A couple of years back, Apple purchased the patents from a materials firm by the name of Liquidmetal. The company made an amorphous metal alloy which combined high strength with the ability to be bent and flexed into complex shapes without suffering deformation. Many have speculated what Apple might use the technology for, but according to Liquidmetal's CEO, those alloys are already in Apple products.

According to 9to5mac, we probably won't see Liquidmetal featured prominently in any upcoming products. Chances are, it's being used in batteries, not to mention the SIM card ejector tool, which many believe to be made of Liquidmetal. 9to5mac also spoke to a Liquidmetal investor who claims it will be a few years "before Liquidmetal can be used in a large scale for Apple products." Whatever large scale entails, hopefully it'll be interesting. [9to5mac via Business Insider]
