Turbine Engine Material Spectrum
A modern gas turbine engine uses five or more different superalloy families across its sections, each selected for the specific temperature, stress, and environmental conditions at that location. Titanium alloys (Ti-6Al-4V, Ti-5Al-2.5Sn) serve the fan and low-pressure compressor where temperatures are moderate but weight savings are critical. Inconel 718 dominates the high-pressure compressor and intermediate turbine sections where high strength and moderate temperature resistance are required. Waspaloy and René alloys serve the high-pressure turbine discs. Single-crystal nickel alloys (CMSX-4, PWA 1484) and directionally solidified alloys (MAR-M-247) handle the hottest turbine blade positions. Cobalt alloys (Haynes 188, Stellite) serve combustion liners, vanes, and wear surfaces.
Our Turbine Component Capabilities
CastAlloy provides manufacturing solutions across this full material spectrum. Our capabilities include vacuum investment casting of turbine blades, nozzle guide vanes, combustor liners, shrouds, and structural cases in nickel and cobalt superalloys. Closed-die and isothermal forging produces turbine discs, compressor discs, shafts, and spacers in Inconel 718, Waspaloy, and titanium alloys. Precision CNC machining brings cast and forged components to final specifications with the tight tolerances and surface finishes that turbine assembly demands. And our comprehensive NDT capabilities verify every component's integrity before delivery.
