Alcoa’s ColorKast™ Die Cast Technology Used by Samsung; More Consumer Electronic Manufacturers Set to Use Breakthrough Product

PITTSBURGH–Alcoa (NYSE:AA) today announced the first commercial success of its
ColorKast™ technology in the consumer electronics market. 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 products.

ColorKast™ is a breakthrough aluminum die casting technology that allows
consumer electronics manufacturers to create cosmetically high-end,
lightweight, and cost-effective components for portable electronic
devices using proprietary alloy, process, and finishing technologies
developed at Alcoa Technical Center. The result is cosmetic 3D products
with the rich, metallic “look and feel” of anodized aluminum, and the
high productivity and cost advantages of die castings as compared to
unibody machining processing or magnesium die casting. In addition,
products made from ColorKast™ create a better green solution relative to
plastics or composites because aluminum is infinitely recyclable.

The performance and aesthetic requirements of ColorKast™ have been
validated with Alcoa’s exclusive manufacturing partner, GK (Global
Kwangsung) in South Korea, before being introduced to the market,
leading to the success of the first commercialized application at
