• State-of-the-art, 3D printing metal powder production facility located at Alcoa’s Technology Center outside Pittsburgh, PA
• Alcoa will produce proprietary titanium, nickel and aluminum powders optimized for 3D printing aerospace parts
• Builds on more than a century of experience in metal alloy development and metal powder production

Lightweight metals leader Alcoa (NYSE:AA) has opened its
state-of-the-art, 3D printing metal powder production facility. Located
at the Alcoa Technology Center, the world’s largest light metals
research center, the Company will produce proprietary titanium, nickel
and aluminum powders optimized for 3D printed aerospace parts. Alcoa
also has invested in a range of technologies to further develop additive
processes, product design and qualification.

“Alcoa is forging a leadership path in additive manufacturing with a
sharp focus on the critical input material—metal powders,” said Alcoa
Chairman and Chief Executive Officer Klaus Kleinfeld. “We are combining
our expertise in metallurgy, manufacturing, design and product
qualification to push beyond the possibilities of today’s 3D printing
technologies for aerospace and other growth markets.”

Metal powders used for 3D printing durable, high-quality aerospace parts
are available in limited quantities. Through this expansion, announced
in September 2015, Alcoa will develop materials with the specific
properties needed to 3D print high-performance components. Alcoa has
deep expertise in metal alloy development having invented most of the
aluminum alloys used in aerospace today. In addition, it has a 100-year
history in aluminum metal powder production, primarily for rocket fuel,
paint and other products.

The facility will form part of Arconic following separation
from Alcoa’s traditional commodity business in the second half of
2016. The plant is part of a $60 million investment in advanced 3D
printing materials and processes that builds on the Company’s 3D
printing capabilities in California, Georgia, Michigan, Pennsylvania and
Texas. In addition to producing powders, Alcoa is focused on advancing a
range of additive techniques, including its recently unveiled Ampliforge™ process,
a hybrid technique that combines additive and traditional manufacturing.
Using the Ampliforge™ process, Alcoa designs and 3D prints a near
complete part, then treats it using a traditional manufacturing process,
such as forging. The process enhances the properties of 3D printed
parts, increasing toughness and strength versus parts made solely by
additive manufacturing, and significantly reduces material input. Alcoa
is piloting the technique in Pittsburgh and Cleveland.

Alcoa has manufactured 3D printed products for the past 20 years and
owns and operates one of
the world’s largest HIP (Hot Isostatic Pressing) complexes in
aerospace. HIP technology strengthens the metallic structures of
traditional and additive manufactured parts made of titanium and nickel
based super-alloys. Through the RTI
acquisition, Alcoa gained 3D printing capabilities in titanium and
other specialty metals for the aerospace market and other growth
industries.

Demonstrating its leadership in additive manufacturing, Airbus
recently selected Alcoa to supply 3D printed titanium fuselage and
engine pylon parts for commercial aircraft. Alcoa expects to deliver the
first additive manufactured parts under the agreement later this year.

Alcoa Aerospace

Alcoa’s aerospace businesses will be a key component of Arconic
following Alcoa’s
separation. Arconic will be a premier innovator of high performance
multi-material products and solutions in attractive growth markets,
including aerospace. The separation remains subject to the satisfaction
of certain conditions, including obtaining final approval from the Alcoa
Board of Directors, receipt of a favorable IRS ruling and opinions of
Alcoa’s tax advisors regarding certain U.S. federal income tax matters
and the effectiveness of the Form 10.
