ATI Forged Products

Products & Materials

ATI supplies forgings to many different market applications including Aerospace, Defense, Oil & Gas, Electrical Energy and many other industrial markets. Our forging facilities in the U.S. and Europe provide a broad range of forging technologies - from closed-die to hot die to isothermal and ring forging - in a broad range of size and weight capacities to match the most demanding requirements. Materials range from carbon and alloy steel to nickel/cobalt alloys, powder metals, titanium and other specialty metals.

Isothermal Forgings

Our isothermal forging capability in Cudahy, Wisconsin features three isothermal presses, including one of the world's largest isothermal presses. The unique design of this strain-controlled, high-tonnage press, rated at 12,500 tons, allows it to forge larger-diameter, close tolerance forgings required for today's high efficiency jet engines. Our patented SuperCooler™ technology enables us to produce highly sophisticated components that have differing mechanical properties in different parts of the same piece for greater resistance to fatigue and temperature effects.

Closed Die (Impression Die) Forgings

Today, at ATI Forged Products, we supply highly engineered closed-dies forgings for aerospace, defense, oil & gas, construction and mining and other industrial customers. Our two US based facilities have a diverse range of forging equipment that can produce a large array of complex sizes and shapes. Typical applications include structural components for aircraft, helicopters, launch vehicles, and other demanding applications. We also provide concurrent engineering and new product development support. In addition to forging operations, ATI Forged Products offers a range of engineering, die design and die sinking capabilities along with post-forging operations including heat treatment, non-destructive and destructive testing, machining and inspection.
