Super Alloy Investment Castings

Our capability to produce “Super Alloy” investment castings allows us to achieve the following:

• Produce casting parts with high geometric complexity, through holes, thin walls and more
• Convert multi-part assemblies into single castings
• Achieve tight tolerances of +/-.005” per linear inch to eliminate post machining and finishing

The following are some examples of the parts and components manufactured using “Super Alloys”:

• Industrial gas turbines
• Aerospace engine components
• Turbine case and disk parts
• High temp valve bodies
• Butterfly valves
• After burner linkages
• Turbine exhaust housings

There are several reasons behind the increasing popularity of superalloy castings spanning a variety of applications and industries. These benefits of using these materials is as follows:

• Integrated Design: The most striking benefit of super alloy castings is the elimination of weldments, as it helps increase the service life of the castings by increasing their strength. Part designs can be integrated easily with the help of the flexibility of the investment casting process. A single casting can integrate a number of welded components and machined features which helps eliminate the requirement of complex assemblies, and multiple components.
• A Strong End Product: The super alloys are the result of modified alloy compositions which help make the product resistant to corrosion and provide excellent mechanical properties at elevated temperatures. The grain size of the castings can be engineered, and their fatigue life is increased by employing special processing parameters.
• Intricate Shapes: Do you want to manufacture complex shapes with high precision? This is made possible by the use of superalloy castings. In many cases secondary operations can be eliminated surfaces can be achieved by using super alloy investment castings.
• High Precision: All the minute details of a part, such as surface textures, teeth, graphics, and splines are produced with high precision. Detailed surface features are achieved with accuracy which gives a proper form and function to the components.
