Aluminum Alloy Casting

Aluminum alloys contain a high percentage of aluminum alloyed with copper, magnesium, silicon, tin, manganese or zinc. They are lightweight and corrosion resistant and are the alloy of choice for many aerospace applications due to these properties. Aluminum alloys can be strengthened through either heat treatment or cold-working processes, depending on the alloys.

Precision Investment Casting for Aluminum Alloys 

Engineered Precision Casting Company, Inc. provides aluminum alloy casting for prototype to large-scale production runs. We use a master heat system to strictly control our metal inventory and have experience pouring over 75 ferrous and non-ferrous air-melt alloys. For precision investment casting applications requiring additional finishing and services, we also offer heat treatment, non-destructive testing, and more.

Our specialty is casting complex parts for demanding applications. We have extensive experience casting thin-walled and multi-cored aluminum projects for various aerospace customers, utilizing our extensive casting history dating back 70+ years. Contact us to discuss your investment casting project or for assistance selecting the appropriate alloy for your application.

Aluminum Alloy Casting Materials

Aluminum alloys are used for investment casting a wide range of components including those for aircrafts and engines including fittings, housings, levers, valves, impellers, and more. Our aluminum alloy casting material options include: 

  • A356: The alloy contains silicon, magnesium, iron and zinc. It provides excellent corrosion resistance and good weldability and can be heat treated to improve strength.  It is one of the most commonly used aluminum alloys and is a good substitute for 6061 aluminum bar stock.
  • C355: contains silicon, iron, copper, manganese, magnesium, zinc and titanium. It offers increased strength compared to A356 and is often used in applications requiring strength at higher temperatures.
  • A357: It is composed of silicon, beryllium, iron, copper, magnesium, titanium, zinc and manganese. It is typically used for structural components as it is one of the highest strength aluminum alloys. 
  • F357: is a beryllium free variant of A357.
