ATI Inc. ATI

ATI Company Overview

ATI Inc. is a U.S.-based specialty materials and components manufacturer focused on advanced alloys, precision forgings, and engineered materials used in highly demanding environments. The company operates primarily in the aerospace and defense, energy, medical, electronics, and industrial markets. ATI is best known for producing titanium alloys, nickel-based superalloys, specialty stainless steels, zirconium materials, and other high-performance metals designed for applications requiring strength, heat resistance, and corrosion resistance. Its products are widely used in commercial jet engines, airframes, military systems, oil and gas equipment, medical implants, and semiconductor manufacturing equipment.

ATI’s primary revenue drivers are aerospace and defense materials and engineered components, particularly jet engine materials and forged products supplied to major original equipment manufacturers and tier-one suppliers. The company traces its roots to Allegheny Ludvay Corporation and Allegheny Teledyne Incorporated before adopting the ATI Inc. name in 2017. Over time, ATI shifted from a diversified specialty steel producer toward a higher-margin portfolio centered on aerospace-grade alloys and advanced engineered materials. This repositioning included divestitures of commodity-oriented businesses and increased investment in high-performance materials manufacturing capabilities.
