Advanced Solutions for Higher Performance and Longer Life
From its beginnings in the early 1970s as a process for making wear-resistant tool steel products, powder metal technology has expanded to cover major markets in aerospace, power generation, marine, oil and gas, medical products and manufacturing – wherever superior performance in extreme temperature, corrosion and wear environments is needed.
Aerospace/Defense
We pioneered Hot Isostatic Pressing (HIP) PM (powder metal) in jet engine design, producing the first rotating turbine parts for the General Electric T-700 engine. Today, over 150,000 of our superalloy PM turbine discs, seals, spacers and blade retainers are currently in service on commercial and military airplanes and helicopters. In the demanding environment of today’s jet engines, ATI Powder Metals parts perform with elevated temperature creep resistance and fatigue life superior to that of conventional cast and wrought superalloys. PM parts, with their fine, equiaxed grain structure, can be ultrasonically inspected with greater sensitivity than other materials, permitting designers to make full use of the higher strength and fatigue life of PM parts. In addition to superalloys, with our Titanium Gas Atomizer (TGA), we can produce advanced PM titanium alloys, titanium aluminides, and powder for metal matrix composites (MMC) and intermetallic matrix composites (IMC) for exhaust ducts and hot airframe parts in next-generation aircraft.
We are also the world’s leading supplier of GRCop-84, developed at NASA Glenn Research Center to manage the enormous thermal stresses rocket engine liners undergo while separating rocket flame from liquid hydrogen fuel.

Industrial
Powder metal (PM) technology can deliver longer life and lower costs in many applications in manufacturing, particularly where wear and corrosion are factors. ATI PM clad mill rolls for steel and food processing reduce lifecycle costs in these competitive industries. PM cladding is also used successfully in valve seats and gates; bearings for pumps and many other critical wear components for processing equipment. Our clean, monolithic material can greatly reduce costs in highly machined components like manufacturing dies, where high reject rates caused by material defects can be expensive.

Other Markets
Wherever there’s a need for the highest possible lifecycle performance in conditions of extreme heat, wear and corrosion, powder metal (PM) technology can be a cost-saving option. ATI Powder Metals has the industry’s best combination of experience, technology, integrated production, and customer service. In addition, PM’s superior microstructural characteristics give it an advantage over other materials.
