Ati Inc.
A maker of high-performance titanium and nickel alloys, ATI supplies the hot sections of jet engines and flat-rolled specialty metals for aerospace, defense, and energy customers through its High Performance Materials & Components and Advanced Alloys & Solutions businesses. Its roots reach back to 1901's Allegheny Steel & Iron, and the modern company took shape in 1996 as a merger of Allegheny Ludlum and Teledyne, later shortening its name from Allegheny Technologies to ATI. The "Allegheny" name honors the Pennsylvania region where its steelmaking ancestors were founded.
