New, Sleeker Samsung Smartphone Built Stronger with Alcoa’s Aerospace-Grade Aluminum

June 4, 2015

Alcoa-invented material strengthens phone’s structure by 70 percent

Lightweight metals leader Alcoa (NYSE:AA) today announced that it is
supplying a high-strength, aerospace-grade aluminum to Samsung for its
latest smartphones —the Galaxy S6 and S6 edge. This marks the first time
the global electronic giant will use an aluminum frame for its Galaxy S
flagship model. The Company’s aerospace-grade aluminum, 6013 Alcoa Power
Plate, is 70 percent stronger than standard aluminum used in
similar devices, creating a thinner, lighter, sleeker design.

“When we designed the metal framed Galaxy S6 and S6 edge, it was
important to find a strong yet light metal that would create a device
capable of exciting our customers,” said DJ Koh, CTO and Executive Vice
President of Mobile Communication Business at Samsung Electronics.
”Alcoa’s Power Plate is the perfect fit to create the phones that our
customers want: thinner, lighter, and stronger.”

Smartphones with metal frames are expected to grow almost 250 percent1
by 2016 from 2014, creating stronger demand for aluminum to protect
mobile devices. Developed by Alcoa Technical Center scientists,
innovators in metal science, the Alcoa Power Plate aerospace-grade
aluminum combines advanced strength and corrosion resistance for
products that require superior durability.

”Alcoa’s Power Plate has been battle tested across aerospace, automotive
and military uses, proving it can withstand the heavy use and tough
treatment endured by mobile devices,” said Ray Kilmer, Executive Vice
President and Chief Technology Officer of Alcoa. “Samsung’s leading
designers wanted to develop a thinner, sleeker device without
sacrificing durability. Innovating with Samsung, Alcoa’s metallurgists
identified a solution that gives the Galaxy one of the strongest and
most durable aluminum bodies available on the market.”

Samsung Galaxy S6 phones with Alcoa Power Plate are now available
globally.

Alcoa’s innovative technologies for the consumer electronics market
support the Company’s broader strategy to grow its value-add portfolio.
Other Alcoa consumer electronics solutions include ProStrength™,
a proprietary surface finishing technology also using aerospace-grade
aluminum for thinner, lighter and stronger mobile devices.
