Apple has applied for a patent for a method to fabricate a sheet of metallic glass matrix composite. That strange name is often referred to as liquid metal. Some details of the patent application are in PatentlyApple’s Apple Reveals New Machinery for Creating Liquidmetal Forms.
In order to make cool products with this exotic material one must first invent equipment that could properly processes and control it. Today’s patent relates to sheet casting of metallic glasses, and more particularly to twin roll sheet casting of bulk metallic glasses and composites in an inert environment.
In the end Apple hopes to develop cases which are as strong as metal but lighter than aluminum.
