The incredibly promising metal alloy from Liquidmetal
The problem with alloy is that, although it's easier to make (no quick cooling required), churning out large sheets of the stuff in a controllable thickness is a little more tricky. Prized as a stronger alternative to plastic and more flexible alternative to metal, Liquidmetal doesn't fit into any of our current methods of manufacturing; stretching and molding the sheets like we do now just snaps them in half.
All Liquidmetal really needs to take off, though, is a big backer willing to put in the effort to put it to work. And with Apple's patent that covers various production methods for large sheets of ""metallic glass"" in thicknesses between 0.1mm and 25mm, it looks like we've got ourselves a winner. And the patent is very clear about the fact that they'll be turning the stuff into iPhones, iPads, watches
Of course, wild innovations often stay in patent purgatory never to become a reality, you know, just in case. But Apple's already making their SIM ejector pin out of Liquidmetal, so they're already well on their way. [Electronista via Engadget]
