Aluminum Investment Castings


​Overcoming Steel's Weight Problem


​Aluminum investment castings, on a pound for pound basis, are stronger than steel and have greater heat dispersion capabilities. Aluminum castings are ideal for weight reduction applications in the aerospace, marine, military, medical, and automotive industries.

Precision Castings of Tennessee specializes in producing near-net shapes of virtually any aluminum investment casting within 0 to 30 lbs and converting multiple parts into single assemblies. As a leading investment casting supplier, our capabilities include:

  • Intricate, near-net shape parts without secondary machining
  • Easily convert multiple parts into single assemblies
  • Thin walls for weight reduction opportunities
  • Surface texture of 125 RMS or better
  • Tolerances within +/- .005 inches per linear inch
  • Highly complex dimensional geometry


From concept to completion, PCT ensures that your aluminum investment castings meet the form, fit, and function of your design.

Form – Aluminum's unique physical characteristics


Aluminum investment castings enjoy a high level of corrosion resistance with proper coatings, and are suitable for high pressure applications once impregnated (anodized aluminum.)

Fit – Making aluminum castings work for you


Investment casting generally eliminates costly machining requirements. The result is lower labor costs and stronger, more accurate parts with higher levels of repeatability.

We provide various heat treating services for aluminum hardening and softening, including T2 annealing, T4 solution treatment & natural aging, T6 solution treatment & artificial aging, and T61 solution quenching & aging.

Function – Real-world aluminum investment casting examples


Aluminum's unique weight properties and resistance to corrosion make it ideal for a variety of industries. Aluminum is commonly used for medical equipment, military munitions, electronics, and aircraft parts.

Unlimited Alloy Choices

Featuring unlimited alloy choices, investment castings are the most versatile metal forming methods available. Designers are not limited to any particular alloy, as the investment casting process allows for easy alloy substitution using the same tooling.

Each alloy has unique mechanical properties, including varying degrees of hardness, corrosion resistance, electrical conductivity, and ductility. Visit each alloy page for real world examples of how Precision Castings of Tennessee is changing the investment casting industry.
