Alcoa Technology Puts Aerospace-Grade Aluminum on Mobile Devices

December 20, 2013

Proprietary Technology to Enable Thinner, Stronger Electronic Gadgets

Alcoa (NYSE: AA) has developed a proprietary surface finishing
technology that enables consumer electronics companies to use
aerospace-grade aluminum to make thinner, lighter and stronger mobile

Alcoa’s new ProStrength™ Finishing Technology is a process that allows
mobile device manufacturers to design clear or color-anodized durable
surfaces utilizing high-strength, heat treatable aluminum alloys used in
the aerospace and defense industries. Using high strength alloys could
reduce the thickness and weight of a device by more than 50 percent.

Device size as well as design look and feel are significant factors for
consumers in making purchasing decisions on consumer electronics. Both
features were identified as important by more than 50 percent of
consumers surveyed by Accenture on the importance of features to
purchase decisions. (Source: The 2013 Accenture Consumer Electronics

“Consumer electronics makers had been exploring ways to create beautiful
anodized finishes on aerospace-grade aluminum alloys because they are
among the strongest, yet lightest metals available,” said Ray Kilmer,
Executive Vice President and Alcoa Chief Technology Officer.
“ProStrength’s anodized finish creates the metallic look and feel that
consumers prefer, and the high-strength aluminum allows manufacturers to
produce thinner, lighter, and more durable enclosures.”

According to Leighton Cooper, Director of Technology at the Alcoa
Technical Center, the Company’s expertise in aluminum finishing and
close ties to the consumer electronics industry was critical in reaching
this development milestone. “ProStrength™ Finishing Technology brings
together the perfect combination of aesthetics and function,” he said.
“Being able to use aerospace-grade alloys promotes the growing trend for
ever thinner and lighter mobile devices.”

Alcoa developed its ProStrength™ Finishing Technology at the Alcoa
Technical Center, the world’s largest light metals R&D facility located
outside Pittsburgh. The company has worked with the world’s leading
consumer electronic (CE) companies and designers to enable the use of
aluminum in mobile devices. Aluminum’s penetration in the CE market has
grown as OEMs look to its aesthetic qualities, light weight and ability
to dissipate heat, all of which enhance the durability, performance and
attractiveness of devices for consumers.

Last year, Alcoa announced another consumer electronics breakthrough
with its ColorKastTM
Die Cast Technology that is used by Samsung. As a result of this
innovative technology, Alcoa can produce color anodizable aluminum die
cast components with high-end cosmetics. The first use of the ColorKast™
technology appears on Samsung’s new digital camera NX210 and other
consumer electronic OEMs are preparing to apply this technology to their
