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 Samsung.
