Aerospace Engines
6 out of 7 Alloys in the Hot Section of a Jet Engine are Produced by ATI.
We are the first-call partner of every major aerospace manufacturer. Our expertise and experience are relied upon to push propulsion thresholds past previously known physical limits.
Melt: Purity from the Start
Performance starts with what goes into the metal... and what stays out. ATI is the industry leader in high-purity nickel-based superalloys, controlling chemistry and microstructure for longer life and greater durability in the extreme conditions inside a jet engine.
Powder: Performance by the Particle
Powder metallurgy takes materials performance even further. ATI controls chemistry, particle size, cleanliness and density from atomization through Hot Isostatic Press, producing ultra-clean powder alloys with fine, uniform microstructures for greater durability and performance in next-generation jet engine disks.
Forging: We Make It. Then We Forge It.
ATI produces the advanced nickel superalloys for jet engine disks, and has the rare capability to forge them, too. We're the only producer of isothermally forged jet engine disks for all three major engine OEMs, and one of only two integrated U.S. producers forging rotating components from our own nickel superalloys.
Rotating Turbine Disks: High Pressure Compressor
Where pressure builds, materials matter.
More performance. Same unforgiving physics.
Higher pressure ratios and temperatures can improve engine efficiency - but they also put greater demands on rotating disks. The material must maintain its strength and resist fatigue over thousands of cycles while spinning under tremendous loads.
It's what's inside that counts.
ATI produces the advanced nickel-based superalloys and powder materials engineered for these rotating disks. Precise control of chemistry, cleanliness and microstructure delivers the strength, fatigue resistance and durability needed to extend disk life and push engine performance further.
Rotating Disks: High-Pressure Turbine
This is where things get hot. Really hot.
Keeping strength when the heat is on.
Heat changes what metals can do. As temperatures rise, maintaining strength becomes harder and resistance to creep, fatigue and crack growth becomes increasingly critical. And because hotter engines can deliver greater efficiency, the material challenge keeps moving higher.
Made for the hottest rotating hardware.
ATI produces advanced nickel-based superalloys - including powder alloys engineered for high-temperature turbine disks - and carries that materials expertise through HIP and isothermal forging. Precise control of chemistry, cleanliness and microstructure creates disks engineered to retain strength and durability at temperature.
Rotating Turbine Disks: Low Pressure Turbine
Turning heat into thrust.
Heat. Force. Repeat.
Low-pressure turbine disks operate under a demanding combination of centrifugal loads, elevated temperatures and repeated thermal and mechanical cycling. Over thousands of flights, the material must maintain its strength while resisting fatigue, creep and crack growth. Research on turbine disks specifically identifies the interaction of centrifugal and thermal stresses, fatigue, creep and environmental effects as central life considerations.
Built for a long life in the hot seat.
ATI produces and forges nickel-based superalloys engineered for the demands of rotating turbine disks. Through precise control of chemistry, cleanliness and microstructure - and advanced powder metallurgy, Hot Isostatic Pressing and forging - we create materials engineered to maintain strength at temperature, resist fatigue and slow crack growth over a long operating life.
Exhaust Nozzle
Where propulsion makes its exit.
Hot. Fast. Constantly changing.
Exhaust temperatures and flow conditions shift throughout every flight. Nozzle materials must handle repeated heating and cooling, vibration and corrosive exhaust environments while maintaining strength and dimensional stability.
Take the heat. Keep it light.
ATI produces titanium alloys that combine low weight with the strength, corrosion resistance and thermal durability demanded by exhaust-system components.
Fan Blades
One strike and you are out
Spinning at extreme rotational velocities, modern fan blades must be able to handle tremendous rotational force and torque. The threat of foreign object debris, like a sudden bird strike, also demands a material that can survive a violent, high-velocity impact.
Redefining Cutting-Edge
Our high-quality titanium alloys are the ideal material for components with such an extreme envelope of requirements, making us a preferred supplier for manufacturers.
