional stability for thin walls and complex part geometries. Aluminum withstands good corrosion resistance and mechanical properties as well as high thermal and electrical conductivity, making it a good alloy for die casting. Low-density aluminum metals are essential to the die casting industry. The Aluminum Die Casting process retains a durable strength at very high temperatures, requiring the use of cold chamber machines. The molten metal is still contained in an open holding pot which is placed into a furnace, where it is melted to the necessary temperature. The open holding pot is kept separate from the die casting machine and the molten metal is ladled from the pot for each casting because these high temperatures would damage the normal pumping system. The pressure requirements for cold chamber castings are higher than those of hot chamber die castings typically. One of the most important thing is the ability to produce very complex shapes that neither extrusion nor machining can effectively create. A perfect example of this is the production of complex automotive parts, like transmissions and engine blocks. Other processes cannot consistently achieve the complexity and tight tolerances required for these products.

Some other advantages include the ability to have textured or smooth surfaces and the capacity to accommodate both large and small parts.
