Defense

Aircraft that need to fly faster and maneuver harder. Naval systems engineered for decades of service. Ground vehicles that need more protection without more weight. Missiles ramping today and hypersonic systems pushing beyond Mach 5. The advanced materials behind it all? ATI.
Why ATI

More Than Materials. Material Advantage.

ATI produces the advanced materials behind some of the most demanding defense systems in air, on land and at sea. What sets us apart is what we can do with them: solve new materials challenges, produce alloys few others can, and deliver them at the scale critical programs demand.

From Melt to Mission, ATI Controls More of the Process.

Integrated capabilities spanning melting, forging, rolling, finishing and additive manufacturing mean greater control of quality, production flow and supply. Fewer handoffs help ATI move faster, scale production and respond as defense requirements change.

Hard-to-Make Materials. 
Hard-to-Match Portfolio.

Titanium. Nickel superalloys. Specialty steels. Niobium. Hafnium. Zirconium. ATI produces a differentiated portfolio of advanced materials engineered for the extremes of defense, from lightweight armor and high-temperature propulsion to nuclear and hypersonic applications.

Take Out the Weight. Add Capability.

ATI titanium and specialty alloys help defense systems do more with less weight - supporting greater mobility, range and maneuverability while delivering the strength, durability and protection demanding applications require.

From Proven Programs to What Comes Next.

ATI materials perform across established defense platforms while our materials scientists work alongside customers to solve the challenges ahead. From rapidly growing missile demand to next-generation hypersonics, we develop the alloys and processes customers need to move new technologies toward production.
