Superalloy castings and forgings for turbine hot sections

BOTTLENECK

Doncasters exemplifies the handful of qualified foundries where ceramic-core shortages and low yields constrain turbine output.

Nickel-superalloy castings and forgings for turbine hot sections, including single-crystal blades. A metallurgical bottleneck: only a handful of qualified foundries exist, and low yields plus ceramic-core shortages constrain how fast OEMs can ramp turbine output. These suppliers hold pricing power over OEMs.

Investment-cast and forged nickel-superalloy hot-section components for gas turbines (single-crystal and directionally solidified blades and vanes, discs, casings); a deep metallurgical bottleneck sitting behind OEM turbine output.

What the evidence shows

A small portion of HPAs is used for fuselage structural and fastener components.
