Rotorcraft
When everything rotates, every ounce matters.
Rotorcraft put extraordinary demands on materials. Critical components must carry tremendous centrifugal and dynamic loads, withstand constant vibration and fatigue, and do it without unnecessary weight. ATI produces the advanced titanium, nickel and specialty-steel materials and forgings behind some of the hardest-working components on military rotorcraft.
Forging: Complexity is our Comfort Zone.
Some of the hardest working parts of a rotorcraft are also some of the hardest to make. ATI produces highly complex titanium and specialty-steel forgings for dynamic rotor components, controlling material flow and microstructure to put strength, toughness and fatigue resistance where the design demands it.
Materials: Strength Without the Weight.
Rotorcraft have to lift themselves before they can lift anything else. ATI's titanium, nickel and specialty-steel alloys deliver the strength, fatigue resistance, toughness and corrosion resistance critical components demand - while helping designers keep weight under control.
Going Vertical with a Superior Supply Chain.
Critical components demand more than the right alloy. They demand control over how it's made. ATI integrates melting, forging, machining and finishing capabilities to control more of the journey from raw material to flight-ready component - reducing handoffs and supply-chain complexity.
Dynamic Rotor System
Where rotation becomes lift.
Pulled in every direction.
Rotation creates enormous centrifugal forces while maneuvering adds constantly changing loads, vibration and stress. These critical connections need exceptional strength and fatigue resistance to perform cycle after cycle.
Complex forgings for complex forces.
ATI produces highly complex, near-net titanium and specialty-steel forgings for critical rotor components. Precise control of material and microstructure delivers the strength, toughness and fatigue resistance these dynamic components demand.
Rotor Blade Protection
The leading edge takes the beating.
Speed makes small things hit hard.
Particles and moisture that seem harmless on the ground become relentless sources of erosion at rotor speed. Over time, repeated exposure can degrade blade surfaces and aerodynamic performance.
Titanium on the front line.
ATI produces titanium erosion strips for rotor-blade leading edges, combining lightweight strength, corrosion resistance and durability to protect the surface that meets the environment first.

Power has to make it to the rotor.
Torque never takes a flight off.
High rotational loads combine with vibration, friction and heat to put drivetrain components under continuous stress. The materials must maintain strength and resist fatigue and wear through demanding operating cycles.
Materials made to keep power moving.
ATI produces titanium, nickel and specialty-steel alloys for critical drivetrain components, providing the strength, toughness and fatigue performance needed to transfer power reliably from engine to rotor.
Structures & Survivability
Built for what happens beyond the rotor.
Protect more. Carry less.
Added strength and protection usually come with added weight - and every additional pound competes with fuel, payload and range. Rotorcraft need materials that can withstand impact, structural loads and demanding environments without unnecessarily weighing the aircraft down.
Strength where every pound counts.
ATI titanium and specialty steels bring high strength, toughness and durability to landing gear, armor, cockpit structures, stabilizers and other critical components - helping designers balance protection and structural performance with the constant demand to control weight.
