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.
We specialize in highly repeatable short production runs of superalloy investment castings in the 0 to 20 lbs range, and can produce 100+ lbs castings when required, as well as:
From concept to completion, PCT ensures that superalloy investment castings meet the form, fit, and function of your design.
Today's fourth generation of superalloys can withstand temperatures well over 2000° F, and feature chemically engineered grain structures for increased hardness. Superalloys are precipitation strengthened to remove crystal impurities, further enhancing mechanical properties by removing stress anomalies.
While superalloy mechanical properties vary by grade and type, common characteristics include high levels of heat resistance, abrasion resistance, anti-oxidation, and corrosion resistance.
The hardness of superalloys make them difficult to machine. Our Netshape, as-cast parts reduce or eliminate the majority of costly machining, while still maintaining precision tolerances within +/- .005 inches per linear inch.
Precision Castings of Tennessee automates the majority of the superalloy casting process, ensuring we produce consistent results that save our customers money. Casting superalloys is a somewhat delicate process that requires constant monitoring, and is highly susceptible to cracking when performed by untrained foundries.
Superalloy's ability to operate at higher temperatures provides greater opportunity for efficiency and extended component life over typical alloys. High temperature applications, such as aerospace and power generation turbines, absolutely require the unique mechanical properties of superalloys.
Featuring excellent creep resistance, anti-oxidation properties, and strong surface stability, superalloys are a necessity for today's high temperature industrial applications. Our inventory of superalloys includes duplex alloys, hastelloys, nickel based, nickel-chromium, cobalt based, and proprietary combination alloys.
