Apple Inc. (NASDAQ:AAPL) has recently renewed its exclusive licensing deal with LiquidMetal, which is an exotic metal alloy that works like plastic. Apple was also granted a patent by the U.S. Patent and Trademark Office for use of the material combined with glass displays, including ones made with sapphire.
The patent essentially describes the process of bonding as it relates to a LiquidMetal device case. The patent hints at future iOS devices that are LiquidMetal-built.
There are rumors that hint at sapphire glass being used in the upcoming iPhone 6 and we know that Apple has a partnership in place with GT Advanced Technologies for a sapphire production plant in the U.S. What makes sapphire appealing is that it is more scratch-resistant and is cheaper than Gorilla Glass.
LiquidMetal has been used generally for medical and military applications. It is known for its ability to resist wear and corrosion.
